National Development and Reform Commission: The overall level of infrastructure has been improved by leaps and bounds, and the prospects for new infrastructure construction are improving.

On September 26th, the National Development and Reform Commission held a press conference to introduce the infrastructure.

Meng Wei, spokesperson of the National Development and Reform Commission, presided over the meeting. Jian Zheng, Director of Basic Department of National Development and Reform Commission, Li Mingchuan, Deputy Director of Agricultural Economics Department, Zhang Zhihua, Deputy Director of High-tech Department, and Wen Song, Deputy Director of Planning Department of National Energy Administration attended the conference and introduced relevant information.

Since the 18th CPC National Congress, China has made historic achievements in the development of transportation, energy, water conservancy and new infrastructure. The construction of modern comprehensive three-dimensional transportation system and modern energy system has been accelerated, and the overall level of infrastructure has been improved by leaps and bounds.

According to reports, by the end of 20021,the total mileage of China's comprehensive transportation network had exceeded 6 million kilometers, with 794,000 kilometers of transmission lines of 220 kV and above, and the total length of optical cable lines reached 548 1.3 times, 1.7 times and 1.7 times respectively. China's high-speed railways, long-span bridges, UHV power transmission, third-generation nuclear power, super-large water conservancy projects, new-generation mobile communications, industrial internet and other fields have achieved leap-forward development, and construction technologies such as offshore deep-water ports and large-scale airport projects have entered the world's advanced or leading ranks.

In April this year, the Central Financial and Economic Committee held a meeting, clearly pointing out that infrastructure construction should be comprehensively strengthened. It is necessary to advance moderately, and the layout is conducive to leading industrial development and maintaining national security infrastructure, while grasping the degree of construction advance.

The conference clarified the follow-up direction of investment in key areas such as transportation, energy, new infrastructure and water conservancy. In the field of transportation, we will focus on networking, supplementing the network and strengthening the chain, and strengthen the construction of strategic backbone channels such as going out to Tibet, coastal areas along the river, and new land and sea passages in the west; In the field of energy, a number of major hydropower and nuclear power projects will be promoted. In 2025, the installed capacity of conventional hydropower and nuclear power will reach 380 million kilowatts and 70 million kilowatts respectively.

Infrastructure has formed a very large-scale network.

In the past decade, China's infrastructure construction has made rapid progress.

According to the introduction at the press conference, by the end of 20021,the total mileage of China's comprehensive transportation network had exceeded 6 million kilometers, 794,000 kilometers of transmission lines with 220 kV and above, 548 1 10,000 kilometers of optical cable lines, and the total storage capacity of reservoirs reached 903.5 billion cubic meters, forming a super-large-scale network, with high-speed rail, expressway, power grid and 4G networks ranking first in the country.

In the past ten years, China's infrastructure has also formed extensive coverage, constantly improving the convenience of production and life. High-speed railways cover more than 95% of cities with a population of over one million, expressway covers more than 98% of cities with a population of over 200,000, and civil transport airports cover about 92% of prefecture-level cities. Conditional villages have achieved hardened roads, broadband and direct mail. The penetration rate of tap water in rural areas has increased to about 84%, and the penetration rate of 4G and 5G users has reached about 87%.

In the past ten years, major landmark projects in the field of infrastructure have emerged continuously. Major national projects such as the Hong Kong-Zhuhai-Macao Bridge, Beijing Daxing International Airport and the East Middle Line of South-to-North Water Transfer Project were completed and put into operation; Building the world's first quantum secure communication backbone line "Beijing-Shanghai trunk line"; The Jiquan 1 100 kV DC transmission project with the highest voltage level, the largest transmission capacity and the longest transmission distance in the world was successfully put into operation. 500-meter spherical radio telescope (FAST), fully superconducting tokamak device, Shanghai light source, etc. Leading the world.

In the past ten years, with the help of new technology, the construction of traditional infrastructure and new infrastructure in China has been accelerated. Beijing-Zhangjia high-speed railway has opened a new era of intelligent railway in China. Expressway has achieved "one network" operation, with more than 10 automated terminals completed and put into operation, digital navigation channels basically covering the trunk lines of the Yangtze River and Xijiang River, 234 airports realizing "paperless" convenient travel, and accelerating the construction of a strong smart grid.

In the past decade, innovation infrastructure has been accelerated and optimized. China has built a relatively complete system of major scientific and technological infrastructure. Of the 77 national major scientific and technological infrastructures under construction, 32 have been completed and put into operation, and some facilities have entered the first phalanx in the world. China has continuously accelerated the construction of innovation capability and consolidated the dominant position of enterprise innovation. More than 200 national engineering research centers, 1600 national enterprise technology centers and a number of national industrial innovation centers have been laid out in key areas, and the system of technology development facilities has been continuously improved.

In the past decade, infrastructure investment, as an important starting point for expanding domestic demand, has played a leading role in stabilizing the economy and promoting growth. Taking Beijing Daxing International Airport as an example, the investment in civil aviation is more than 80 billion yuan, and the investment in surrounding transportation and other municipal facilities is 300 billion yuan. Coupled with the input of production factors such as high-end manufacturing and modern service industries gathered around the airport, it has become a huge engine for coordinated regional development.

In the past decade, public utilities in the infrastructure sector have continued to deepen market-oriented reforms. State-owned railway enterprises have completed the transformation of corporate system, the national oil and gas pipeline network company has been established, the competitive power business has been released in an orderly manner, and power grid enterprises have paid more attention to their main business.

Jian Zheng said that while the infrastructure construction in China has achieved great-leap-forward development, it has gradually formed development experiences that meet the requirements of national conditions and the times, such as promoting superior resources in an overall way, taking the people as the center, and adhering to the principle of moderately advanced development.

In the next step, we will accelerate the construction of a complete, efficient, practical, intelligent, green, safe and reliable modern infrastructure system to lay a solid foundation for building a socialist modern country in an all-round way.

There is still a lot of room for growth in investment in these areas.

In April this year, the Central Financial and Economic Committee held a meeting. While affirming that the overall level of infrastructure in China has advanced by leaps and bounds, it is also pointed out that the infrastructure in China has not yet adapted to the needs of national development and security. Strengthening infrastructure construction in an all-round way is of great significance to safeguarding national security, smoothing domestic circulation, promoting domestic and international dual circulation, expanding domestic demand and promoting high-quality development.

Lifeng Liu, a researcher at the Investment Research Institute of China Macroeconomic Research Institute, told the reporter of the 265438+20th Century Business Herald that strengthening infrastructure construction in an all-round way is not only based on the needs of short-term steady growth, but also based on the long-term needs of high-quality development and serving the country's major strategies, and is committed to building a complete, efficient, practical, intelligent, green, safe and reliable modern infrastructure system. Through the construction of networked facilities such as transportation, water conservancy and electric power, new infrastructures such as 5G, artificial intelligence and big data can drive domestic consumption growth and bring more application scenarios and formats. There is also investment demand in leading industry development and national security, which can promote the layout of related industries and tackle the "stuck neck" project.

This meeting introduced the follow-up investment priorities in the fields of transportation, energy and new infrastructure.

Jian Zheng said that the next step will be to implement the "14th Five-Year Plan for the Development of Modern Comprehensive Transportation System" and optimize the transportation infrastructure. Including strengthening the construction of strategic backbone channels such as going out to Tibet, coastal areas along the Yangtze River and new land and sea passages in the west, and building modern railway networks, highway networks, water transport networks, aviation networks and oil and gas pipelines; Strengthen interconnection and integration, and promote the modernization of urban agglomerations and metropolitan areas; Focus on the construction of bottleneck sections and sections to be connected, hub collection and distribution projects, urban internal and external traffic connection, cross-river and sea-crossing key projects, and create conditions for the development of multimodal transport and intermodal transport.

Wen Song said that at present, major projects planned in the Tenth Five-Year Plan are being completed and put into operation one after another, and the effective investment space is being actively expanded. It is estimated that the investment in key energy sectors during the 14th Five-Year Plan period will increase by more than 20% compared with that during the 13th Five-Year Plan period, which will provide a strong impetus for expanding effective investment and promoting the stable operation of the economy.

The carbon-neutral goal of peak carbon dioxide emission makes the energy field a hot investment spot. In addition to accelerating the installation of wind power and photovoltaics, major projects such as hydropower and nuclear power are also accelerating. Lin, dean of China Energy Policy Research Institute of Xiamen University, told the reporter of 2 1 Century Business Herald that by 2030, the total installed capacity of wind energy and solar energy (00059 1) will reach 65,438.02 billion kilowatts, which is not enough to promote the proportion of non-fossil energy to reach 25%. By 2030, China's total energy consumption will still increase, and hydropower, nuclear power and biomass energy will continue to expand in the future.

Wen Song said that it is necessary to increase the construction of new power infrastructure. We will implement renewable energy substitution actions and steadily promote the construction of large-scale wind power photovoltaic bases, southwest hydropower bases and power delivery channels focusing on deserts, Gobi and desert areas. In principle, the proportion of renewable energy transmission is not less than 50%. We will promote the construction of a number of major hydropower and nuclear power projects. In 2025, the installed capacity of conventional hydropower and nuclear power will reach 380 million kilowatts and 70 million kilowatts respectively.

Wen Song also pointed out that infrastructure construction for energy security and supply should be strengthened. Accelerate the improvement of power mutual assistance between networks. By 2025, the capacity of power transmission from west to east will reach more than 360 million kilowatts. Enhance oil and gas supply capacity, improve the long-distance pipeline network system of crude oil and refined oil products, speed up the construction and interconnection of natural gas pipeline network, and expand trunk lines such as west-to-east gas transmission and Sichuan-to-east gas transmission and north-south tie lines. In 2025, the scale of the national oil and gas pipeline network will reach about 2 1 10,000 km. Build five coal supply guarantee bases in Shanxi, Meng Xi, Mengdong, Northern Shaanxi and Xinjiang, and consolidate the foundation of coal and electricity.

The prospect of new infrastructure construction is improving.

New infrastructure construction is also full of imagination, and its connotation will continue to expand with technological breakthroughs and demand upgrading.

According to reports, the "east calculation and west calculation" project launched in February this year has achieved initial results. At present, the construction schemes of computing hub nodes in eight countries have entered the stage of deepening implementation. There are more than 60 new data center projects in the initial area, and the scale of the new data center exceeds 165438+ 10,000 standard racks, with a total investment of more than 400 billion yuan, and the clustering effect of computing power initially appears.

Zhang Zhihua said that the construction of new infrastructure, one end of which is connected with expanding domestic demand and improving people's livelihood, and the other end is connected with technological innovation and industrial development, is of great practical significance for optimizing investment structure and creating new demand for high-quality supply. During the Tenth Five-Year Plan period and even for a long time to come, the investment prospect of new infrastructure construction in China will continue to improve.

Zhang Zhihua said that support for new infrastructure construction will be intensified in the future. Including guiding telecom operators to make overall arrangements for the construction of 5G and optical fiber networks; Improve the network layout of national computing capacity and promote regional coordination and intensive construction; Make good use of medium and long-term loans, local government special bonds and policy-oriented development financial instruments, increase support for new infrastructure construction, and enhance the enthusiasm of social capital to participate in investment; Continue to implement basic network upgrading projects in small and medium-sized cities in the central and western regions, and support the integration of new technologies such as 5G, artificial intelligence and big data into people's livelihood facilities to bridge the digital divide; Accelerate the research on key core technologies in key areas and enhance the resilience of the industrial chain supply chain.
