In recent years, China has accelerated the construction of information infrastructure with the "Eastern Data and Western Computing" project as the traction, and provided new growth points for economic growth and helped high-quality economic development through 'new infrastructure' such as 5G construction, new energy, cloud computing, and industrial Internet.
After 20 years of vigorous development, China's data center industry has continued to evolve and upgrade, and has generally entered a mature stage, and ultra-large data centers have become the focus of the industry layout. Data shows that driven by the two-wheel drive of market supply and demand, the scale of China's data center market continues to grow, and the scale of China's data center market will be about 190 billion yuan in 2022, with an average annual compound growth rate of 30% in the past five years. Based on the favorable and demand of the current macro environment and the life tension of the data center industry, it is expected that the IDC industry will show a trend of clustering, low-carbon construction and service computing power in the future. 
The main arteries of digital infrastructure are gradually being openedIn recent years, a series of top-level designs, such as the "14th Five-Year Plan" and the "Overall Layout Plan for the Construction of Digital China", have been promulgated, clearly proposing to open up the main arteries of digital infrastructure, optimize the construction layout of data centers, and improve the level of cross-regional computing power scheduling. At present, the construction of 8 national computing hub nodes has been started, and 10 national data center clusters have been synchronously arranged. The process of technological and industrial transformation continues to accelerate, and the construction of "dual gigabit" networks represented by gigabit optical networks and 5G will be accelerated, which will further consolidate the "digital foundation" that supports the vigorous development of the digital economy and provide strong support for the digital transformation of all walks of life. The Ministry of Industry and Information Technology has notified the construction of "gigabit cities" in 2022, and 110 cities across the country have reached the gigabit city construction standard. Data show that in the first half of this year, China's investment in new infrastructure construction increased by 16 percent year-on-year2%, of which investment in 5G and data centers increased by 131%。As the core physical carrier of computing infrastructure, data centers have been a hot topic for investment in the field of information and communication in recent years. According to data from the Ministry of Industry and Information Technology, in 2022, the total scale of data center racks in use in China will exceed 5.9 million standard racks, the scale of servers will be about 20 million, and the average annual growth rate of data center storage capacity will exceed 50%. At present, the number of national new-generation artificial intelligence innovation and development pilot zones has reached 17, and the world's largest, technologically advanced and high-performance digital infrastructure has been built, and the overall level has been improved by leaps and bounds. Data centers are in transitionWith the wide application of digital technologies such as artificial intelligence, cloud computing, and blockchain, the strategic role of the data center industry in social and economic development has become increasingly prominent as the triple carrier of digital facilities, digital energy, and digital technology. For data centers in the construction stage, the construction and integration of the infrastructure layer greatly affects the stable operation and sustainable development of the data center in the future. As an important stage of development of the whole life cycle, data center infrastructure integration has been continuously endowed with new connotations and digital intelligence value in the computing era. With the increasing importance of data center construction and integration quality, data centers are developing towards the scale of the service market, which has also promoted the digital technology innovation of the whole life cycle of the industry. Recently, the "Data Center Infrastructure Integration Guide" was officially released, which focuses on the "Technical Requirements for Data Center Intelligent Construction Capability Maturity Assessment" and "Artificial Intelligence-based Data Center Energy-saving Technical Requirements", starting from the four major development trends of data center life cycle construction integration and prefabrication, construction and deployment of high density, intelligent construction and delivery, and low-carbon construction and operation. The technical efficiency released by the integration of digital platforms includes the practical experience of some enterprises in carrying out infrastructure integration. By summarizing the market demand and development trend of data centers in typical industries, this paper outlines the data center integration industry map of the Internet, finance, and government affairs industries, aiming to help the high-quality implementation of infrastructure construction and integrated digital intelligence application scenarios in key areas. The "Data Center Infrastructure Integration Guide" points out four major trends in the integrated development of data center infrastructure: construction integration tends to be prefabricated, construction and deployment tends to be high-density, construction and delivery tend to be intelligent, and construction and operation tend to be low-carbon. At the same time, after 20 years of development, China's data center industry is generally mature. The "Guiding Opinions on the Construction of AI Data Center Networks" has also been successfully established, aiming to promote the digital and intelligent transformation of the industry, promote industrial upgrading and cooperation, and provide a reference for various industries to build data center networks for the AI era. It can be said that the understanding of industrial development inside and outside the industry is also undergoing major changes, from "high-speed" to "high-quality", from "demand-only" to thinking from green, safe, fine operation and many other aspects. Green and low-carbon has become the main theme of construction and operationData centers generally require uninterrupted operation throughout the year, with an annual operation time of 8,760 hours. In the context of the explosion of data and computing power demand in the whole society, the power consumption of data centers will inevitably increase rapidly. With the rapid growth of data centers around the world, energy efficiency has become a hot topic of concern in the industry. According to the Institute of Cloud Computing and Big Data of the China Academy of Information and Communications Technology, by 2030, the power consumption of China's data centers will exceed 380 billion kilowatt hours, and if renewable energy is not used, carbon emissions will exceed 200 million tons. In 2021, the total revenue of China's data center market will reach 150 billion yuan, and in the long run, China will still build many new data centers, and larger data centers will have higher energy efficiency, and the year-on-year growth rate of domestic data centers will remain at about 30% in the future. PUE is a metric that evaluates the energy efficiency of a data center. The closer the PUE value is to 1, the greener a data center is. Policy documents such as the 14th Five-Year Plan for the Development of the Digital Economy and the Three-Year Action Plan for the Development of New Data Centers (2021-2023) have made arrangements for promoting the construction of green digital centers, including "accelerating the energy-saving transformation of data centers and continuously improving the level of renewable energy utilization in data centers" and "reducing the PUE of new large-scale and above data centers to 1 by the end of 2023."3 below" and so on. Recently, many places are actively deploying green and low-carbon technologies and products, increasing the use of renewable energy, and accelerating the construction of green data centers. According to the "Guiding Opinions of Shanghai Municipality on Promoting the Unified Scheduling of Computing Resources", by 2025, the proportion of green computing power in new data centers will exceed 10%;The comprehensive PUE of new large-scale data centers in agglomeration areas decreased to 1Within 25, the green and low-carbon level reaches 4A or above. Controlling the energy consumption of data centers is not only related to the cost of computing services, but also to the core development requirements of the country's carbon emissions. A number of data center companies in China have announced that they will achieve the goal of "carbon neutrality" around 2030. There are three ways to reduce carbon emissions: using technical means to improve energy efficiency (reducing PUE value);Purchase of green energy (hydro, wind, solar, etc.);Strengthen the comprehensive energy reuse (waste heat utilization) of data centers and cities. As data center companies, the high cost of electricity and land has also prompted them to actively improve their energy efficiency and actively embrace green energy. FinallyDigital infrastructure is becoming an important area of "carbon reduction", and actively introducing green and low-carbon technologies and products, increasing the use of renewable energy, and accelerating the construction of green data centers have become the necessary paths for local governments and related enterprises. It can be said that only by strengthening the application and innovation of green computing technology and promoting the green and low-carbon development of the computing power industry can we continue to stimulate the empowerment effect of computing power.
