Develop a modern infrastructure system

来源: | 作者:佚名 | 发布时间 :2023-12-16 | 502 次浏览: | Share:

Infrastructure, including traditional infrastructure such as transportation, energy, water conservancy and logistics, as well as new infrastructure with information networks as the core, plays a strategic, basic and leading role in the overall development of the country. The Outline proposes that during the "14th Five-Year Plan" period, we should promote the construction of traditional infrastructure and new infrastructure in a coordinated way, and build a modern infrastructure system that is systematic, efficient and practical, intelligent and green, safe and reliable.

I. Major achievements of the 13th Five-Year Plan Period

During the "13th Five-Year Plan" period, the layout of China's infrastructure network has continued to improve, the overall quality has been significantly improved, the comprehensive efficiency has been significantly improved, the institutional reform has been steadily advanced, and the formation of a super-large-scale infrastructure network has strongly supported and led economic and social development.

First, the advantages of network scale are prominent. The "13th Five-Year Plan" period is a key period for China's infrastructure network to accelerate and improve. The total length of optical cables increased from 24.86 million kilometers to 47.5 million kilometers by the end of 2019; the installed power generation capacity increased from 1.53 billion kilowatts to 2.01 billion kilowatts; and the routing of 220 kilovolt or above power lines increased from 609,000 kilometers to 755,000 kilometers. The length of oil and gas pipelines has increased from 109,000 kilometers to 150,000 kilometers; the total storage capacity of reservoirs has increased from 858.1 billion cubic meters to 903.5 billion cubic meters; the effective irrigated area of farmland has increased from 65.87 million hectares to 68.27 million hectares, accounting for about one-fifth of the world's total irrigated area; and the overall carrying capacity of urban infrastructure has been continuously enhanced. The operating mileage of high-speed railways, the operating mileage of expressways, the operating mileage of urban rail transit, the number of berths of 10,000-ton class and above at ports, the installed power capacity, the scale of the power grid, and the scale of the fourth-generation mobile communication (4G) network all rank first in the world.

Second, the service capacity has been continuously improved. During the "13th Five-Year Plan" period, China's passenger turnover increased from 3 trillion person-kilometers in 2015 to 3.5 trillion person-kilometers in 2019, and the cargo transport volume and turnover increased from 41.7 billion tons and 17.8 trillion ton-kilometers in 2015 to 47 billion tons and 19.9 trillion ton-kilometers in 2019, respectively. Railway passenger turnover and freight volume, highway passenger and freight volume and freight volume, waterway freight volume and freight volume rank first in the world. The transmission capacity of "west-east power transmission" increased from 140 million kilowatts at the end of 2015 to 240 million kilowatts at the end of 2019, and the mileage of natural gas main pipeline network increased from 64,000 kilometers in 2015 to 94,000 kilometers in 2019. The East-central route of the South-to-North Water Diversion Project has diverted more than 30 billion cubic meters of water, directly benefiting more than 100 million people. Information services cover more areas and benefit more people. The number of mobile communication users and the number of Internet users increased from 1.27 billion and 680 million in 2015 to 1.6 billion and 830 million in 2019, ranking first in the world. Urban public service indicators such as public water supply penetration rate, gas penetration rate and sewage treatment rate generally exceed 90%.

Third, the level of innovation has significantly improved. During the "13th Five-Year Plan" period, China has basically formed a complete and complete set of technical equipment system, and has a number of technological innovation achievements with independent intellectual property rights. High-speed railways, long-span Bridges, UHV power transmission, super large water conservancy projects, a new generation of mobile communications, a new generation of Internet and other technological fields have achieved leap-forward development. China has completed and actively operated the world's first quantum secure communication backbone line "Beijing-Shanghai Trunk Line", and its construction technologies such as offshore deep-water ports, regulation of giant estuaries and waterways, and large-scale airport projects have entered the world's advanced or leading ranks, forming a full-chain infrastructure industrial system from planning consultation, engineering design, financing, construction, operation and maintenance. The development of 5G, artificial intelligence and other new infrastructure is accelerating; the application of big data, cloud computing and blockchain in traditional infrastructure is accelerating; and the level of international connectivity is steadily improving.
