It’s windy-past lives in power exchange mode

On June 6th, the National Development and Reform Commission, the Ministry of Ecology and Environment, and the Ministry of Commerce once again pushed the development of new energy vehicles-"Implementation Plan for Promoting the Updating and Upgrading of Key Consumer Goods and Smooth Resource Recycling (2019-2020)" was released. The importance of this document can basically be understood as the main theme of the post-new energy vehicle era. That night, we took a look at the dynamics in the circle, which is roughly like this:

From a fundamental point of view, this is a promotion document for digesting production capacity nationwide, which is good for all companies in all industries, large and small. On the other hand, the switching of fuel vehicles in China is the icing on the cake. However, this Dragon Boat Festival, the vast majority of car companies and pile companies have spent a uneasy festival. To sum up, people who have no long-term worries will have near worries.

From the point of view of energy supplement, there are several points worthy of attention in this document: how to go in the future in the process of changing tracks from policy-driven to market-driven in China’s new energy automobile industry.

one

Gradually realize battery platformization and standardization.

Prepare for modular car building, dynamic circulation of power batteries and ladder utilization, and do not rule out the possibility of introducing unified standards for power batteries in the future.

2

Vehicle-electricity separation

Reduce the threshold for car purchase in the post-subsidy era, activate the enthusiasm of new energy vehicles, and protect the stable development of the industry.

three

Develop new energy vehicle products with combination of charging and replacing electricity, flexible configuration and long driving range.

1. The energy supplement system adds electricity exchange, providing a new solution in terms of energy supplement efficiency. 2. The power battery can be configured flexibly after modularization to meet different travel scenarios and demands.

four

Smooth the whole life cycle of resources and improve the utilization efficiency.

The specification for step utilization, disassembly and scrapping of power batteries has entered the research stage.

Judging from the logic of the new energy automobile industry in the full text of the policy, it mainly guides the industry from two aspects: encouraging the upstream and downstream of the new energy automobile industry to continue research and development, promoting cost reduction and efficiency improvement, perfecting the energy supplement system and improving the market application of new energy vehicles. The document specifically mentions that it is necessary to learn from the power exchange mode and application experience in the field of public services, and encourage enterprises to develop new energy vehicle products with the combination of charging and power exchange, flexible battery configuration and long driving range. Therefore, we feel it is necessary to show past lives, the power exchange mode, to everyone.

01 Sadness Xia Jiaxi and His Better Place

In 2007, Shay Xia Jiaxi put forward the power exchange technology, and then founded a power exchange company called Better Place in Israel. After the financing of $850 million was changed in 2013, Xia Jiaxi and his dream of Better Place collapsed. Even though the valuation reached an unprecedented $2.25 billion at that time, the hopeless power exchange model was ruthlessly abandoned by capital.

Xia Jiaxi’s Ambition and the Legacy of Better place

In the early days of its establishment, Xia Jiaxi foresaw that the power battery, a key component that directly affects consumers’ desire to buy, would not improve by leaps and bounds in the short term. The most direct way to solve the mileage anxiety is to form the same energy supply efficiency as fuel supply for fuel vehicles. The energy supplement market bred by the emerging industry of electric vehicles will directly subvert the existing energy structure and consumption mode. Under such a market positioning setting, Xia Jiaxi boldly left SAP.

One year after the establishment of Better place, Israel’s first "power exchange station" was established. First, it signed a cooperation agreement with Renault to provide 100,000 Fluence ZE electric vehicles (but the actual order was less than 1%). Better Place started with 750 drivers in Israel, and the charge for electricity exchange service includes battery rent and electricity exchange fee. Although the hardware cost, battery maintenance cost and education cost of consumers and enterprises were incomprehensible at that time, Xia Jiaxi did not hesitate to continue to burn money in Denmark and the United States, but at that time, car companies still had great doubts about the development of new energy vehicles, and the convenience and use cost of customer-side power exchange mode were not particularly different from those of traditional fuel vehicles. Better Place only launched thousands of vehicles around the world until it was closed.

The end of the road for Better Place seems to be ill-timed now. After all, the overall environment of the new energy automobile industry is far from the same. However, Better Place has left a complete chassis power exchange technology for future generations, and the value generated by the experience in the operation process is immeasurable.

02 Phased tasks of State Grid

863 Program-the Beginning of Power Exchange Technology

In 2006, the domestic electric vehicle industry was still in its infancy. The State Grid responded to the call of the country to start the electric vehicle project, and Zhejiang Power Grid is the top priority to implement the project. At that time, the first project leader of Zhejiang Power Grid participated in the project was Mr. Nie Liang (the first person in the domestic market application field of power exchange mode). In 2010, his team developed and completed the first licensed pure electric vehicle in China, and completed the reserve of basic power exchange technology. In the same year, Nie Liang was responsible for building the Zhejiang project of intelligent charging and replacing power service network. Different from Better Place, a pioneer in power exchange, State Grid developed a set of standard box power exchange technology after understanding the chassis power exchange technology. In Hangzhou, 500 power exchange taxis were piloted with Langyue and Prima models and high box standard boxes, and the business model of "separation of vehicles and electricity and mileage charging" was put forward and verified for the first time in this project.

Power exchange stations and standard boxes piloted by State Grid in Hangzhou

It can be said that the power exchange technology was basically a system at that time, and the pilot effect was quite satisfactory. Later, the Beijing-Shanghai trip organized by State Grid set a fire for the development of power exchange. What’s more interesting is that. In August 2010, State Grid joined the "China Enterprise Electric Vehicle Industry Alliance" and served as the chairman of the charging and service professional committee. At that time, State Grid determined the basic idea of its own intelligent charging and replacing operation mode, that is, mainly replacing electricity, supplemented by plug-in, centralized charging and unified distribution. In other words, the development direction of state grid is to change power stations, not. In line with the above development ideas, State Grid also reserves advanced technologies such as battery balancing, battery automatic replacement equipment and battery cascade utilization. These forward-looking explorations and pre-research have laid a solid theoretical foundation for the budding electric vehicle industry, pointed out the general direction of technical development, and established the development path and ideological system of the whole industry. Today, these technologies have been widely used, especially the chassis replacement mode and standard battery box technology, which have become the mainstream of domestic electric vehicles. However, during 2013 -2014, State Grid did suspend the project of replacing new energy vehicles with electricity due to the change of the main task direction of enterprises. We inquired about the relevant historical information and found that apart from the change of the main tasks of enterprises, the irreconcilable contradiction with car companies is also one of the development factors that hinder their power exchange mode. After all, no car company is willing to become a subsidiary of State Grid. At that time, a director of the National Development and Reform Commission once said: "State Grid should put its position right and cooperate with car companies to develop electric vehicles with a more open attitude."However, State Grid’s insistence on the power exchange mode is not only not conducive to its stable position in the electric vehicle infrastructure market, but also more likely to restrict the development of electric vehicles. In other words, the failure to get through the industrial chain has become the biggest factor for the grounding of the State Grid’s power exchange model. On the other hand, the national policies at that time, such as subsidies and the environment of new energy vehicles, were still relatively weak. Therefore, although the State Grid ran through the business model of power exchange, it was unable to open up the industrial chain to form a business ecology due to institutional factors, and it was inevitable to suspend the power exchange project.

03-The sharing mode has no future.

After the State Grid froze the power exchange mode, Tesla, an American star company, demonstrated its 90-second quick exchange technology in 2013, once again detonating the problem of changing the phone all over the world, but soon Tesla will develop specifically for supercharger 3. From a technical point of view, Tesla still follows the chassis power exchange idea of Better place, but it is further improved in speed. But when "Iron Man" saw the fatal defect of chassis-type power exchange-abnormal batteries can not be shared across car models, and the compatibility of power exchange stations is low, so low compatibility can not improve operational efficiency. It is even more unrealistic to integrate the resources of car companies and form a common standard. In such a complicated power changing environment, Tesla silently quit to change the power stage.

The rise of 04 module box-splitting power exchange technology

In 2014, Nie Liang left the State Grid after seeing the possibility of opening up the industrial chain of the power exchange system and constructing the power exchange ecology. In the same year, Hangzhou Botan was established, and based on the power exchange of State Grid, the low-box standard box battery was further developed. Compared with the standard box of State Grid in 2010, the low-box standard box battery can be directly placed in the vehicle chassis (the original high-box standard box battery of State Grid needs to be placed under the back seat of the vehicle or in the trunk of the vehicle), and the stability and safety of the vehicle are greatly improved. On the other hand, at that time, the large-scale travel business began to exert its strength, and the market segment paid unprecedented attention to the operation economy of fuel and new energy vehicles. The split-box power exchange mode combined with the large-scale travel business perfectly solved the problems of operating costs and energy replenishment efficiency, and the module split-box power exchange ushered in its historical opportunity.

So, what is the principle of module splitting? First of all, the main dimensions of the TEU are completely the same, but according to the iteration of power battery technology, the energy density can be continuously improved. At present, the single TEU is mainly 15KWH (see the figure below). According to the requirements of vehicle models, different numbers of TEU power batteries are arranged on the vehicle chassis (2/4 for passenger cars and 6 or even 8 for logistics vehicles). Because the box size is the same at the initial stage of design, the power exchange station can exchange power for all vehicles using TEU, no matter which main engine factory they are made, thus completing the development of three limited power exchange modes: compatibility of power exchange equipment and vehicle models, compatibility of charging equipment with TEU, and recycling of circulating batteries.

05 Inventory of Power Exchange in China at the Present Stage

In 2016, the chassis replacement technology that sank for a period of time reappeared in the field of vision. This time, Cai Dongqing created Shanghai Aodong New Energy Automobile Technology Co., Ltd., and made continuous efforts in the power replacement business, and then quickly followed up. Sort out the development path of domestic power exchange technology, which is roughly as follows:

image.png

Mainstream power exchange technology: module splitting and chassis power exchange, as shown below:

image.png

It is worth noting that at present, the two modes of automatic route for power exchange are slightly different. Six-axis robots are mainly used for power exchange in modules, and RGV is mainly used for chassis change, which is roughly as follows.

image.png

Market application: Beiqi Weilai Xinchufeng is used for chassis power exchange, Dongfeng, Zotye, Universiade are used for module power exchange, and the number of vehicles put in and the actual mileage of operation are slightly superior.

How to compare the above two power exchange technologies?

We believe that it is not objective enough to compare the above two power exchange technologies only from the actual promotion layout level (such as infrastructure investment, power exchange capacity, site requirements and construction speed, etc.). The reason for this is the following:

Equipment level: manual, semi-automatic or full-automatic power exchange mode can also be selected for box-by-box power exchange, and the investment intensity can be selected according to the actual situation, while chassis power exchange can only be fully automatic, so it has higher capital requirements and limited investment flexibility in practical promotion. However, according to the fully automatic standard, the cost difference between RGV and six-axis robot equipment is not big.

Site expansion level: the chassis can be quickly laid out in containers for power exchange, and the landing speed is slightly faster, but some cities are not allowed to work in containers (such as Guangzhou). Therefore, in terms of policy compliance, the requirements for the construction of sub-box power exchange and chassis power exchange are basically the same.

On the aspect of power exchange capacity: in the fully automatic state, the average daily power exchange capacity can reach about 250 times with little difference. However, there is a point of concern in this respect. According to the public data, although there are more charging compartments in the power exchange stations with the same power exchange capacity, the number of vehicles that can be exchanged for electricity is only slightly more or equal to that of the chassis (we think that the future evaluation of power exchange capacity can not only rely on the single angle of power exchange speed, because the power exchange capacity depends on the number of charging compartments in the station energy supply, From this point of view, the general modular sub-box power station has 120 cells at the same level, while the chassis power station has 28 cells. However, one car in the modular sub-box power station consumes 4 cells on average, so the power exchange capacity of 120 cells, that is, 30 cars at a time, is not much different from that of the whole pad chassis power station with 28 cells. Therefore, there is little or no difference between the two modes from the above three aspects, so there is no way to compare them only from these three points.

With the issuance of the document "Implementation Plan for Promoting the Updating and Upgrading of Key Consumer Goods and Smooth Resource Recycling (2019-2020)", on the basis of encouraging the development of power exchange mode, requirements are put forward for battery modularization and step utilization of batteries. Therefore, which mode can be compatible with more types of vehicles, better connect the front and rear ends of battery step utilization and better adapt to the future modular development of automobile manufacturing is the more important focus.

From the perspective of vehicle compatibility, the power exchange mode should not be a limited energy supplement scene in the end, but an open source energy supplement mode, because the most basic and basic construction purpose of the power exchange station is to be used as a public infrastructure to facilitate public travel, otherwise why do you enjoy subsidies? At present, Beiqi, Weilai and other car companies are leading the chassis power exchange, because the batteries of their respective car companies are opposite-sex batteries compared with other OEMs, the power exchange sites or batteries cannot be universal. However, Dongfeng, Universiade, Zotye and other enterprises adopt the idea of modular box-splitting power exchange based on standard box batteries, which makes the power exchange station shared among different car models, and the battery can be shared, which greatly improves the utilization ratio of the site and the battery. Therefore, from this perspective, it is obvious that modular box-splitting power exchange is more suitable for the current concept of "sharing economy" and is also an intensive use of social resources.

From the point of view of power battery recycling, the mainstream design ideas in the industry at present are as follows

image.png

Direct view of step utilization of power battery

From the point of view of echelon utilization, we must first reduce the transformation cost in the process of each degradation, otherwise it will be difficult to land. From the top-level design point of view, the standard of battery should be unified first, and then the battery with smaller relative weight and volume (because it can’t be directly used in section B and section C if it still stays in the direction of the overall special-shaped battery of most models at this stage). Only under these two preconditions can the whole life cycle development of battery be maximized, and the average use cost of power battery at the user’s end will be lower.

Therefore, from the perspective of battery recycling, it is obvious that the case-by-case power exchange built by the standard box system is more in line with the policy and national conditions. However, from the perspective of automobile enterprises, the whole chassis-type power exchange has less changes to the chassis of the whole vehicle body, and the technical level is relatively easier to realize; However, the modular box-changing technology requires higher requirements for body chassis modification and design cycle. However, it is very interesting that the number of car companies that accept the standard box-splitting power exchange system is far more than that of the chassis-type power exchange model (the total number of cars that are actually put in the box-splitting power exchange system is also more than that of the chassis-type power exchange system). It can be said that many car manufacturers are doing power exchange, and obviously many car companies do not want to play with tickets at this level, but stand higher and look farther.

07 written at the end

On June 5, 2016, China Tower established an energy company with a capital of 5 billion yuan to take the lead in entering the terminal market of power battery ladder utilization, which made it possible for standard box batteries used by modular box-changing electric vehicles and power-changing technology companies to be used in large-scale terminals (compared with special-shaped batteries). The integrity of power battery ladder utilization has been further improved, while the extension of battery ladder utilization industrial chain has further reduced the average use cost of power batteries, which will indirectly reduce the consumption cost of new energy vehicles. From the perspective of industrial chain, does it mean modularity?

We gave time to this problem, but for enterprises that insisted on changing electricity in the early stage, in June 2019, the wind started.

How is the implementation of climate commitment actions in countries near the global climate summit?

  In 2023, frequent extreme weather and climate events once again left a deep impression on people. In China, sandstorms in the northwest, droughts in the southwest, extreme rainstorms in North China and typhoons in South China have all brought rare disasters in recent years. On a global scale, forest fires in Canada, alternating droughts and floods in the United States and India, high temperatures in Europe, and heavy casualties caused by hurricanes in the Mediterranean have also caused shocking consequences.

  Reality warns people that the negative consequences of climate change are increasing with the rising temperature. At the end of November this year, world leaders will gather in Dubai, United Arab Emirates, to attend the 28th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP28). People hope that this meeting will achieve more results and create more favorable conditions for the global response to climate change. We should not only pay attention to the set ultimate goal, but also find feasible paths and effective ways to promote it.

  On December 12, 2015, in order to cope with the increasingly serious climate change problem, nearly 200 parties to the United Nations Framework Convention on Climate Change unanimously agreed to adopt TheParis Agreement at the Paris Climate Change Conference to make arrangements for global action to deal with climate change after 2020. At this year’s COP28 conference, all parties will conduct the first global inventory since the Paris Agreement.

  On September 8th, the report on the inventory results released by the United Nations showed the progress made since the Paris Summit in 2015, and pointed out that compared with the prediction made in 2010 that the global temperature would rise by 3.7-4.8 degrees Celsius by the end of this century, the predicted temperature rise is now 2.4-2.6 degrees Celsius, but it still far exceeds the goal of controlling the temperature at 2 degrees Celsius and trying to control it within 1.5 degrees Celsius.

  At the same time, the report clearly pointed out that all parties need to respond to climate change in an all-round way with higher ambition and a stronger sense of urgency. At present, global greenhouse gas emissions are still increasing, and to achieve the above goals, global greenhouse gas emissions need to be reduced by 43% compared with 2019 levels by 2030 and 60% by 2035.

  On the occasion of the upcoming global climate conference, The Paper’s Critical Point combed the climate commitment actions of some major countries in the world. In response to climate change, our window of time and opportunity is shrinking rapidly.

  United States of America

  It has been six months since the United States resumed its contribution to the United Nations Green Climate Fund (GCF) and allocated a new $1 billion. Rich countries, including the United States, have not yet fulfilled their climate funding commitments, and developing countries are facing the fact that the speed at which funds are put in place is far behind the increasingly severe extreme weather and climate events.

  According to British media reports, on October 21 this year, the negotiations on implementing the "loss and damage fund" first proposed at last year’s UN Climate Conference to help countries with fragile climate rebuild their homes reached an impasse. The United States and the European Union proposed that the World Bank should host the fund. However, questa, Chairman of the Group of 77, believes that the effectiveness of the World Bank’s decision-making is difficult to cope with the climate crisis. In addition, if the fund must operate within the legal structure of the World Bank, the wider sources of funds may be limited.

  Not only is the operation of funds stagnant, but the amount of funds raised at present is still insufficient for the reconstruction of countries with fragile climate. According to American media reports on October 6, at the donor conference held in Bonn, Germany, developed countries promised to provide 9.3 billion US dollars to supplement green climate funds. However, NGOs believe that these funds are not enough to help countries with fragile climate to cope with climate change. It is worth noting that the United States is one of the few developed countries that have not provided new funds.

  Nine years ago, the United States promised to provide $3 billion to the Green Climate Fund, but so far it has only injected $2 billion. Of the $11.4 billion pledged by US President Biden to developing countries, the country’s Congress only approved $1 billion. In fact, as early as the 15th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP15) held in Copenhagen in 2009, the United States and other rich countries promised to raise 100 billion dollars annually for climate action in developing countries by 2020. This goal was reaffirmed at COP21 in Paris and extended to 2025. According to reports, the current funding gap is as high as $17 billion per year.

  Fossil fuel subsidies are still soaring, despite the delays in climate finance in rich countries. According to the global regulatory organization Energy Policy Tracker, the public funds flowing to fossil fuels in G20 countries will reach a record $1.4 trillion, more than double the amount before the COVID-19 outbreak in 2019.

  Restricted by domestic social contradictions and inflation, it is difficult to cancel fossil fuel subsidies in the United States. In the United States, the Supreme Court, which has been dominated by the Republican Party for a long time, keeps opening the floodgates of money politics for the wealthy class. The accumulated polarization between the rich and the poor has laid the groundwork for the social phenomenon that high oil prices are often accompanied by a decline in the support rate of presidential polls. On the other hand, unlike other countries, subsidies in the United States are mainly tax relief for fossil fuel companies, that is, by providing credit and expense deduction to energy producers to reduce production costs.

  Saudi Arabia

  Under the pressure of decarbonization, Saudi Arabia, the world’s largest crude oil exporter, launched a comprehensive action to deal with climate change and reduce carbon emissions in 2021 to reduce domestic carbon emissions, including achieving "net zero" greenhouse gas emissions by 2060, planting 50 billion trees in the Middle East in the next few decades, and launching a $10.4 billion clean energy project for the region.

  However, according to the Financial Times reported on July 23rd, several countries, led by Saudi Arabia, tried their best to stop G20′ s call to reduce the use of fossil fuels. At the same time, Reuters reported that Saudi Arabia and other countries opposed G20′ s proposal to triple renewable energy production capacity by 2030. Saudi Aramco announced in 2021 that it plans to increase crude oil production from 12 million barrels per day to 13 million barrels per day by 2027. According to Agence France-Presse, the total profit announced by Saudi Aramco in 2022 reached a record $161.1 billion.

  Reduce the burning of fossil fuels at home, so that Saudi Arabia can free up more oil to sell abroad. In this regard, Saudi Arabia attempts to explain the rationality of this contradiction by implementing the "circular carbon economy" plan, which envisages continuing to exploit fossil fuels and adopting new technologies to capture, store or sell carbon emissions. At the same time, according to media reports, Saudi Arabia and other traditional fossil energy countries believe that it is unrealistic to tighten the "faucet" of fossil fuels immediately, and hydrocarbons such as oil, natural gas and coal will continue to become an important part of the global energy structure in the next few decades.

  Saudi Arabia regards tackling climate change as a long challenge, but the International Energy Agency (IEA) released a report in May 2021, saying that if the world wants to achieve zero carbon emissions by 2050, governments and enterprises of all countries must immediately stop investing in new oil and gas projects. The unresolved issue is also the "carbon capture" technology promoted by Saudi Arabia — — The effectiveness of this technology has not been proved, and the cost of applying it to large-scale mining is too high.

  "It is believed that the economy based on the exploitation and combustion of fossil fuels can be ‘ Loop ’ The idea is absurd, and the only way it works is to rely on technologies that don’t exist yet. " Matthew Archer, a researcher at the Geneva Institute, said in an interview with the media, "These measures … are full of ambitious and ambiguous language, with few specific plans and no accountability mechanism."

  Japan

  Coincidentally, Japan’s climate solution is also questioned. According to local media reports, on September 29th, Japan hosted the 3rd International Fuel Ammonia Conference, which focused on the theme of decarbonization of supply chain and shipping industry. This meeting is a sign of Japan’s commitment to a climate solution, but some experts believe that the solution may not meet the world timetable that urgently needs to reduce carbon emissions.

  Consistent with all countries, Japan urgently needs to decarbonize the energy sector. At present, Japan plans to reduce the energy share of coal to 19% by 2030. At the meeting, the government and major industries described the vision of using ammonia (a gas composed of nitrogen and hydrogen) on a large scale in the foreseeable future, that is, reducing carbon dioxide emissions from coal-fired power plants by replacing fossil fuels with ammonia. Because ammonia combustion will not emit carbon dioxide, and the co-combustion equipment of existing coal-fired power plants in Japan does not need major transformation.

  From a technical point of view, it seems feasible to burn ammonia to generate electricity. "Japan Times" reported on October 22nd that JERA, Japan’s largest power company, is testing the 20:80 ammonia-coal co-combustion ratio at Binan Thermal Power Station in Aichi Prefecture, Japan. It is reported that JERA’s goal is to gradually increase the proportion of ammonia-coal mixed combustion and realize 100% ammonia combustion by 2050.

  However, with the government and enterprises eager to establish an ammonia fuel supply chain on a global scale, experts began to question the feasibility of ammonia as a decarbonization solution in Japan. Although ammonia will not emit carbon dioxide when it is fully burned, fossil fuel is an essential raw material for ammonia production.

  In this regard, many Japanese power companies, including Mitsui & Co., Ltd., are exploring a new mode of ammonia production, that is, using fossil fuels to produce ammonia, and at the same time capturing 80%-90% of carbon emissions through CCS technology. Considering the high price and poor performance of CCS technology at present, some ongoing ammonia synthesis projects focus on developing technologies to produce ammonia through renewable energy. However, Motoichi Kato, deputy secretary-general of Japan Clean Fuel Ammonia Association (CFAA), told the media that all ammonia imported from Japan is still produced by traditional production methods, and the new ammonia production technology has not yet covered the whole world.

  In addition to concerns about carbon emissions caused by ammonia production procedures, experts also said that producing such a large amount of ammonia may pollute the air and water quality. According to the Japan Times, Japan is expected to need 3 million tons of ammonia by 2030 and 30 million tons by 2050. Climate Integrate, an independent climate policy think tank in Japan, warned that fixing nitrogen from the atmosphere to produce ammonia may further disrupt the balance of the global nitrogen cycle. In addition, the increase of nitrogen will lead to eutrophication of marine ecosystem, as well as air pollution and groundwater pollution.

  South Korea

  Compared with the above countries, South Korea has not performed well in dealing with climate change in recent years. According to the report updated by Climate Action Tracker on July 17, 2023, the overall rating of South Korea’s actions to deal with climate change is classified as "seriously inadequate". Furthermore, South Korea’s climate policy and energy sector planning still lack the necessary speed and rigor, and can not embark on the road that conforms to the temperature limit of 1.5°C in the Paris Agreement.

  After the change of government in South Korea in 2022, the country’s climate policy changed, deviating from the 100% renewable energy target previously set by the government. The new president Yin Xiyue publicly stated that the target was "too expensive". According to media reports, on March 21st this year, South Korea announced that it would lower the greenhouse gas emission target of the industrial sector in 2030. According to the plan, the Korean industrial sector is required to reduce carbon emissions by 11.4% compared with 2018 levels by 2030, while the emission reduction target set by the end of 2021 is 14.5%.

  According to the plan, the carbon emission gap caused by the adjustment will be made up by increasing emission reduction overseas and replacing traditional energy with more renewable energy. However, given that South Korea has reneged on its climate commitments, the way to make up for the plan is still in doubt. According to the Climate Action Tracking Agency, in April 2021, South Korea announced at the leaders’ climate summit hosted by the United States that it would immediately stop providing financing for overseas coal projects. Just one month later, it announced the exception of renovation and approval of related projects.

  On the other hand, Yin Xiyue decided to revive the nuclear power plan, overturning the previous president’s reform of phasing out nuclear power. It is reported that the Korean government promulgated the tenth power plan in January 2023, aiming at using nuclear energy to realize national decarbonization. Contrary to the original goal of limiting the proportion of nuclear energy to 30% by 2030, the latest goal is to increase the proportion of nuclear energy use to 34.6%.

  In January 2012, South Korea promulgated the Renewable Energy Portfolio Standard (RPS). According to the International Energy Agency, the plan aims to expand the use of renewable energy and make it a promising market competitor. To this end, the 13 largest Korean power companies are required to increase the use of renewable energy to 14.5% and 17% in 2023 and 2024 respectively, and to reach 25% after 2026. However, according to Yonhap News Agency’s report on January 13th, 2023, the South Korean government lowered the RPS target for this year and next to 13% and 13.5% respectively, and the final goal was postponed until after 2030.

  Canada

  Countries that have failed to say what they must do in climate action include Canada. According to the Canadian Broadcasting Corporation (CBC), since 1990, the country has formulated nine climate plans, but failed to achieve the goals.

  Even though Canadian Prime Minister Justin Trudeau released a comprehensive emission reduction plan for 2030 on March 29th, 2022, listing a series of actions that the country will take to reduce climate pollution to 40% to 45% lower than the 2005 level by the end of this century, the plan still has many defects.

  For example, the plan does not provide enough funds to help automobile suppliers increase the sales of electric vehicles according to the government’s goals. Secondly, there are criticisms that the goal is to reduce the climate pollution of the energy industry without limiting production, which will require fossil fuel companies to make great improvements in carbon capture technology.

  In addition, a report on April 24th said that a recent study published in the Proceedings of the National Academy of Sciences showed that the Canadian government and enterprises seriously underestimated the current domestic carbon emissions.

  Britain

  Backward climate action may also affect the activity of other countries in the field of climate governance. According to media reports on September 20th, British Prime Minister Sunak may dilute Britain’s plan to deal with climate change, including postponing the ban on the sale of new gasoline and diesel vehicles originally scheduled to take effect in 2030, greatly weakening the plan to phase out gas boilers by 2035, and not updating the energy efficiency regulations for housing construction.

  Sunak said that he is still committed to the legally binding goal of achieving net zero emissions by 2050. At the same time, he also said that Britain can slow down its progress in achieving this goal because Britain is "far ahead of all other countries in the world." However, considering the national election in 2024, Reuters in the United Kingdom believes that Sunak leaked the news of reducing the green policy in order to gain the support of voters who are troubled by high inflation and stagnant economic growth.

  Britain is the first country to set a legally binding "net zero" goal in 2050. Since 1990, with the closure of coal-fired power plants and the rise of offshore wind power, the country’s carbon emissions have dropped by nearly 50%. However, according to media reports on September 21st, the British government’s independent climate adviser said that Britain still has some shortcomings in achieving its climate goals, and diluting its plan to deal with climate change may further weaken its ability to fulfill its legal commitments.

Mathematics education in the swing of primary school is easy to advance and middle school is difficult to swing.

  Ma Jia is a teacher majoring in mathematics in a university in Beijing. This summer, he enrolled his daughter Ma Lu in a 12-day math extracurricular class. "In her daughter’s words, the most difficult questions in the extracurricular class are also simpler than the simplest ones she usually does at school." However, Ma Jia still insisted on letting her daughter go to this extracurricular class. "The mathematics learned at school is too difficult, so let the children find the confidence to do the problem here."

  Ma Lu is studying in a good middle school, and the second day of junior high school is about to begin. This school is yearning for many parents because of its "difficult study" and "good grades in the senior high school entrance examination".

  While attending classes in Ma Lu, in the adjacent classroom, Tao Qian, who just finished "Xiaoshengchu", was also attending math classes. "Many parents told me that math in primary schools is too simple. If I don’t study in the summer vacation, I can’t keep up with school." Tao Qian’s mother told the reporter of China Youth Daily and China Youth Network.

  Same math, different troubles.

  In fact, the troubles brought by mathematics to Chinese people in these years are by no means just these.

  A few years ago, at the craziest time of choosing a school in junior high school, Olympiad was the most powerful "weapon" in choosing a school, so that many children were miserable when they learned it.

  Later, the Olympiad became a "monster" and was banned again and again. Mathematics was also in the voice of reducing the burden and has been reducing the difficulty.

  What followed was that China students’ scenery in the International Mathematical Olympiad was no longer there, and the champion who had won for many years was lost for four years.

  Just as people questioned whether the difficulty of mathematics had dropped too much, just after the college entrance examination and senior high school entrance examination this year, there were media reports that the candidates were crying outside the examination room because the questions were too difficult.

  Is mathematics difficult or easy? Should mathematics be more difficult or easier?

  Some people say that China’s mathematics education has been swinging in recent years, and this swing seems to be unique to China: when a group of people shout "too easy", we seem to think that mathematics is easy and should be more difficult; When another group of people shouted "It’s too difficult", we seemed to think that mathematics was difficult and were busy reducing the difficulty.

  On July 12th this year, the Ministry of Science and Technology, the Ministry of Education, the Chinese Academy of Sciences and the Natural Science Foundation of China jointly issued the "Work Plan on Strengthening Mathematical Science Research" (hereinafter referred to as the "Plan"), calling for strengthening mathematical science research and continuously and stably supporting basic mathematical science.

  It is mentioned in the Plan that the strength of mathematics often affects the strength of a country, and almost all major discoveries are related to the development and progress of mathematics, which has become an indispensable and important support in the fields of aerospace, national defense security, biomedicine, information, energy, ocean, artificial intelligence, advanced manufacturing and so on.

  The release of the document has played a decisive role in mathematics teaching, and some essential problems should be discussed more fully: how should mathematics education in primary and secondary schools develop? Can the swing from easy to difficult stop? The reporter of China Youth Daily and China Youth Network recently interviewed many experts in the industry, trying to make a more rational analysis of the current mathematics education in primary and secondary schools.

  "shallow enough to make people want to cry"

  Primary school mathematics is caught in the form of operation and visualization.

  "I always emphasize that primary school mathematics must not be too operational and intuitive, and students should learn to think and recall problems." Liu Jiaxia, dean of the School of Primary Education of Beijing Institute of Education, said.

  At one time, mathematics education in primary and secondary schools in China was famous for its difficulty. Many people may still remember the classic example: when an American adult is asked what 7×8 is, they will be very embarrassed to answer, "I’ll look for a calculator." And the same question, China grade two or three primary school students will basically blurt out.

  While people are proud of China’s children’s solid mathematical foundation, they are also thinking about how memorizing the multiplication table of 1999 can really help a child’s mathematical study.

  Some experts pointed out that mathematics learning should go through romantic period, accurate period and comprehensive period, while primary school learning is in romantic period, so that children can play and go to school.

  As a result, in many places, primary school mathematics has not only increased the content of practical operation, but also the exams in the lower grades of primary schools have become a "music test". Many years ago, the exercises such as oral arithmetic competition and calculating the standard for 100 days have become rare.

  "But in fact, this ‘ Play and learn ’ It is a higher realm, and the requirements for teachers are higher. " Liu Jiaxia said that not all grades of study must be ‘ Play and learn ’ , and not all knowledge is suitable for ‘ Play and learn ’ . Especially in the middle and senior grades of primary schools, we should not only operate and be intuitive, but also have reasoning, and some rational methods and training should keep up. "Although it is necessary for middle schools to reflect on refining the law after doing the questions, there will be difficulties in the connection of middle schools if there is no relevant training at all in the primary school stage."

  Not long ago, there was a post on the Internet that caused a heated discussion. A teacher left homework in the parents’ WeChat group, saying: One of the math homework in the evening is hundreds of millions of grains of rice, so parents can urge their students to finish it and take it to school in food bags the next day. The group of parents immediately exploded. Some said, "If one grain counts, it will take a year." Some said, "Is this a brain teaser?" Others asked, "How can I get to school tomorrow?".

  Although the case of hundreds of millions of grains of rice is too wonderful, the situation of being too formal and operating for the sake of operation can be seen everywhere in today’s primary school mathematics classroom.

  Teacher Liu Jiaxia introduced that once she went to a division class in primary school. The example given by the teacher in class is 24÷2, which means that 24 is divided into two parts on average. How to divide it? The teacher led the students to divide the sticks, first one by one, then two by two, and then continue to divide them. "If you are a sophomore, this division is still meaningful, but the real difficulty in this class is the vertical division. This division is completely for the sake of division and operation." Liu Jiaxia said that the teacher should directly present: "two bundles of four", two bundles are two tens, and there are four left, and divide the "two bundles of four" equally. At this time, the children should be led to discuss why they should be divided into high positions first (that is, "bundles"), and then the high positions will be divided into low positions.

  "Elementary school mathematics is so shallow that people want to cry." A primary school math teacher said that sometimes it is even required to teach students no more than two steps to solve problems.

  Teacher Liu Jiaxia introduced that primary school students often use the "staring method" to solve problems: there is no need to draw pictures, discuss or question, and the answer is unique. There are only two steps at most, and you can know the answer by staring. "In fact, primary school mathematics should be easier to test, but it is slightly more difficult to learn. The difficulty is not to increase the difficulty of knowledge, but to expand students’ knowledge, to be more reasonable, and to tell the stories behind mathematics knowledge." Liu Jiaxia said, but now there is too much emphasis on operation and intuition, which makes many primary school math classes like teachers coaxing children to play.

  不过有时候也不仅是老师哄着学生玩,学生也哄着老师玩。

  “我们在实际教学中还有一个矛盾。”北京某小学的数学牛老师说,学习内容虽然简单,但是对老师的课堂教学过程还要求多样化。“我们经常在课堂上问:孩子们谁还有别的方法?谁还有问题?但这其实低估了孩子的智商,学习内容这么简单还能有多少方法?还能提出多少问题?”牛老师说,久而久之,学生们便配合着老师一起演。

  老师哄着学生、学生哄着老师,学校里的学习氛围变得轻松了,这种轻松既无法满足聪明孩子的求知欲,同时也无法满足中国家长“不输在起跑线上”的期望,于是“不满足”的家长带着“吃不饱”的孩子进了课外班。

  初一学初二的课程

  超前学让中学数学陷入刷题的汪洋大海

  小学阶段的数学太容易了,浪费了学生的智力。那么,中学呢?

  有人说在中国最苦的学生就是中学生,因此最应该给中学生减负。

  Many people feel that it is difficult to learn, so the burden is heavy, so to reduce the burden, we should reduce the difficulty. "There is actually no relationship between burden reduction and difficulty." Professor Zhao Xuezhi from the School of Mathematical Sciences of Capital Normal University said.

  Today, great changes have taken place in the content of mathematics learning, and at the same time, the methods of mathematics have also changed. This change itself may bring a burden to students. "For example, we used to use derivation to do geometry problems, but now we will use vectors." Zhao Xuezhi said that vector has been debated by math teachers since the day it was introduced. Many people think that the introduction of vector destroys the joy that geometry brings to students when they finally draw a wonderful auxiliary line after trying to break their heads. Others regard the introduction of vectors as evidence that mathematics has reduced the difficulty.

  "In fact, it is difficult to make a simple summary with difficulty." Zhao Xuezhi said that just like walking the same road, people used to walk, but later they changed to take a bus. Originally, walking and taking a bus would not add extra burden to people. But if you go out for a while and then drive back, then go and drive again, the burden will be heavy.

  Experts pointed out that these problems encountered in the development of mathematics will disappear with the skilled use of tools and methods. In middle school, what really causes students’ heavy burden of mathematics learning is not the difficulty, but the advance — — That is to say, when teachers and students are not ready, they are in a hurry to catch up with the progress, which often causes teachers not to pay attention to the teaching process, while students are eating raw rice.

  Ma Lu, who started school in Grade Two, began to learn the content of Grade Two in the next semester of Grade One. Ma Lu said that just because what she learned in school was fast and difficult, she had to "return to the furnace" in the extracurricular class during the summer vacation.

  Learning ahead of time has become a very common phenomenon in middle school mathematics learning.

  What knowledge is learned at what age is suitable for students’ cognitive characteristics at this stage. Learning ahead means that what they have learned is beyond students’ cognitive ability. In order to let students master knowledge, teachers usually practice a lot.

  "Let’s take a simple example to see the relationship between learning ahead and the burden." Professor Zhao Xuezhi said that if we teach at an age consistent with students’ cognitive level, we only need to make it clear that 2 is bigger than 1, and then students can draw countless groups of comparisons by analogy. However, if students learn ahead of time, they can’t understand the relationship between comparisons. In order to let students master this knowledge, teachers will let students remember that 2 is bigger than 1, 3 is bigger than 2, and 4 is bigger than 3 … … "Exhausted and remember, this process is a process of massive practice. Can the burden on students be small?"

  在这个过程中,数学教学培养的是学生的记忆力,而不是推断力。“数学的学习关键是掌握了原理,然后举一反三,而不在于你记住了哪些具体的知识。”赵学志说。

  但是,在当前的很多中学,中考和高考分数仍然是教学的主要奋斗目标,在这种前提下老师们不是以更多的精力引导学生进行更多的思考,而是总结题型,追求题型的全覆盖,进而把学生扔进刷题的汪洋大海。学生的思辨能力、推理能力自然无法得到很好的训练。

  今年高考之后,考生们被“难哭了一片”,很多人不禁怀疑:难道数学的难度又要提高了吗?其实,高考数学科目刚刚结束,教育部考试中心的命题专家就指出,2019年的数学试卷,在难度、区分度上都与前两年相当,只是更加强调考查学生的理性思维能力,综合运用数学思维方法分析问题、解决问题的能力。

  The proposition expert specifically mentioned the Venus that made the candidates "frightened" and pointed out that this question is not to be difficult for students, but to "explore the beauty of the golden section of the human body and integrate aesthetic education into mathematics education." When the candidates calmed down and looked at this "Venus" again, they finally understood that "Venus" was only a narrative way of the topic, and the real mathematical knowledge had probably been learned in the sixth grade of primary school.

  The difficulty of the college entrance examination has not increased, but the flexibility has increased, and the students who are tired of brushing the questions are at a loss.

  Many experts pointed out that there is nothing wrong with the reform direction of mathematics education, and there is nothing wrong with reducing students’ burden. The crux of the problem is that professional things have not been entrusted to professional people.

  An expert said that people will always mention the difficulty coefficient now, but in fact, the difficulty coefficient is an indicator of post-verification, and it is a monitoring indicator for the education management department to maintain the stability of the exam for a long time. "We don’t need to monitor the difficulty coefficient like monitoring blood sugar at all." Zhao Xuezhi said that the whole society and even ordinary people are concerned about talking about this coefficient, which can only increase anxiety, and it is easy to misread the changes of numbers, which in turn leads to unnecessary misunderstanding of mathematics education.

  An expert suggested that the reform should be handed over to the education management department and teachers should be liberated from daily affairs, so that the mathematics classroom can return to rationality and mathematics can return to its original appearance. (Reporter Fan Weichen)

Just look at the domestic ones! The most beautiful 7 2.1 speakers in history

    Bubble net Audio Channel on June 6th. From the birth of the first innovative 2.1 speaker PCWorks 2.1 to now, the multimedia speaker industry in China has developed for more than ten years. It can be said that while people are demanding more and more sound, they are also very picky about the appearance of products. Wood veneer, piano paint, wire drawing and other technologies are integrated into the products, resulting in a variety of design styles.


    Note: The "domestic" mentioned by the author in the title refers to the domestic multimedia speaker market, not domestic brands, and does not include high-end audio.



Innovating the first 2.1 speaker PCWorks 2.1


◎ Tips


    PCWorks was originally a subsidiary of Creative in the United States, a sub-brand of multimedia speakers of CambrIDE SoundWorks, a famous Hi-Fi factory. PCWorks speakers were designed by the Emmy Award winner, a world audio authority, and entered the China market in 1997. At that time, PCWorks 2.1 was the first to introduce the concept of X.1 speakers, and the application of independent subwoofers greatly improved the sound quality of speakers.


    In these years, how many products have left a deep impression on us with novel designs? If you want to know the answer, let’s take a look at the most beautiful speakers selected by the author in the domestic multimedia speaker market.


● Generation V6cs


    Appearance innovation: ★★★★
    Word of mouth evaluation: ★★★★★
    Comprehensive evaluation: ★★★★☆.


    Generation V6cs, this speaker impacted the domestic multimedia speaker market at the price of around 500 yuan in 2005, which brought unprecedented pressure to 2.1 speakers. Its unique styling design and excellent sound quality performance have so far made many users forget it.



Generation V6cs



Generation V6cs


    The subwoofer of this era V6cs speaker is the highlight of this speaker. The front panel of the subwoofer is designed with a butterfly-shaped metal baffle and is convex. Inside the subwoofer is a 6-inch long-stroke bass unit, and there is an orange power lamp below, which can emit faint light through the front baffle to make the finishing touch.


    In terms of satellite box, this speaker uses a 3-inch full-frequency antimagnetic unit, which was a model that was used more in the generation of speakers at that time. There is also a passive unit behind the satellite box, which lays the foundation for improving the overall sound quality.


● Grand Pole A6


    Appearance innovation: ★★★★★
    Word of mouth evaluation: ★★★★★
    Comprehensive evaluation: ★★★★★


    In the early years, Taiji Dian was also a leader in the multimedia speaker market in China. Later, with the development, they gradually moved closer to the professional field and separated from the ordinary consumer groups. However, we have to admit the success of the A6 2.1 multimedia speaker of Dajidian.



Dajidian A6


    The A6 speaker of this grand classic adopts the design of vacuum tube preamplifier, which satisfies the users who have high requirements on dynamics and sound quality. From the modeling point of view, it is even better than the previous generation V6cs, with a unique metal panel and a black piano paint box on both sides, all of which make the Grand Pole A6 not lose to any 2.1 multimedia speaker sold at that time.


    In addition to the characteristics of half the multimedia speakers, we can see a unique feature in this grand classic A6, that is, there is a control called "phase switch" on the back of the speaker, which can only be seen on high-end audio. However, for the first time, Taiji Dian introduced this concept into multimedia speakers, which inadvertently became the focus at that time.


● hivi T120


    Appearance innovation: ★★★★★
    Word of mouth evaluation: ★★★★★☆.
    Comprehensive evaluation: ★★★★★☆.


    Hivi can be said to enjoy a high evaluation in the domestic multimedia speaker industry, and is also sought after by HiFi people. In hivi 2.1 speaker products, it must be T120 to talk about "looks". At that time, it seemed that the triangular section panel design was the focus of attention unconsciously.



Hivi T120


    Hivi T120 speaker was priced at more than 900 yuan when it was listed at that time, and the overall workmanship and sound quality of the speaker were unquestionable, which was well received by consumers.

Global Digital Governance | Trends of Global Digital Competitiveness in 2021

The long-delayed COVID-19 epidemic has once again highlighted the indispensable and extensive influence of digital technology on a global scale. The rise of new technologies such as artificial intelligence, Internet of Things, 3D printing, augmented reality and virtual reality, and quantum computing is subverting the traditional economic and social operation mode and shaping new development opportunities. How a country responds to the various changes brought about by the technological revolution and establishes corresponding competitiveness around digital technology will not only determine its future economic growth, but also affect its geopolitical status. In this context, countries all over the world have put the digital transformation in the fields of economy, governance and life into the important agenda of the government, and increased resource input and policy support to improve their digital competitiveness.

Not long ago, the European Center for Digital Competitiveness of the European Advanced Business School (ESCP) released the Report on the Promotion of Global Digital Competitiveness in 2021 (Digital Riser Report 2021)。 The research report comprehensively uses the relevant data from the World Economic Forum, the World Bank and the International Telecommunication Union to evaluate and rank the current digital competitiveness of 137 countries around the world, and extracts the best practices of countries with rapidly rising digital competitiveness, so as to provide decision-making and action guidance for other countries. The relevant research conclusions have certain reference significance for countries around the world to understand the advantages and disadvantages of their digital transformation from a macro perspective and to calibrate the strategic direction of enhancing digital competitiveness.

The research report simplifies the definition of a country’s "digital competitiveness" as 10 equal weight factors in two categories: "digital ecosystem" and "digital thinking mode", and divides all countries into nine groups, namely, G7, G20 and Asia-Pacific, Eurasia, Europe and North America, Latin America and the Caribbean, Middle East and North Africa, South Asia and sub-Saharan Africa defined by the World Economic Forum. On this basis, combined with the data of the three years from 2019 to 2021, it is scored and ranked. Among them, the elements belonging to the "digital ecosystem" include the difficulty of obtaining venture capital, the cost of starting a business, the time required for starting a business, the convenience of hiring international talents, and the digital skills of university graduates; The "digital thinking mode" includes the digital skills of the working population, the attitude towards entrepreneurial risks, the diversity of labor force, the scale of mobile broadband users, and the acceptance of subversive business development ideas by enterprises. The scoring results intuitively reflect the changes of digital competitiveness of countries in terms of sub-items and overall, while limiting the ranking to nine groups is to ensure that the comparison baseline is relatively fair and the results are comparable. By combing the relevant evaluation results, the report puts forward three main findings:

Nowadays, the global digital competitiveness is changing.

The research report shows that while the digital competitiveness of some countries and regions is rapidly improving, some leading digital countries in public perception are gradually losing their advantages. Taking China and the United States as two digital superpowers, for example, during 2019-2021, China’s digital competitiveness improved obviously (+211), while the United States showed a decline (-72). Moreover, whether in the G7 or G20 group, the ranking of the increase in digital competitiveness of the United States is in a relatively backward position. The analysis believes that the decline of digital competitiveness in the United States is mainly driven by the dimension of digital ecosystem, including a series of adverse effects such as increasing immigration and visa barriers, which makes it more difficult to attract international digital and information professionals. The promotion of China’s competitiveness is mainly reflected in its strong advantages in the dimension of digital thinking mode, including the proposal and deployment of a series of national overall strategic plans, and taking scientific and technological innovation and entrepreneurship as important measures to achieve high-quality development.

In addition to the United States, Britain (-85), Sweden (-92) and other developed countries in digital technology also failed to show a significant increase in digital competitiveness. India (-396), Germany (-176) and other big countries even experienced a sharp decline in competitiveness in both digital ecosystems and digital thinking modes. However, some countries, such as Georgia (+153), Egypt (+258), Canada (+47) and Vietnam (+339), which do not have a high digital starting point, have become the leaders in this field because they have implemented a series of fruitful digital transformation measures. To some extent, this shows that the global digital competitiveness pattern is in the process of dynamic reorganization, and new global digital technology leaders will appear in the future.

Digital competitiveness is closely related to digital transformation measures.

The research report collects the "Best Practice" of digital transformation in G7, G20 and seven regional economic groups whose digital competitiveness has increased significantly in the past three years, covering the actual progress in the fields of strategic planning, policy assistance, investment support and perfect supervision. For example, through the implementation of the "National Innovation and Skills Plan", Canada set up a strategic innovation fund for digital transformation, adding more than 70,000 jobs, driving more than 45 billion US dollars of investment, and injecting new vitality into the national economy; Vietnam pushes the "National Digital Transformation Plan in 2025", vigorously advocates the adoption of emerging digital technologies, builds a digital government, and sets a long-term goal that the digital economy will account for 30% of the national GDP by 2030; Egypt has vigorously promoted the "ICT 2030 Strategy" and the "Digital Egypt" plan, thus becoming the leader of digital transformation in the Middle East. Therefore, the report believes that the promotion of national digital competitiveness is closely related to the government’s clear long-term goal of digital transformation and leading the formulation and implementation of comprehensive planning for digital transformation.

To enhance digital competitiveness, we need to support digital innovation and entrepreneurship.

The research report found that countries with rapidly rising digital competitiveness pay great attention to attracting international talents, promoting innovation and entrepreneurship, and strengthening the education and training of digital skills. For example, Italy has established a legal framework to provide visa convenience and tax incentives for start-up companies and scientific and technological talents through the Entrepreneurship Law (ISA), thus attracting tens of thousands of start-up companies to register and operate in Italy in just three years; The Spanish government has launched a series of entrepreneurship support policies, including the Entrepreneurship Promotion Law, the establishment of a national entrepreneurship office, and the introduction of outstanding international talents. Georgia is actively implementing the "2017-2021 Strategy for the Unification of Education and Science" to promote the modernization of science, technology and innovation system.

In view of this, the research report emphasizes that each country needs to fully develop its own digital thinking mode and digital ecosystem, and pay attention to the speed and effectiveness of policy implementation in order to improve its digital competitiveness. At the same time, from the evaluation results of global digital competitiveness in 2021, under the influence of multiple factors, the speed of digital transformation varies greatly among different countries, and the global competition pattern around digital transformation also shows a rapid change trend, and there may be many possibilities in the future. Generally speaking, countries that attach importance to and vigorously promote digital transformation can basically make significant progress in a relatively short period of time. Even countries with weak digital foundation can realize the acceleration of digital transformation after taking appropriate actions and measures. Therefore, governments should attach great importance to and carefully consider the future strategic decision-making and management mode in this key field, and effectively promote digital transformation based on actual national conditions.

Eight ministries and commissions jointly control the illegal map of the Internet. Google says it has no basis.


  But said it would cooperate with the government to legislate.


  Eight ministries and commissions, including the State Bureau of Surveying and Mapping, the Ministry of Foreign Affairs, the Ministry of Public Security, the Ministry of Industry and Information Technology, the State Administration for Industry and Commerce, the General Administration of Press and Publication, the Information Office, and the Secrecy Bureau, joined hands to launch a special campaign nationwide for the first time. It is reported that this action began in April and will last until the end of the year. Google Maps, the difficulty of rectification named by experts, claimed that it was very wrong, and said that the current laws and regulations on Internet maps in China are blind spots, but it will cooperate with the government to do a good job in legislation.


  The problem of errors, omissions and secrets of Internet maps is prominent.


  Min Yiren, deputy director of the State Bureau of Surveying and Mapping, said in an interview that at present, the problems existing in Internet maps are mainly manifested in the following aspects: first, marking a large part of China’s territory abroad in map representation; Second, it omitted to draw important islands such as South China Sea Islands, Diaoyu Islands and chiwei yu. Third, Taiwan Province, our territory, is represented as an independent country or Taiwan Province Island is omitted; The fourth is to draw the administrative boundaries of our country by mistake and publish important geographical indication information without authorization; The fifth is to mark some sensitive, undisclosed and even related information involving state secrets on the map.


  By searching keywords on many domestic and foreign websites that provide China map search, the reporter found that these websites all have the problem of marking the location of geographic information, and marked some sensitive, not open and even related information involving China’s secrets on the map. On a website called "China Emergency Network" (emss.cn), there is a schematic diagram of more than 300 emergency centers in China on its self-made emergency map of China. However, this map has wrongly drawn China’s border line, and has drawn a large part of China’s territory abroad.


  Relevant persons from the State Bureau of Surveying and Mapping said that because the network map is in a dynamic form, it is updated quickly, and the websites copy and upload each other, so the problems existing in the network map are not only common, but also spread quickly and have a wide range of influence.


  The lack of supervision of servers is a problem.


  Why are there so many "problem maps" on the Internet? Li Yongxiong, director of the Department of Surveying and Mapping Achievements Management and Application of the State Bureau of Surveying and Mapping, believes that one of the reasons is to make and upload the server at will. "At present, only a few maps published on the official website of the Olympic Games have been audited by the administrative department of surveying and mapping. Internet maps that violate laws and regulations are widespread. " He said.


  According to him, at present, many geographic information service enterprises draw electronic maps of catering and tourism services through GPS locators without the qualification of surveying and mapping. "This kind of electronic map made by" surveying and mapping by the whole people "is not only rough, but also full of mistakes. It is also possible to mark some geographical information involving state secrets. " Li Yongxiong said.


  A spokesman for Google China said that the basic geographic data sources of Google Maps were obtained from units with official surveying and mapping qualifications. Some experts pointed out that it is a difficult point to rectify a commercial website that provides map services like Google, whose server is abroad, if there is a "problem map".


  However, the reporter saw on Google and other websites that users can indeed modify and upload map-related place names, building names and other information at will, and advertise their own business.


  Internet map market oligopoly


  Min Yiren, deputy director of the State Bureau of Surveying and Mapping, believes that errors in Internet maps not only harm the interests of consumers, but also harm the interests of the state. He said: "Internet map is also the main form of national territory, and the wrong national territory is easy to cause our diplomatic passivity." For this view, Google China does not agree-Google China insists that the legislation on Internet maps in China is still in progress, and there is no clear legal provision on what is illegal, so the special governance action itself lacks a legal basis.


  "In fact, relevant government leaders and staff often come to Google to discuss the details of how to formulate Internet map regulations. The development of the Internet is often ahead of the law. " A spokesman for Google China said. However, several other big Internet map providers are reluctant to express their views on this matter.


  There are reasons behind Google China’s high-profile refutation of the special governance actions of the State Bureau of Surveying and Mapping, the Ministry of Foreign Affairs, the Ministry of Public Security and the Ministry of Industry and Information Technology. According to a reporter’s investigation, Google China purchased geographic data from Beijing Tumeng Technology Co., Ltd. The company not only has the ICP license "Jing ICP030699" for Internet content operation, but also has the map approval number of electronic map operation service provider issued by the State Bureau of Surveying and Mapping: "GS(2007)360".


  According to the latest research of internet society of china and China Computer Users Association, Tumeng’s market share of map search technology services has reached 53% (including the total share of website traffic such as Google China, Sina Aiwen and SouFun); And its competitor-Beijing Tuweixian Technology Co., Ltd. (drawing approval number: "GS(2006)781") has a share of 41%; The two companies have almost formed an oligopoly in the Internet map market.


  The laws and regulations need to be clearly explained by the regulatory authorities.


  Some people have raised the question: Can the approval numbers issued by the State Bureau of Surveying and Mapping to two electronic map operators be lent to other websites at will? For example, is it allowed by law for Google Maps to use the approval number of Tumen?


  "This is a bit like driving a deck car on the road. It seems to be legal. If you check it carefully, you will be exposed." Yang Qun, an analyst of Warring States Policy, commented.


  In addition, the following two acts are prohibited according to the Regulations on the Administration of Map Examination and Approval promulgated in August last year: first, the acts of not submitting maps for examination as required or using maps without examination and approval without authorization; Second, the map that has been examined and approved has not been revised according to the examination opinions. Those who commit the above acts shall be ordered by the administrative department of Surveying and Mapping of the State Council or the provincial administrative department of Surveying and Mapping to make corrections within a time limit, given a warning, and may be fined between 5,000 yuan and 20,000 yuan. The above provisions apply to both traditional maps and electronic maps.


  According to Yang Qun, another important issue that needs to be clarified is: The map data provided by a company that has been approved by the government to qualify maps to a third-party company is legal and has been examined and approved. However, if a third-party company (such as Google China) makes modifications, additions and other secondary processing on this basis, does it need to be re-examined and approved by surveying and mapping departments at all levels?


  "This issue is related to the life and death of many Internet map businesses." Yang Qun said so. (Dong Yi)
