Recently, the "China Construction Development Forum, High-level Seminar on Carbon Neutralization and High-quality Development of Construction Industry" co-sponsored by china construction news Society and Gansu Provincial Department of Housing and Urban-Rural Development was held in Lanzhou, Gansu Province, to implement the national policy, explore the development path of "peak carbon dioxide emissions" and "carbon neutrality", discuss the strategy of green transformation and high-quality development of construction industry, and help achieve the goal of "double carbon".

Wang Guangzhao, the second-level inspector and chief engineer of the Gansu Provincial Department of Housing and Urban-Rural Development, said in his speech that the goal of "double carbon" is closely related to the overall development level of the construction industry. The construction industry is a traditional industry with obvious labor-intensive characteristics, low degree of industrialization, the application level of informatization and digitalization needs to be improved, and the extensive construction method needs to be changed. In August last year, the Ministry of Housing and Urban-Rural Development and other nine departments jointly issued "Several Opinions on Accelerating the Industrialization Development of New Buildings", proposing that the project construction should be driven by a new generation of information technology to achieve high efficiency, high quality, low consumption and low emissions; At the beginning of this year, the Ministry of Housing and Urban-Rural Development pointed out that one of the key tasks this year is to "accelerate the development of green buildings, vigorously promote building energy conservation, and make contributions to achieving the goals of peak carbon dioxide emissions and carbon neutrality". This plans the implementation path of the "double carbon" goal from the top-level design, and makes it clear that developing new building industrialization will be an important measure for green development and low-carbon circular development in the field of urban and rural construction in China.

He believes that in order to realize transformation and upgrading, improve quality and increase efficiency, the construction industry must change from "path dependence" to "path innovation", from "traditional mode" to "high quality development" and from "construction worker" to "construction craftsman". He emphasized that the construction industry should seize the huge development opportunity brought by the green transformation, promote the deep integration of building industrialization, informationization and intelligence, vigorously develop prefabricated buildings, green buildings and ultra-low-energy buildings, and improve the production efficiency of the industry through informationization and digitalization, and promote the low-carbon development of the construction field with dual control of energy consumption and carbon emissions.

According to Tiehong Wang, former chief engineer of the Ministry of Housing and Urban-Rural Development and president of the 6th Council of China Construction Industry Association, one of the key points of the green transformation and upgrading of the construction industry is to "vigorously promote prefabricated buildings". Tiehong Wang said that the future has come, and the double superposition of transformation and upgrading and technological leapfrogging has come simultaneously, which is highlighted in the "three perfect matches": First, assembly +BIM (building information model). Qingdao International Conference Center project adopts all-steel structure and full assembly, and the structure-electromechanical-decoration full assembly will be completed in just six months, which is good, economical and fast. They sincerely feel that it can’t be achieved without BIM. When to place an order, when to go to the production line, when to pack and transport, when to arrive at the site, who will install it, who will accept it, etc., all depend on BIM big data. The second is assembly +EPC (general contracting). To truly promote the development of assembly, it is difficult to achieve better, more economical and faster without EPC, so we must highlight EPC. In this respect, China Construction Technology Group Co., Ltd. has accumulated a good experience of assembly +EPC. The third is assembly+ultra-low energy consumption. In the future, passive buildings with ultra-low energy consumption will have broad development space in China. Especially in Leng Xia hot area in winter, it is very suitable for popularizing passive buildings with ultra-low energy consumption. Ultra-low-energy passive building is based on energy-saving building and green building, which makes the effect of heat preservation, heat insulation and fresh air better.

On this basis, the next step, assembled +AI smart construction will be a new and broad field. Every year, more than 270,000 new construction projects and industrial scenes with a total output value of more than 26 trillion yuan are fully intelligent (including factory intelligence and on-site intelligence). What a huge blue ocean, it will greatly enhance the scientific and technological level of the construction industry. As the Supreme Leader General Secretary has painted, "Made in China, created in China and built in China work together to continue to change the face of China".

Su Yuehua, Party Secretary and Chairman of Gansu Construction Investment (Holding) Group Co., Ltd. (hereinafter referred to as "Gansu Jiantou"), shared the practice of Gansu Jiantou in promoting the green transformation and upgrading of enterprises in recent years. He said that in recent years, Gansu Jiantou jumped out of the single building construction in the past, transforming from an engineering contractor to an investor and operator, from a "construction engineering group" to a "construction investment group" and then to an "investment group". Gansu Jiantou has shown its potential as a "singles champion" in the regional market by giving full play to its industrial cultivation function, cultivating emerging industries, optimizing the industrial structure, promoting the transformation and upgrading of traditional construction industries, and cultivating and expanding emerging industries such as eco-environmental, green building materials, wind power and photovoltaic, prefabricated buildings and new energy, and has formed an industrial layout that combines light and heavy assets in sub-sectors and gives consideration to the present and the future. In particular, efforts have been made to develop green prefabricated buildings, and three prefabricated building industrial parks have been invested and built in Lanzhou New District, Yuzhong and Tianshui, forming a whole industrial chain of prefabricated buildings integrating investment and financing, scientific research, design, reinforced concrete components, steel structure processing, new wallboard development, construction and installation.

At present, Gansu Jiantou is studying and formulating an implementation plan to implement the "double carbon" strategy and making positive contributions to helping achieve the national "double carbon" goal. At the same time, we are seizing the opportunity of policy superposition, grasping the green and low-carbon development trend of the industry, increasing investment and construction in the fields of traditional construction industry transformation and upgrading, green construction, ecological environment protection, new energy wind power, static transportation, etc., promoting the integration of green development concept into the whole factor, whole process and whole life cycle of engineering construction, and effectively promoting the high-quality development of enterprises.

Han Aisheng, president of Hangzhou Xinzhongda Science and Technology Co., Ltd. said that during the "14th Five-Year Plan" period, the development of the construction industry faced a new situation, which was embodied in the fact that the "double carbon" goal outlined a new path of low-carbon development, the industrialization of construction entered a new stage of development, the fiscal and taxation reform entered a "deep water zone", the industry supervision was continuously strengthened, and the new infrastructure brought huge opportunities for upgrading the track. At the same time, new technologies such as cloud computing, big data, Internet of Things, mobile Internet and artificial intelligence are deeply integrated with the transformation and upgrading of traditional industries. The superposition of new situation and new technology trends determines the new pattern of construction industry transformation.

The transformation of the construction industry will certainly promote the upgrading of enterprise management and project management, and "digitalization" will become the most powerful support for construction enterprises to build new capabilities such as efficient decision-making ability, cost management ability, contract management and control ability, fund risk control ability, industrial tax and financial integration ability, digital construction ability, industrial synergy ability, and technical middle-platform ability. At the same time, enterprise standardization, informatization, refined management upgrading, project management, fiscal and taxation management and digital site management upgrading will become the "hard demand" for the transformation and upgrading of construction enterprises. In this situation, the demand for professional digital technology and products and services that can solve the management pain points and transformation difficulties will gradually increase.

"China Construction Development Forum, High-level Seminar on Carbon Neutralization and High-quality Development of Construction Industry" is a series of meetings, which have been held successively in Beijing and Lanzhou, Gansu. In the later period, the conference will go to other regions, so that more colleagues in the construction industry can make clear the goals of peak carbon dioxide emissions and carbon neutrality through exchanges, recognize the transformation path, and help the high-quality development of industry enterprises.

Science and technology are the foundation of national prosperity, and innovation is the soul of national progress. The Fifth Plenary Session of the 19th CPC Central Committee put forward that "innovation should be the core of China’s overall modernization drive, self-reliance and self-reliance in science and technology should be the strategic support for national development, and the strategy of rejuvenating the country through science and education, strengthening the country through talents, and innovation-driven development should be implemented in depth, so as to improve the national innovation system and accelerate the construction of a strong country through science and technology", and to strengthen the national strategic scientific and technological strength, enhance the technological innovation capability of enterprises and stimulate talent innovation. This is a major strategic decision made by the CPC Central Committee with the Supreme Leader as the core at a new historical height and starting from the overall strategic situation, which is of great and far-reaching significance.

In this context, further deepening the integration of production and education, and promoting the organic connection between education chain, talent chain and industrial chain, and innovation chain are the inevitable requirements and pragmatic measures to improve the national and regional innovation system and promote the self-reliance of science and technology.

The integration of production and education is an innovative form, which can break through the barrier between education and industry, connect the first productive force of science and technology, the first resource of talents and the first driving force of innovation, effectively gather innovative elements of all parties, effectively enhance the ability and effectiveness of scientific and technological innovation, help science and technology to stand on its own feet, and further highlight the core position and leading role of innovation.

Realistically, China has a complete industrial system, strong industrial supporting capacity, and the largest higher education system in the world, but industry and education are still in their own way. There is a lack of benign interaction between industry and education, and the pattern of integrated development has not yet formed. There are "two skins" on the supply side of talent training and the demand side of high-quality industrial development to varying degrees. These problems restrict the ability and level of self-reliance and self-improvement of science and technology, and it is urgent to further deepen the integration of production and education, optimize the allocation of resources, stimulate the kinetic energy of innovation, and provide the source of innovation for realizing self-reliance and self-improvement of science and technology.

To deepen the integration of production and education and improve the quality of innovation

To achieve self-reliance in science and technology, we should not only emphasize the ability of independent innovation, but also emphasize the improvement of innovation quality. It is necessary to put scientific and technological innovation in a more prominent position, take the actual major demand as the traction, deepen the integration of production and education as the starting point, take the reform of system and mechanism as the core, strengthen the integration, integration and fusion of various innovation elements, and strive to achieve more major breakthroughs from 0 to 1.

On the one hand, it is necessary to enhance the innovation ability of colleges and universities. Colleges and universities should seize the opportunity of accelerating the construction of world-class universities and first-class disciplines, promote the cross-integration of basic disciplines and applied disciplines as a whole, support the construction of disciplines that meet the needs of the development of regional traditional advantageous industries, advanced manufacturing industries and strategic emerging industries, strengthen the guidance of the development of innovation ability of colleges and universities, promote the close connection between the innovation supply side of colleges and universities and the demand side of industrial development, build an institutional mechanism for the diversified collaborative innovation of colleges and universities with industries, industries and enterprises, and continuously improve the ability of original innovation, basic innovation, integrated innovation and collaborative innovation.

On the other hand, we should give full play to the role of innovation subject of enterprises. It is necessary to guide enterprises to make full use of the preferential policies related to the integration of production and education through the market mechanism, actively participate in scientific research and technology research and development in colleges and universities, provide the source and element support for scientific research and innovation in colleges and universities, and strive to turn scientific research resources in colleges and universities into fertile land for technological innovation in enterprises. In particular, high-tech enterprises should serve the country and take a long-term view, and joint universities should speed up the breakthrough of key core technology bottlenecks and strive to solve the technical problem of "sticking their necks".

At the same time, we should promote Industry-University-Research’s deep integration. Deploy innovation chain around the industrial chain, guide universities, industries, enterprises and scientific research institutions to form an alliance of integration of production and education, build a science park with integration of production and education, create a space for innovation, and build a pilot base, build a service platform to promote the docking of supply and demand information of production and education, promote the deep integration and integrated development of Industry-University-Research, promote the timely transformation and industrialization of scientific and technological achievements, form a complete chain of basic research, application development, achievement transfer and industrialization, and provide assistance for promoting the upgrading of industrial base and the modernization of industrial chain.

Deepening the integration of production and education and accelerating collaborative education

Talent is the most active and positive factor in innovation activities, and it is inseparable from talent support to achieve self-reliance and self-improvement in science and technology. It is necessary to accurately grasp the new requirements for the cultivation of innovative talents when higher education enters the popularization stage, and integrate the concept of integration of production and education into the whole process of talent cultivation.

First, we must strengthen the strength of the scientific and technological team. Colleges and universities have more than 60% high-level talents and more than 40% academicians of the Chinese Academy of Sciences and the Chinese Academy of Engineering. They should make good use of this precious resource, vigorously carry forward the spirit of scientists, focus on important disciplines, innovative directions, and major industrial development needs, implement the system of "revealing the list and taking the lead" in major scientific research projects, increase the introduction and cultivation of strategic scientific and technological talents, leading scientific and technological talents and innovative teams, build a new highland where innovative talents at home and abroad can gather, and provide talent guarantee for scientific and technological self-reliance.

The second is to strengthen the cultivation of innovative talents. Guided by the needs of economic and social development, we should grasp the new requirements of the new development pattern for personnel training, deepen the structural reform of the supply side of human resources, improve the dynamic adjustment mechanism of professional and industrial development in colleges and universities, build a professional system that closely connects with the industrial chain and innovation chain, improve the top-notch personnel training system of basic disciplines, and optimize the level and type structure of personnel training.

The third is to build a long-term mechanism for school-enterprise cooperation. The key is to fully mobilize the enthusiasm and initiative of enterprises to participate in the integration of production and education, strengthen policy guidance, encourage the first attempt, improve the integration of production and education, the collaborative education mechanism between schools and enterprises, deepen the reform of education and teaching and the innovation of training mechanism, and promote the docking of supply and demand and process reengineering by means of professional co-operation, textbook co-editing, teacher co-education, platform co-construction and resource sharing, so as to jointly cultivate high-quality workers and innovative talents.

Strengthen system governance by deepening the integration of production and education

The integration of production and education is a process of multi-subject resource allocation and reconstruction. It is necessary to innovate the integration mechanism of production and education with systematic concept, deepen the reform of science and technology system, and form an innovative community of mutual benefit.

In terms of organizational promotion, we will make overall plans to promote the pilot projects of cities, industries and enterprises with integration of production and education, strengthen the role of cities in carrying capacity, industry aggregation and enterprises in classification, and build distinctive pilot projects and regional innovation systems for integration of production and education. All localities need to strengthen the organization and leadership of the integration of production and education, adjust and optimize the layout of higher education according to the needs of economic and social development, accelerate the development of new research universities, improve the science and technology planning system, major project management model and sustained and stable investment mechanism, clarify the functional orientation of innovative subjects such as universities, enterprises and scientific research institutions in the regional innovation system, and make overall arrangements for basic research and key core technology research.

In terms of integration and sharing, it is necessary to improve the modern school management system and modern enterprise system, follow the market mechanism and the law of value, innovate the organizational form and operation mechanism, promote the deep integration of resources, personnel, technology, management and culture, realize the docking of "needs" and "capabilities", form an ecological system of two-way interaction and integrated transformation between "production" and "education", and expand the breadth and depth of the integration of production and education.

In terms of incentive evaluation, all localities should continue to deepen the "streamline administration, delegate power, strengthen regulation and improve services" reform, create a first-class business environment and innovative ecology, and comprehensively use fiscal, taxation, investment, finance, land, price and other incentive policies to benefit enterprises, universities and other participants in the integration of production and education; Education authorities need to improve the performance evaluation system of colleges and universities and guide them to actively participate in the integration of production and education; Colleges and universities should reform and improve the teacher classification assessment system, take scientific and technological innovation and achievement transformation as an important basis for talent evaluation, job title evaluation, achievement award and income distribution, and fully stimulate and release the innovative potential of scientific and technological talents.

　　Xinhua News Agency, Beijing, January 28th Question: what are the highlights of the "national account book" in the first year of the 14 th Five-Year Plan? — — Interview with Bai Jingming, former vice president of China Academy of Fiscal Science.

　　Xinhua News Agency reporter Shen Cheng

　　State finance is taken from the people and used by the people. In 2021, how to accurately and effectively implement a proactive fiscal policy? What are the new arrangements for the "national account book" to benefit enterprises and benefit the people? What challenges will financial operation face? Focusing on hot issues, the reporter interviewed Bai Jingming, former vice president of China Academy of Fiscal Science.

　　How can a proactive fiscal policy be accurate and effective, improve quality and increase efficiency?

　　"Accurate and effective", "Improving quality, increasing efficiency and being more sustainable" — — The Central Economic Work Conference put forward requirements for implementing a proactive fiscal policy this year.

　　In Bai Jingming’s view, the "accurate and effective" proactive fiscal policy should be reflected in three aspects: first, when fiscal policy is effective, it should control the cost at a low level; Second, fiscal policy should focus on solving the blocking points, pain points and difficulties of economic and social development; Third, the starting point of fiscal policy should be in places with strong spillover and high social benefits.

　　How to understand the fiscal policy of "improving quality and increasing efficiency" How to achieve it?

　　"Improving quality and increasing efficiency means spending as little as possible, doing good things according to quality and doing more things with a certain amount of funds." Bai Jingming said.

　　In his view, to improve quality and efficiency, on the one hand, we should optimize the structure of fiscal expenditure and use the funds in places that need to be solved urgently; On the other hand, it is necessary to strengthen management and ensure that funds are "value for money".

　　In order to cope with the impact of the epidemic and promote economic recovery, many countries have introduced their own fiscal stimulus policies. How strong is China’s fiscal policy?

　　Bai Jingming said that in 2020, China introduced a number of fiscal policies, such as increasing the deficit ratio, expanding the scale of special debts, issuing special anti-epidemic bonds, and establishing a direct financial mechanism. Compared with other countries, China’s fiscal policy is strong and time-effective, giving overall consideration to economic development and social development, and providing assistance for China’s economic recovery.

　　What are the new arrangements for the "national account book" to benefit enterprises and benefit the people?

　　As an important focus of proactive fiscal policy, in 2020, China increased tax reduction and fee reduction to help market players bail out development.

　　"In 2020, the scale of tax reduction and fee reduction in China is expected to reach 2.5 trillion yuan, accounting for about 2.5% of GDP, which shows that the government is ‘ Cut the cake ’ At that time, the funds were given to enterprises and the people, which was very strong. " Bai Jingming said.

　　In his view, it is an inevitable trend to continue to reduce taxes and fees in 2021. The situation at home and abroad is still complicated this year, and the foundation of China’s economic recovery is still not solid. Through reducing taxes and fees, we will continue to "release water to raise fish" and further stabilize the basic economic disk.

　　"The focus of tax reduction and fee reduction this year is to stimulate the vitality of market players, especially small and medium-sized enterprises, to help them overcome the impact of the epidemic and increase their development momentum."

　　In 2020, China innovatively established a direct financial mechanism. The national financial work conference held a few days ago has made it clear that this year we will continue to adhere to this effective practice and form a normalized and institutionalized arrangement.

　　"It is necessary and conditional for the direct funding mechanism to expand its scope." Bai Jingming said, after the fund of "sticking one pole in the end" is expanded in scope and scale, it can better help solve the difficulties in economic and social development and improve efficiency.

　　What are the challenges faced by financial operation?

　　According to data released by the Ministry of Finance on the 28th, the national fiscal revenue decreased by 3.9% year-on-year in 2020. Is the financial operation facing challenges?

　　In Bai Jingming’s view, last year, China’s fiscal revenue decreased year-on-year. On the one hand, it was affected by the epidemic and the economic operation was affected, which brought about a decline in fiscal revenue; On the other hand, there are also factors of self-reduction. Due to the implementation of a large-scale tax reduction and fee reduction policy, some income has been "voluntarily given up".

　　"China’s financial operation is stable from a global perspective, and basic expenditures can be guaranteed." Bai Jingming said that after taking a number of effective measures, the financial resources of basic people’s livelihood, wages and operation in grass-roots cities and counties are guaranteed. Looking forward to 2021, as the economy continues to recover, the growth rate of fiscal revenue is expected to turn positive.

　　He said that the pressure of fiscal revenue and expenditure has always existed because the demand for expenditure is infinite, but the fiscal revenue is limited. "There is a contradiction between China’s fiscal revenue and expenditure, but it is relatively speaking. This contradiction comes from the people’s demand for a better life and the growing demand for public services, which require more funds to support the promotion. "

　　Bai Jingming believes that in the long run, coping with the aging population will become a challenge for the future financial operation. China’s fiscal expenditure structure should be actively adjusted in the future, and it will be more inclined to social security, especially the pension insurance expenditure. "Where is the money used? It is applied to solving short-board problems and alleviating contradictions in economic and social development. "

　　What are the new highlights in the financial field of the 14 th Five-Year Plan?

　　During the 14th Five-Year Plan period, China entered a new stage of development, which is the stage of building a socialist modern country in an all-round way and marching towards the goal of the second century. What new attractions will there be in the financial field?

　　In Bai Jingming’s view, during the five years of the 14th Five-Year Plan, many important financial reforms can be promoted. Focusing on further improving the modern financial system, we should further deepen the reform of the financial system and improve the income distribution among governments; Further deepen the reform of budget management and strengthen budget performance management.

　　At the same time, we will further improve the fiscal expenditure policies and systems, adjust the fiscal expenditure structure, and continue to make efforts in ensuring the equalization of public services and other key expenditures.

　　"In addition, the tax reform will continue to advance." Bai Jingming said that it is necessary to further improve preferential tax policies, strengthen the coordination between tax reform and tax policies, and accelerate the construction of a new development pattern around promoting enterprise development and high-quality economic development.

"The operation is more complicated?" "Does it take a long time to get the ticket?" "Can other cities buy Chongqing but not Chongqing?" Recently, netizens reflected some questions they encountered in participating in the "National Subsidy Activities for Green Smart Home Appliances" (hereinafter referred to as "National Subsidy" activities) through the online political platform of Hualong.com.. On October 23, in response to the concerns of netizens, the political platform interviewed Hu Yangji, secretary general of Chongqing Household Appliance Service Enterprise Association, and household appliance service enterprises such as Chongqing Baibai and Midea.

Hu Yangji, Secretary General of Chongqing Household Electrical Appliances Service Enterprise Federation, was interviewed.

Hu Yangji, Secretary General of the Municipal Household Electrical Appliances Federation: It takes only 3 minutes to register China Unionpay Quick Pass in advance.

Q1: Is the operation complicated?

In response to the user’s query that the operation is complicated, Hu Yangji explained that many consumers only download China Unionpay Quick Pass and register when they make a temporary purchase, because the registration requires bank cards and identity authentication, which may make consumers feel a little troublesome.

He suggested that consumers should download and register the China Unionpay Quick Pass APP in advance before participating in the "National Supplement" activity, and complete the identity verification and bank card binding in advance. It should be noted that some bank cards have a limit, so consumers are advised to bind one type of bank card, so as to avoid the problem that the amount of bank cards is not enough to affect the experience when purchasing large-sum household appliances.

Hu Yangji said that if consumers download and register in China Unionpay Quick Pass in advance, it only takes about 3 minutes to participate in the "national subsidy" activity online, and if they receive the subsidy voucher in advance, the time will be faster.

Q2: Does it take a long time to get the ticket?

Some netizens mentioned the question of "long waiting time for obtaining coupons". Hu Yangji analyzed that after consumers submit their online signatures, they will upload them to the Ministry of Commerce for qualification examination. During this period, they may wait, but the time will not be too long. The reporter found in the experience of China Unionpay Quick Pass platform that after receiving the computer subsidy voucher for the first time and signing it, the system indicated that there were a large number of participants at present and they needed to wait. After waiting for a few minutes, the reporter resubmitted, immediately passed the qualification examination and successfully received the coupon.

Subsequently, the reporter experienced the subsidy vouchers for refrigerators and air conditioners, all of which were successful once, and there was no waiting.

Q3: Can other cities buy Chongqing but not Chongqing?

"Other cities can buy Chongqing but can’t buy it. It’s actually a category problem!" Hu Yangji introduced that at present, there are 11 categories of household appliances in Chongqing to participate in the "national subsidy" activities. If the household appliances that consumers want to buy are not in these 11 categories, then they cannot participate in the "national subsidy" activities.

He also revealed that in order to better implement this policy of benefiting the country, the people and enterprises, at present, the Chongqing Household Electrical Appliances Service Enterprise Federation has put forward a proposal to the higher authorities to expand the category, which is under discussion by the higher authorities.

Consumers of Chongbai Electric Jie Fangbei Shopping Mall are queuing for settlement.

Hu Yangji reminded consumers who participated in the "national subsidy" activities that when receiving goods, they need to cooperate with the distribution enterprises to prepare the materials for receiving goods, including: they need to provide ID cards or mobile phone numbers of UnionPay when receiving goods; The purchased goods are self-delivered, self-picked or computer products, and photos in the same frame should be provided.

Merchant: I can’t use it. It doesn’t matter. The salesperson will guide the operation.

The reporter from the political platform also came to Jie Fangbei business circle and interviewed some home appliance sales enterprises that participated in the "national subsidy" activities.

Peng Da, a salesman of Jie Fangbei Shopping Mall of Chongqing Electric Appliances Co., Ltd., said that they will actively introduce the "state subsidy" policy to consumers, actively guide consumers to buy green smart home appliances that participate in the "state subsidy" activities, implement the national policy of benefiting the people well, and at the same time make consumers get benefits. If they meet elderly customers who are unfamiliar with the operation process, they will take the initiative to serve and guide consumers to operate.

The staff of Chongbai Electric Jie Fangbei Shopping Mall is guiding consumers to participate in the "National Supplement" activity.

Libing, salesman of Midea Air Conditioning Counter in the shopping mall, said that in their counters, each air conditioner that meets the "national subsidy" policy has posted a unique logo, which also indicates "first-class energy consumption" and "second-class energy consumption" and the corresponding subsidy amount, so as to facilitate consumers’ choice.

On-site: The activity was very good, which made us benefit.

In Jie Fangbei shopping mall of Chongbai Electric, Aunt Huang bought a green smart water heater with an original price of more than 2,600 yuan for only 2,100 yuan. Aunt Huang said that she operated it herself and took out her mobile phone to demonstrate the operation process. She said: "The operation of mobile phones is very convenient. This policy is very good and benefits the people!"

The citizens are introducing their participation in the "state subsidy" activities.

Unlike Aunt Huang, Aunt Zhuang is not familiar with the use of smart phones. After she came to the shopping mall, under the guidance of the salesman, she completed the operation procedures of collecting subsidy vouchers, selecting goods, confirming and settling accounts for the "national subsidy" activity, successfully participated in the activity and bought a range hood. She said with surprise: "The original price was 1999 yuan, and I only spent more than 1600 yuan. The activity was very good and we got benefits!"

Aunt Zhuang is buying a range hood.

Editor’s Note: A scientific and reasonable urban road network structure is an important foundation for ensuring road traffic safety, maintaining road traffic order and improving road traffic capacity. In order to solve the problem of lack of in-depth research on the basic theory of road network structure in China, with the support of the basic research project "Research on Urban Road Network Portrait and Traffic Control Technology Based on Big Data" (No.11104100000180001210102), the Road Traffic Safety Research Center of the Ministry of Public Security pioneered the holographic portrait model of urban road network structure. This paper makes a concrete, subtle and intuitive quantitative analysis of road network from the aspects of road network connectivity, road grade matching, intersection shape and lane grade, and puts forward a number of quantitative indicators such as road network connectivity, 100-kilometer broken road, intersection shape, intersection spacing, intersection level difference, access level difference, high/expressway entrance and exit spacing, road linear curvature gradient and so on, and makes an all-round analytical portrait of urban road network. This research is the first at home and abroad after novelty retrieval by authoritative organizations. Since the beginning of this issue, this journal will publish articles one after another to introduce the holographic portrait model of urban road network structure in detail. In this issue, firstly, the connectivity index of urban road network in the model is interpreted.

I. Connectivity index of urban road network

Connectivity in English is a topological property of space or set. Urban road network connectivity refers to the density of intersections in urban road network and the direct degree of road connection. At present, it is generally believed that road network connectivity refers to the index that represents the interconnection between roads on the basis of a certain road network density. This index can reflect whether there are many broken roads and T-junctions.

A highly connected road network has many advantages for urban traffic and people’s travel. A highly connected environment can provide more direct roads to shorten the distance to the destination. A highly connected road network can reduce the traffic volume of main roads, make room for emergency vehicles, reduce the cost of public facilities connection and services, improve the average speed of the road network, reduce traffic congestion and reduce the probability of traffic conflicts, thus avoiding traffic accidents.

There are many methods to calculate the connectivity of road network, and these metrics are different because of different measurement methods. After synthesizing many calculation methods at home and abroad, this study adopts the connectivity index of road network generally recognized in China to reflect the connectivity level of urban road network.

Second, the calculation method of urban road network connectivity

Urban road network connectivity represents the quantitative degree of road network connectivity. The higher the value, the better the connectivity. If the density of road network is constant, the higher the connectivity of road network, the more reasonable the structure of road network is. There are two calculation methods for urban road network connectivity, as shown in Formula 1 and Formula 2.

Where: j is the connectivity of road network; N is the total number of nodes in the road network; Mi is the number of edges adjacent to the ith node; M is the total number of edges (number of road sections) of the network.

The types of urban road networks in China are mostly grid-shaped, and the connectivity of grid-shaped road networks increases with the increase of nodes, and gradually approaches 4. At the same time, under the same number of nodes, the connectivity of intersection is better than that of T-junction, and the fewer broken roads, the higher the connectivity.

Third, the actual measurement results of connectivity of 36 major cities in China

Based on the above connectivity calculation model, this study measured the actual road network of 36 major cities in China. Firstly, the built-up area and regional scope of the city are determined by remote sensing images. Secondly, the overall connectivity index of each city is calculated by navigating the actual road network vector information of the electronic map, and the following conclusions are drawn.

(A) China’s 36 major cities’ road network connectivity index is generally low.

The theory and application of urban traffic planning puts forward that the road network connectivity index of small and medium-sized cities should be between 3.2 and 3.5, and that of big cities in China should be between 3.6 and 3.9. However, according to the measured data, the connectivity of road networks in 36 key cities in China is between 3.2 and 3.4. Compared with the reasonable connectivity value of 3.6 to 3.9, the connectivity of road networks is generally low.

(B) large-scale urban road network connectivity is high.

The researchers divided 36 big cities according to the city size, and found that the connectivity of large-scale urban road networks was generally high. The average road network connectivity of megacities and megacities is 3.29 and 3.31, respectively, which is generally higher than the average road network connectivity of type I and II megacities of 3.27 and 3.26, as shown in Figure 1.

Figure 1 Distribution of Road Network Connectivity in Cities of Different Sizes

(C) The connectivity of urban road network has a strong correlation with the overall urban form.

According to the overall form of urban road network structure, the researchers divided 36 key cities into "cluster, group and strip". Among them, cluster-like refers to the "cake-spreading" road network with concentrated urban road network structure and radial and annular intersection from inside to outside; Group-like means that the urban road network structure is blocked by mountains, rivers, lakes and seas, so that the urban area presents a number of scattered group-like road networks of different sizes; Strip-like road network refers to a strip-like road network, which is limited by topography and can only be developed in narrow valleys or basins.

According to the measured data of 36 major cities, the connectivity of urban road network in cluster form is high, while that in cluster or strip form is relatively low. Cluster cities, such as Beijing, Shanghai, Chengdu and other 16 cities, are located in plain areas, and the development of urban road network is not limited by topography. The urban trunk road network is composed of horizontal and vertical roads and circular roads, which generally has good connectivity; Group cities, such as Guangzhou, Shenzhen and Hangzhou, and strip cities, such as Xining, Lanzhou and Lhasa, are limited by geographical conditions. Because cities are often divided by water systems or mountains, it is difficult to build urban trunk road networks, and the connectivity of road networks is generally low, as shown in Figure 2.

IV. Summary and Prospect

The connectivity of urban road network is one of the indicators to reflect the accessibility of road network and test the rationality of road network structure. Based on the geographic information data, this paper calculates the connectivity of urban road network in 36 key cities in China. The relevant data results can truly reflect the current situation of road network connectivity in big cities in China, which can be used as relevant indicators for urban road network structure evaluation and provide corresponding reference for urban traffic management, urban planning and construction and other fields.

　　Overseas network February 20 thAccording to Sputnik news agency & radio’s report on the 20th, on the 19th, local time, thousands of Americans marched from Lincoln Memorial to the White House to express their protest, demanding that the United States stop sending weapons to Ukraine and dissolve NATO.

　　In the protest procession, politicians and journalists including former US Congressmen Dennis Kucinich and tulsi Garbad were also included. Everyone demands that the United States stop sending weapons to Ukraine, dissolve NATO and hold peace talks with Russia and other countries to establish a multipolar world.

　　Tara Reade, a former staff member of the US Senate, said, "Our focus has basically shifted from Afghanistan to Ukraine. These problems must stop. Too many people have died." Jimmy Doyle, an American comedian and political commentator, sarcastically said that CNN would not report it at all.

　　A protester from the Pennsylvania Liberal Party held up a sign saying, "No aid, no nuclear weapons". "I came here to avoid nuclear war. I don’t think America should be involved in any war. We should not subsidize, aid, invade or participate. We are very close to nuclear war. If we can’t find a peaceful solution, we must be careful. "

　　Protesters gathered near the White House (Photo: Twitter)

　　Mary Ann Wright, a retired American army colonel and former the State Council official, said that millions of people were injured, killed and their homes were destroyed, which was wrong for both Iraq and Ukraine. She also asked the American people to keep putting pressure on Congress to stop delivering weapons and negotiate instead.

　　The protest was held in front of the Lincoln Memorial, and then the crowd marched to the White House and put forward ten related demands to the US government. (Overseas Network Tommy)
