Construction of digital infrastructure in our country

In October 2021, a collective learning focused on "Promoting the healthy development of China's digital economy" was held in Zhongnanhai. "We should speed up the construction of new infrastructure, strengthen the strategic layout, accelerate the construction of high-speed ubiquitous, heaven and earth integration, cloud network integration, intelligent agile, green, low-carbon, safe and controllable intelligent comprehensive digital information infrastructure, and open up the information 'main artery' of economic and social development." 

 "We will accelerate the construction of new infrastructure and upgrade the level of traditional infrastructure," the meeting said. Promoting the development of traditional infrastructure and new infrastructure in a coordinated way, between the "new" and "old", is the explosion of development vitality and the transformation of development momentum.

Facing the new era, a series of deployments have been launched. The 14th Five-Year Plan for National Economic and Social Development of the People's Republic of China and the Outline of the 2035 Vision and Goals list "Accelerating the construction of new infrastructure" as a special section; The "14th Five-Year Plan for National Informatization" proposes to build a digital infrastructure system that is ubiquitous and intelligent. The 14th Five-Year Plan for the Development of Digital Economy proposes to optimize and upgrade digital infrastructure; The Outline of the Strategic Plan for Expanding Domestic Demand (2022-2035) calls for the systematic layout of new infrastructure. Various localities have set up target plans for the completion of 5G base stations in the New Year to systematically promote the construction of digital infrastructure.

From the central to the local level, a series of specific arrangements have been intensively implemented, and digital infrastructure projects that benefit the present and focus on the future have been accelerated, and the "major arteries" of information have continued to open up, activating a pool of spring water in the economy. With the strong support of digital infrastructure, China's digital economy will reach 45.5 trillion yuan in 2021, ranking second in the world.

Create new driving forces and advantages for development, and open up the information artery for economic and social development

"If you want to be rich, build roads first", this is a simple truth passed down by the Chinese people and witnessed by their own eyes. In the digital age, this "road" is showing new meaning and creativity.

In recent years, China has continuously strengthened the layout of digital infrastructure, coordinated the construction of network infrastructure, computing infrastructure, and application infrastructure, and vigorously promoted the systematic development and large-scale deployment of digital infrastructure, which has achieved remarkable results and injected strong impetus into the high-quality development of China's economy.

-- Network infrastructure has developed by leaps and bounds

"Officially opened!" With the opening of the 5G test base station in Dulongjiang Township, Yunnan Province, and the successful dial-up of the first 5G high-definition video call in the province, "Internet + education", "Internet + medical care", "Internet + e-commerce" and so on have landed in Dulongjiang Township, so that the Dulong nationality, which was the latest to enter modern society, has realized the dream of informatization "jumping to a thousand years".

From the city to the countryside, from the mine to Mount Everest, from the island to the Gobi, climbing towers, installing antennas, laying optical cables... China's network infrastructure builders have braved difficulties and overcome difficulties to create the world's largest 5G high-quality network covering the whole country with advanced technology and good quality.

From 1G blank, 2G follow, to 3G breakthrough, 4G and run, and then to the number of 5G base stations, independent networking scale, terminal connections are ranked first in the world, why can China 5G lead the world?

The key lies in playing the "first hand chess" and playing the "initiative battle" well.

As early as 2013, China established a 5G promotion group (IMT-2020 Promotion Group) composed of "production, study, research and use" parties to promote 5G technology research and development, verify technical solutions, and support the formulation of international standards.

Three years later, in January 2016, China announced the full launch of 5G technology research and development experiments, and planned to conduct 5G key technology tests, 5G technology solutions and system verification in phases during the three years from 2016 to 2018. In July, the General Office of the Communist Party of China Central Committee and The General Office of the State Council issued the Outline of the National Informatization Development Strategy, which clearly proposed that by 2020, the research and development and standards of fifth-generation mobile communication (5G) technology will make breakthrough progress.
