China has promised to peak its carbon emissions by 2030 and achieve the goal of carbon neutrality by 2060. The development of clean energy is also the focus of the two sessions this year.

In this year’s government work report, it is mentioned that the action plan of carbon emission peak before 2030 should be formulated to optimize the industrial structure and energy structure; Promote the clean and efficient use of coal, vigorously develop new energy sources, actively and orderly develop nuclear energy on the premise of ensuring safety, and make contributions to the global response to climate change.

Accelerate the electrification process of terminal energy consumption

China’s goal is to reduce energy consumption per unit of GDP by 3% in 2021; By the end of 2025, the use of non-fossil fuels will increase from the current 15% to 20% of the total energy consumption, including the construction of more nuclear power plants and clean energy facilities. Before the two sessions, the State Grid has announced the upgrading of the network, reducing coal-fired power generation and increasing investment in electric vehicle charging stations.

In this year’s NPC deputies’ proposals and CPPCC members’ proposals, a number of business leaders of listed companies put forward suggestions for industry development. Shu Yinbiao, member of Chinese People’s Political Consultative Conference and chairman of China Huaneng Group Co., Ltd., believes that accelerating the electrification process in the field of terminal energy consumption is an important way to help peak carbon dioxide emissions to be carbon neutral. By 2060, the proportion of electric energy consumption in China must reach more than 70%.

Shu Yinbiao proposed to further expand industrial electrification and promote energy conservation and emission reduction; Greatly improve the electrification level of building energy; Accelerate the electrification of transportation; Accelerate the breakthrough of key core technologies and provide scientific and technological support for the green transformation of energy consumption patterns.

In the field of transportation, China’s power battery technology is replacing the engine technology that German is good at, in the field of power generation, China’s smart fan is replacing the gas turbine that American is good at, and in the field of materials, China’s rising synthetic biotechnology will surpass the traditional chemical technology.

At present, electric vehicle companies including Tesla are actively promoting the construction of charging piles in China. According to the latest data released by Tesla, as of March 2021, the number of Tesla super charging piles in Chinese mainland has officially exceeded 6,000, reaching a new milestone.

In addition, Tesla Shanghai Super Charging Pile Factory was officially completed and put into operation in February 2021, with an initial planned annual production capacity of up to 10,000. Previously, Tesla super charging piles were imported from the United States.

Zeng Yuqun, member of Chinese People’s Political Consultative Conference and chairman of Contemporary Amperex Technology Co., Limited, pointed out in the proposal of the two sessions that renewable energy sources such as wind power and solar power generation are random and fluctuating, and large-scale grid connection affects the stable operation of the power grid. The "new energy+energy storage" model will provide strong support for the large-scale development and grid connection of renewable energy. At the same time, as the key of energy storage conversion, energy storage system can improve the safety, flexibility and adjustability of multi-energy system, and is the core of building energy Internet.

Zeng Yuqun suggested strengthening the top-level design to avoid inefficient allocation of resources; Accelerate the reform of the electricity market and form a long-term market-oriented mechanism of "who benefits and who pays"; Formulate and improve the energy storage standard system to ensure high-quality application of energy storage; Introduce policies to promote the construction of energy storage cloud platform and support the full utilization, sharing and internetization of electrochemical energy storage; Vigorously promote new energy power generation and build large-scale energy storage power stations to promote the balanced economic development between the east and the west.

Building a new zero-carbon industrial system

Zhang lei, deputy to the National People’s Congress and CEO of Yuanjing Technology Group, suggested speeding up the construction of a new zero-carbon industrial system. Zhang lei told China Business News: "The global industrial system will undergo earth-shaking changes in the next 20-30 years. Not only will energy production completely shift to zero-carbon renewable energy, but also industrial systems such as transportation, construction, steel and chemical industry that use energy will undergo major changes in technical routes and production equipment. "

He believes that China, as the "factory of the world", will face unprecedented challenges. China’s industrial system is based on high-intensity carbon emissions. In 2019, China’s carbon emissions reached 10 billion tons, accounting for about 30% of the global emissions. The EU is about to propose a carbon border adjustment mechanism to levy a carbon differential tax on imported products; The United States and Britain are also planning similar mechanisms. If China manufacturing does not realize zero-carbon transformation, China’s export as a "world factory" will face enormous challenges.

"China has the first-Mover advantage in the field of green technology, which is conducive to building a new zero-carbon industrial system." Zhang lei said, "China has established a leading green industry in the world, especially in photovoltaic and wind power generation, energy storage and power batteries, electric vehicles, intelligent Internet of Things and other fields. China is the world’s largest green economy and market, and it is also one of the global green technology innovation centers. Together with the green and intelligent energy infrastructure, it will lead China to establish a new zero-carbon industrial system. "

Cao Renxian, deputy to the National People’s Congress and chairman of Sunshine Power, believes that the benchmark value of carbon emissions should be strictly accounted for, the national carbon market should be expanded to cover industries and the threshold for inclusion in enterprises should be cancelled. He suggested lowering the benchmark value of carbon emissions as soon as possible, promoting technological progress in the industry by market means, and improving the enthusiasm of enterprises to reduce emissions; We will expand the coverage of industries in the national carbon market and cancel the entry threshold for enterprises. We will include key industries such as petrochemicals, chemicals, building materials, steel, non-ferrous metals, paper making and civil aviation in the national carbon market trading system, and no longer set the threshold for annual emission of 26,000 tons of carbon dioxide equivalent, so as to avoid the lack of fair obligations for carbon emissions caused by a large number of small and medium-sized enterprises.

WISCO, member of Chinese People’s Political Consultative Conference and chairman of Goldwind Technology, suggested improving the guarantee, incentive and assessment mechanism of green power consumption to ensure that green power should be fully issued and fully guaranteed; Establish a fair and open electricity market trading mechanism, as well as green electricity-related certification standards and subscription mechanisms to improve the awareness and enthusiasm of green electricity consumption in the whole society.

Iii. Emergency prevention and control measures during the epidemic period

Improve the school’s emergency prevention and control mechanism to deal with the epidemic situation, improve the emergency prevention and control plan according to the situation, and improve the emergency guarantee mechanism.

In the case of normal prevention and control, there is generally no need to take emergency prevention and control measures. When the school finds the infected cases in Covid-19, it comprehensively judges the epidemic situation and adopts scientific and precise prevention and control measures, and it is not allowed to simply adopt "one size fits all" practices such as school closure and all-staff nucleic acid testing. During the epidemic period, we should comprehensively evaluate the virus variation, epidemic intensity, medical resource load and social operation. According to the infection situation of teachers and students and the shortage of medical resources, we can take temporary emergency prevention and control measures according to law, such as suspending unnecessary large-scale gathering activities, limiting the flow of public places in schools, online teaching, etc., to reduce the gathering and flow of people in time and reduce the impact of the short-term surge of infected people on campus education and teaching order.

10. Carry out patriotic health campaign on campus. Summarize the effectiveness and experience of using the education system to prevent and control epidemics, vigorously carry forward the great anti-epidemic spirit of the new era, and cultivate and practice socialist core values. Combining with the reality of educational work, we should enrich the contents and forms of campus patriotic health campaign in the new era, improve the campus environment, improve health literacy, and promote the transformation of campus patriotic health campaign from environmental health management to teacher and student health management.

Iii. Emergency prevention and control measures during the epidemic period

In the case of normal prevention and control, there is generally no need to take emergency prevention and control measures. During the epidemic period, under the guidance of the local epidemic prevention and control mechanism (leading group and headquarters), the virus variation, epidemic intensity, medical resource load and social operation can be comprehensively evaluated, and temporary prevention and control measures can be taken in time according to the infection situation of teachers and students and the shortage of medical resources, and offline teaching can be stopped and temporary online teaching can be implemented in class or grade. After the epidemic situation is lifted, offline teaching will be resumed in time.

After the infected person appears in the school, report to the education administrative department and disease control institution at the county (district) level as soon as possible. Under the guidance of education, health and disease control departments, do a good job in the health monitoring of teachers and students, clean and disinfect the environment and the surface of objects in time, ventilate them, and do a good job in the collection and harmless treatment of garbage, feces and sewage on campus. During the period of living at home, infected teachers and students should stay in a well-ventilated and relatively independent room as far as possible, reduce close contact with people living together, and do not go out unless necessary.

Technical Scheme for Prevention and Control of Infection in Nursery Institutions in novel coronavirus (Seventh Edition)

In order to implement the Overall Plan of "Class B and B Management" for novel coronavirus Infection, the novel coronavirus Infection Prevention and Control Plan (10th Edition) and the School novel coronavirus Infection Prevention and Control Work Plan, scientifically guide nurseries to further optimize management measures, strengthen the collaborative linkage among nurseries, communities and families, ensure health, prevent severe cases and effectively restore normal care order, this technical plan is formulated in combination with the actual situation of nurseries.

First, before opening the park

(A) the preparation of child care institutions

1. Prepare for the opening of the park. Under the guidance of education administration, health and disease control departments at all levels, nurseries and kindergartens should clarify their work responsibilities and refine prevention and control measures according to the epidemic situation and the relevant policy requirements of local epidemic prevention and control. Before opening the park, they must improve the preparations for epidemic prevention and control, scientifically formulate the work plan for opening the park and the work plan for epidemic prevention and control, and strengthen the emergency response plan and corresponding guarantee mechanism.

The education department implements the responsibility of industry management, strengthens daily guidance, training, supervision and inspection, and timely coordinates and solves the difficulties and problems in epidemic prevention and control in kindergartens. The education department shall, jointly with the disease control department, guide kindergartens to do a good job in epidemic prevention and control according to their duties, and jointly with the health department to guide the training of health technicians and establish a green channel for transferring infections in the park to relevant hospitals for treatment. The person in charge of the nursery institution is the first person responsible for the epidemic prevention and control of the unit, and is fully responsible for the leadership and responsibility implementation of the epidemic prevention and control organization.

3. Strengthen departmental linkage. Nursery institutions strengthen communication and cooperation with disease control institutions, nearby designated medical institutions, maternal and child health care institutions, community health service institutions, improve the multi-sectoral collaborative working mechanism, and ensure the orderly progress of epidemic prevention and control and routine work before the opening of the park.

4. Enrich epidemic prevention materials. According to the reality of kindergartens, strengthen the construction of health care rooms, rationally plan and set up health observation rooms, which are relatively independent, and provide temporary observation for faculty and children with symptoms such as fever. Do a good job in the storage of epidemic prevention materials such as masks for children and adults, antigen detection reagents, hand sanitizers, disinfectants, non-contact thermometers, pulse oximeters, etc., manage them by special personnel, standardize their correct use, and check them regularly to ensure that the items are within the validity period and stored safely. Equipped with a sufficient number of toilet facilities and toiletries. Smooth safe and reliable emergency materials supply channels to ensure adequate supplies in emergency situations.

5. Implement environmental disinfection. Before the opening of the park, thoroughly clean and disinfect the key places, public appliances and air conditioning and ventilation systems in the park, do a good job in garbage removal, carry out preventive disinfection on the surfaces of high-frequency contact objects such as door handles and escalator handrails, and implement the ventilation system for living and nursing indoor places and public places such as activity rooms, sleeping rooms, washrooms and toilets.

6. Ensure the safety of food and drinking water. Implement the Notice on Doing a Good Job in School Food Safety in the Spring of 2023 issued by the General Administration of Market Supervision and other four departments to strengthen food safety management.

9. Actively reduce aggregation. Before the opening of the park, parents should make good preparations for child care and epidemic prevention materials. In case of epidemic situation, faculty and children’s families should reduce gathering activities and comply with prevention and control requirements when going to public places.

(three) the supervision and inspection before the opening of the park

Local education administrative departments, in conjunction with health and disease control departments, strengthen supervision and inspection on the preparation of the park and the prevention and control of epidemic situation in the park, and carefully inspect the construction of health rooms, professional personnel, medical facilities, equipment and medicines, morning and afternoon inspection system, epidemic situation reporting system of infectious diseases, follow-up registration system for absence due to illness, health monitoring, novel coronavirus infection diagnosis and treatment, mental health work, health education and publicity and training on infectious disease prevention and control knowledge, health guidance for infected teachers and students during rehabilitation, cleaning and disinfection of key areas, etc.

Second, after the opening of the park

(A) nursery management requirements

1. Wear masks scientifically according to the scene, crowd and epidemic situation. After the opening of the park, children do not wear masks during the park. Teachers and staff are not required to wear masks during their stay in the park, but can choose whether to wear masks according to their personal health and wishes. Kindergarten doctors, security guards, cleaning and canteen staff should wear medical surgical masks when they take up their posts. When faculty and children have symptoms related to Covid-19 infection, such as fever, dry cough, sore throat, etc., they should be tested for antigen or nucleic acid as soon as possible for medical investigation. If they are positive, they should be treated at home for the time being until they recover, and they should not work or enter the park with illness; If it is negative, you should wear a medical surgical mask during the park until the symptoms disappear. If a child care institution finds an infected person in Covid-19, the children in the class where the infected person is located, the faculty and children who are in close contact with the infected person should wear masks for five consecutive days and do a good job in health monitoring; Encourage children and teachers in other classes to wear masks. After leaving the park, faculty and children should wear masks scientifically according to the relevant requirements of local social epidemic prevention and control. If there is an epidemic in the local area, the prevention and control measures of wearing masks in the faculty park will be resumed.

2. Do a good job in health monitoring. Novel coronavirus infection symptoms such as fever, dry cough and sore throat were monitored in combination with the actual situation, and antigen or nucleic acid detection was carried out as needed. Strictly implement the morning and afternoon inspection system, the epidemic reporting system of infectious diseases, and the follow-up registration system for absenteeism due to illness. Children with fever and other symptoms should be tested for antigen or nucleic acid, and parents should be instructed to take it back safely immediately.

3. Strengthen site management.

Check whether the food raw materials have expired or deteriorated, and immediately clean up the food raw materials that have problems and destroy them as required. According to the characteristics of children’s growth and development, arrange meals reasonably, provide enough fresh fruits, vegetables and dairy products, and appropriate amount of fish, poultry, eggs and lean meat every day to ensure a variety of foods.

5. Strengthen health education. Strengthen the health guidance for the recovery period of infection and guide the health management during the recovery period. Strengthen publicity and guidance and policy interpretation, and carry out publicity and education on prevention knowledge of infectious diseases such as novel coronavirus infection, norovirus diarrhea, tuberculosis, influenza, measles, chickenpox, mumps, hand, foot and mouth disease and bacillary dysentery for faculty, parents and children through various forms. Teach children the correct way to wash their hands and the way to block coughing and sneezing, and cultivate children to develop good habits of washing their hands frequently, paying attention to hygiene and etiquette.

6. Pay attention to emotional changes. Pay attention to children’s diet and emotional behavior changes. Encourage the allocation of professional mental health education teachers for children, and let children know about novel coronavirus infection prevention through picture book reading, games and other activities.

7. Carry out patriotic health campaign. Combined with the reality of conservation work, vigorously carry forward the great anti-epidemic spirit of the new era, enrich the content and form of patriotic health campaign in kindergartens, improve the environment, improve the health literacy of teachers and staff, and promote the transformation of patriotic health campaign from environmental health management to health management.

(2) Management requirements for faculty, parents and children

8. Strengthen personal protection. During work, security guards, cleaning staff and canteen staff should adopt correct methods to wash their hands and strengthen hand hygiene. Dining room staff should wear disposable gloves, overalls and working caps, and keep them clean, washed and disinfected regularly. When children leave the park, parents should take good care of them. In case of epidemic, they should reduce gathering, and infants under 3 years old should try their best to go to crowded places and do personal protection.

9. Strengthen prevention and control of myopia. According to the characteristics of children’s age, arrange physical exercise with appropriate content and form, and children over 3 years old should have at least 2 hours of outdoor activities every day. Guide children to develop the habit of using their eyes scientifically and strictly control the viewing time. Balance nutritious diet, arrange work and rest reasonably, ensure adequate sleep time and improve immunity.

Iii. Emergency prevention and control measures during the epidemic period

In the case of normalization, it is generally unnecessary to take emergency prevention and control measures. During the epidemic period, the local epidemic prevention and control mechanism (leading group, headquarters) comprehensively evaluates the virus variation, epidemic intensity, medical resource load and social operation, and can take temporary emergency prevention and control measures such as suspending the opening of the park according to the infection of faculty and children and the tension of medical resources. After the epidemic situation is lifted, the conservation order will be restored in time.

Infected faculty and children should stay in well-ventilated and relatively independent rooms as much as possible during their stay at home, so as to reduce close contact with the people who live with them and not go out unless necessary.

　　On April 21st, the opening ceremony of the 2022 annual meeting of Boao Forum for Asia was held in Boao, Hainan. The top leader of president delivered a keynote speech entitled "Meeting Challenges Together and Creating the Future through Cooperation" by video.

　　President Xi’s keynote speech, based on Asia and looking around the world, comprehensively analyzed the common challenges facing the world at present, accurately grasped the general trend of development since the outbreak of the COVID-19 epidemic, once again declared China’s firm stance of opening up to the outside world at a high level and seeking common development with other countries, and sincerely appealed to the international community to strengthen confidence and advance hand in hand. Under the current complicated and severe international situation, President Xi’s important speech is of great significance to promoting peaceful development, win-win cooperation among all countries, and also to build a broad consensus and powerful force for mankind to create a better future.

　　At present, the change of the world, the change of the times and the change of history are unfolding in an unprecedented way, which poses a series of challenges to mankind that must be taken seriously. How to overcome the epidemic and build a post-epidemic world, how to promote the stable recovery of the world economy and achieve sustainable development, how to reduce the tension and opposition in international relations and seek win-win cooperation. Faced with this series of important and serious practical issues, all countries should conform to the trend of the times, grasp the correct direction, and persist in helping each other in the same boat in order to get out of the fog and move towards the light.

　　"We must jointly protect human life and health, we must jointly promote economic recovery, we must jointly safeguard world peace and tranquility, and we must jointly meet the challenges of global governance." From strengthening the coordination of epidemic prevention measures and improving global public health governance, to strengthening macro-policy coordination and maintaining the stability of global industrial chain supply chain, from building a balanced, effective and sustainable security framework to practicing the concept of global governance, the Chairman of the Supreme Leader profoundly explained China’s solutions to a series of current global challenges with "four commons", which contributed China wisdom to realizing a more inclusive and fair global development vision.

　　Asia is better than the world. In recent years, Asian countries have overcome many obstacles such as the impact of the epidemic and the disorder of multilateral rules, firmly promoted regional economic integration, and sought to achieve all-round and wide-ranging cooperation and win-win, which provided new ideas for globalization and important support for multilateralism. Asian countries should continue to demonstrate Asia’s resilience, wisdom and strength, firmly safeguard Asian peace, actively promote Asian cooperation, jointly promote Asian unity, and build an anchor for world peace and stability, a source of growth and a new highland for cooperation.

　　"The fundamentals of China’s strong economic resilience, sufficient potential, wide room for manoeuvre and long-term improvement will not change, which will provide strong kinetic energy for the stabilization and recovery of the world economy and provide broader market opportunities for countries." Over the years, Boao Forum has witnessed and will continue to witness the infinite opportunities that China has brought to the common development of the world through deepening reform and opening wider to the outside world. At this forum, President Xi also announced that China will fully implement the Regional Comprehensive Economic Partnership Agreement, actively promote its accession to the Comprehensive and Progressive Trans-Pacific Partnership Agreement and the Digital Economy Partnership Agreement, and so on, and issued a sincere invitation to all countries to join hands, fully demonstrating China’s mutually beneficial and win-win opening strategy, and showing that China has always made unremitting efforts and due contributions to building a global community of development and destiny through pragmatic actions.

　　In his keynote speech, the Chairman of the Supreme Leader stressed: "All countries in the world are on a big ship with a common destiny. If they want to cross the stormy waves and sail for a bright future, they must help each other in the same boat. It is unacceptable to try to throw anyone into the sea." Under the background of the interweaving of the changes in the past 100 years and the epidemic in the century, all countries in the world should take a series of challenges seriously together, strive to transcend the differences in ideology and social system, gather the great strength of win-win cooperation, and work together with one heart and one mind to overcome all kinds of challenges and usher in a brighter and better future for mankind.

Implementing the new development concept is the only way for China’s development and growth in the new era, in which coordinated development plays an important role in China’s overall development. We must adhere to overall planning and comprehensive balance, and actively promote all-round development in various regions and fields. The coefficient of variation can be used to measure the level gap and its changing trend of economic and social development in different regions and fields in China, and provide statistical basis for formulating regional coordinated development strategies. The coefficient of variation plays an important role in analyzing the differences and heterogeneity of observed values.

I. What is the coefficient of variation?

Coefficient of variation is a relative statistic to measure the degree of variation of data, which is used to compare the degree of variation of two or more sample data with different average values, and is the ratio of standard deviation to its average value. It can also be called dispersion coefficient and standard deviation coefficient.

Second, what is the function of coefficient of variation?

The coefficient of variation is mainly used to compare the dispersion degree of different groups of data. When comparing the variation degree of two or more sample data, if the unit of measurement is the same as the average, the standard deviation can be directly used for comparison; If the measurement units or averages are different, the standard deviation cannot be used to compare the degree of variation, but the coefficient of variation (relative value) should be used for comparison. The coefficient of variation is a dimensionless quantity, which can eliminate the influence of data value or measurement unit on the comparison of dispersion degree of two or more sample data. The smaller the coefficient of variation, the smaller the degree of variation of sample data; Conversely, the greater the coefficient of variation, the greater the degree of variation of the sample data. When observing the variation trend of coefficient of variation, we should also analyze it together with the average value and standard deviation.

Third, how to calculate the coefficient of variation

The coefficient of variation is the ratio of the standard deviation of a set of sample data to its mean value, and the calculation formula is:

Among them,Is the coefficient of variation,Is the standard deviation,Is the mathematical expectation or average. Usually, the coefficient of variation is meaningful only when the average value is not zero, and it is generally applicable to the case where the average value is greater than zero; When the average value is close to zero, the value of the coefficient of variation tends to infinity, which must be carefully explained at this time.

Fourth, data interpretation

Taking the per capita GDP of different regions in China as an example, this paper analyzes the changes of regional economic development level differences in China. Table 1 shows the coefficient of variation of per capita GDP of 31 provinces in China from 2013 to 2022.

Table 1 Coefficient of variation of GDP per capita in 31 provinces (2013-2022)

Figure 1 Coefficient of variation of GDP per capita in 31 provinces (2013-2022)

Since the 18th National Congress of the Communist Party of China, the CPC Central Committee has put forward new development concepts, promoted high-quality development, and formulated a series of major strategies with overall significance, and China’s economic strength has achieved a historic leap. As shown in Figure 1, from 2013 to 2022, the average level of per capita GDP of 31 provinces in China has been rising, and the coefficient of variation and range ratio (measured by the ratio of maximum to minimum) have shown a trend of first expanding and then decreasing, indicating that the differences in development levels among regions fluctuated during the painful period of economic development, but the overall decreasing trend remained unchanged. The ratio of maximum value to minimum value decreased from 4.55 times in 2013 to 4.23 times in 2022, and the coefficient of variation decreased from 44.82% in 2013 to 42.73% in 2022. Generally speaking, in the past 10 years, the regional economic development gap in China has narrowed, and the overall regional economic development has become more coordinated.
