Construction of digital infrastructure in our country

All regions and departments earnestly implement and further promote the large-scale deployment and application of IPv6; All kinds of network and information enterprises responded positively, accelerated the pace of IPv6 upgrading, and increased the volume of drainage... By December 2022, China has applied for 67,369 IPv6 address resources, ranking first in the world. The number of active IPv6 users in China reached 728 million. China's network infrastructure already fully supports IPv6.

Having an independent satellite navigation system is an important guarantee for the security and development of a major country.

 A global navigation satellite system independently built and operated by China has been fully completed.

This is an unprecedented "Chinese path". From the establishment of the project in 1994 to the completion of the Beidou No. 1 system in 2000, from 2012 to officially provide regional services to the global service in 2020... In the past 26 years, China's Beidou has explored a development path with Chinese characteristics from scratch, from good to excellent, from active to passive, and from regional to global, making China the third country in the world to independently own a global satellite navigation system.

Nearly 8,000 Beidou terminals of various types have been applied and promoted in the railway field; In 2021, the number of domestic smartphone shipments supporting BDS has reached 324 million, accounting for 94.5% of the total domestic smartphone shipments. Based on Beidou's high-precision lane-level navigation function, it has been successfully piloted in 8 cities and gradually popularized throughout the country. Beidou application has been deeply integrated into the overall development of the national economy and has become a time-space cornerstone and an important engine to promote economic and social development.

-- Computing infrastructure provides new driving force for the development of the digital economy

High-speed servers, round-the-clock data centers, fast and smooth network transmission... Running bytes and massive data are converging into a huge force for the development of digital China.

From 2017 to 2021, China's data production has increased from 2.3ZB to 6.6ZB, and in these three years, China's data production has maintained an annual growth rate of about 30%. Like water conservancy in the agricultural era and electricity in the industrial era, computing power has become an important productive force for the development of the digital economy. The data shows that for every 1 percentage point increase in the average computing power index, the digital economy and GDP will increase by 3.3‰ and 1.8‰, respectively.

In recent years, with the acceleration of digital transformation and upgrading in various industries, especially the rapid popularization and application of new technologies such as 5G, the total amount of data has exploded, and the demand for data resource storage, calculation and application has increased significantly, and the demand for creating a new computing network system is extremely urgent.

Follow the law of development, comply with the needs of the industry, a series of top-level design and planning intensive launch. The "Guiding Opinions on Accelerating the Construction of a National Integrated Big Data Center Collaborative Innovation System" proposes to optimize the construction layout of data centers; The "National Integrated Big Data Center Collaborative Innovation System Computing Hub Implementation Plan" requires improving the level of cross-regional computing power scheduling...

In February 2022, the National Development and Reform Commission, the Central Cyberspace Administration and other departments jointly issued a notice, agreeing to start the construction of national computing hub nodes in eight places, including Beijing-Tianjin-Hebei, Yangtze River Delta, Guangdong-Hong Kong-Macao Greater Bay Area, Chengdu-Chongqing, Inner Mongolia, Guizhou, Gansu and Ningxia, and planning 10 national data center clusters. At this point, the "East number and West calculation" project was officially launched, opening a new chapter in the cross-regional overall layout of China's territorial space computing resources.

China's first computing town opened in Hangzhou, Zhejiang Province; Chengdu Intelligent Computing Center, Lanzhou new Computing Industry Demonstration Center, Yellow River Basin ecological environment computing Center and so on have been launched; Tencent, Huawei, Ali and other network and information enterprises accelerate the landing project in the national computing hub node...... Stepping on the drumbeat of the "East count West count" project, the national computing power hub node adds a new engine frequently, and the computing power agglomeration effect in China has initially appeared.

In line with the development of The Times, make good use of new production factors of data and new productivity of computing power, and let data factors fully flow and data vitality fully stimulate, the Chinese economy is ushering in a broader blue ocean. At present, the construction plans of eight national computing hub nodes have entered the deepening implementation stage, and the scale of new data centers has exceeded 1.1 million standard racks. There are 497 ultra-large and large-scale data centers and 20 intelligent computing centers in use nationwide. The proportion of data centers in the western region increased steadily, and the national computing power structure was gradually optimized. A number of national open innovation platforms for new generation artificial intelligence public computing power have been built; The computing infrastructure has reached the world's leading level.
