Built the world's largest 5G network. As of February 2022, China has built and opened a total of 1.506 million 5G base stations, building the world's largest 5G network across all urban areas of the country's municipalities, more than 98% of urban areas in counties and 80% of towns and cities. The total number of 5G base stations in China accounts for more than 60% of the world, nearly 1 times higher than the end of last year. 5G networks have evolved to networks tailored to various industries, with over 2,300 5G field virtual private networks built in key areas such as industries, ports and hospitals, slowly generating a 5G network system adapted to industry needs. 5G terminal users exceed 500 million, accounting for more than 80% of the world. 5G customer penetration exceeds 30%, and user groups has formed a scale.
The scale of cell phone customers and lpwa solutionscellular IoT users continues to expand. By the end of 2021, the total number of cell phone customers in China was 1.643 billion, with a net increase of 48.75 million for the year, and the coverage rate reached 116.3 parts per 1,000 people, up 3.4 parts per 1,000 people from the end of last year. Among them, 5G cell phone customers reached 355 million, accounting for 21.6% of the number of cell phone users. The three basic telecommunications companies developed 1.399 billion cellular IoT customers, a net increase of 264 million for the year, of which IoT terminals for smart utilities, smart manufacturing, smart transportation and other key areas of customers each reached 314 million, 254 million and 218 million.
The growth of mobile Internet user scale has stabilized. By the end of December 2021, the size of China's mobile Internet users reached more than 1.029 billion, enhanced by 43.73 million for the year. Internet dividends were further released to the elderly. As of December 2021, the size of China's elderly Internet users aged 60 and above reached 119 million, with an Internet penetration rate of 43.2%.
Mobile Internet traffic is growing rapidly. 2021, mobile network access traffic reached 221.6 billion GB, an increase of 33.9% over the previous year. The average monthly mobile Internet traffic (DOU) reached 13.36GB/household-per-month, an increase of 29.2% year-on-year. Among them, mobile Internet traffic reached 212.5 billion GB, an increase of 35.5% year-on-year, accounting for 95.9% of mobile Internet traffic.
The development of new mobile terminals is extremely promising. New-style terminals mainly contain drones, AR/VR glasses, robots, etc., and their field terminals that use 5G, including field original equipment, such as AGV (automatic guided transportation vehicle), gateways, medical equipment, heavy machinery, etc. As 5G becomes more and more deeply integrated with the field, the variety of terminals may become more and more diverse.
5G investment drives growth in total economic output. Based on the "China Wireless Economy White Paper 2021" published by China Academy of Information and Communication in October 2021, it is calculated that the size of China's wireless economy in 2020 has exceeded 3.8 trillion, accounting for about 3.8% of China's GDP. The basic forecast is that the size of China's wireless economy will be about $4.4 trillion in 2021. 5G business enables the wireless economy potential to be further released.
5G investment in 2021 is 184.9 billion yuan, accounting for 45.6% of telecom fixed investment ratio. With the deepening of 5G application areas, other sectors of the social economy are also starting to increase their investment in 5G and related ICT technologies. The China Academy of Information and Communications Technology calculates that 5G will directly drive total economic output of $1.3 trillion in 2021, an increase of 33% compared to 2020.
In 2021, the three major systems of industrial Internet network, platform and security will continue to be sound. At the network level, new network modes such as industrial 5G sliced virtual-like private network and hybrid virtual-like private network will be rapidly promoted, and the support capacity of industrial IoT infrastructure application will be upgraded continuously. Platform level, as of December 2021, China has a certain regional and field visibility of industrial network platform more than 150, access to a total of more than 76 million sets of equipment, service enterprises more than 1.6 million. In terms of security, the national industrial network security detection and situational awareness platform has long been connected to all 31 provincial (autonomous prefectures and municipal districts) systems, and the "China-province-company" three-level collaborative industrial network security situational awareness system is basically built.
"The 14th Five-Year Plan includes artificial intelligence as one of the key industries of the digital economy and "frontier technology industry research" technologies, and artificial intelligence has been written into the regional "Fourteenth Five-Year Plan" industrial planning, clear industry development roadmap, to promote the rapid implementation of artificial intelligence infrastructure. Various places actively promote the construction of intelligent computing centers. By the end of 2021, China has long built 7 artificial intelligence computing centers such as Shenzhen and Wuhan, but also Shanghai, Chengdu and other 10 cities newly built or plan to build intelligent computing centers. By the end of 2021, the total scale of data center specification racks in use in China exceeds 4 million racks, which has basically met the requirements of data information storage and calculation rate in various regions and industries.
In 2021, the development of blockchain industry moves into a new stage. Driven by the policy, blockchain-based application innovations continue to emerge, providing strong impetus for the digital transformation of the social economy. In April 2021, the China-ASEAN blockchain public service platform "Gui Chain" was released and fully connected with the new infrastructure of national blockchain and industrial IoT collaborative innovation " At present, it has created multiple application fields such as "blockchain+chain free trade" and "blockchain+electronic license", which will further promote the cooperation of digital economy for ASEAN region.
