Ministry of Industry and Information Technology: Some key technologies such as optical communication equipment and optical fiber and cable have reached the international advanced level

On June 14, the Propaganda Department of the CPC Central Committee held a series of themed press conferences
on "China's Decade".
At the meeting, Han Xia, chief engineer of the Ministry of Industry and Information Technology, introduced the development and achievements of the information and communication industry in the past ten years, which mentioned that China has built the world's largest and most complete optical communication industry system, optical communication equipment, optical module devices, optical fiber and cable and other key technologies have reached the international advanced level, and a number of global leading enterprises
have emerged.

Since the 18th National Congress of the Communist Party of China, under the guidance of Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era, the information and communication industry has achieved leapfrog development, and its strategic, fundamental and pioneering role in the overall situation of economic and social development has become increasingly prominent, providing a solid foundation and strong support
for accelerating the construction of a manufacturing power, a network power and a digital China.
It is mainly manifested in five aspects:

First, the infrastructure has been improved by leaps and bounds from copper lines to optical fibers, from 3G popularization to 5G commercialization
.
Build the world's largest and most technologically advanced network infrastructure
.
The historic completion of the "optical into copper retreat" transformation project, all prefecture-level cities have been fully built as optical network cities, 100 Gigabit and above access rate users have emerged from scratch, accounting for 93.
4%, and the number of gigabit users has exceeded 50 million
.
The scale of 4G base stations accounts for more than half of the global total, the number of 5G base stations has reached 1.
615 million, and the number of 5G mobile phone users has exceeded 400 million
.

Second, breakthroughs in key core technologies have been accelerated, and the strength of the technology industry has been significantly enhanced
.
Mobile communication technology from "3G breakthrough" and "4G synchronization" to "5G leading", the proportion of 5G standard essential patents declared by Chinese enterprises has reached 38.
2%.

The world's largest and most complete optical communication industry system has been built, and some key technologies such as optical communication equipment, optical module devices, optical fiber and cable have reached the international advanced level, and a number of global leading enterprises
have emerged.

Third, innovative applications continue to expand from the consumer field to the production field, forming the world's largest, most active and most potential digital service market
.
Internet applications have been fully popularized, the annual transaction scale of mobile payment has reached 527 trillion yuan, the new economic form has created more than 20 million flexible jobs, and the cumulative number of 5G industry application cases has exceeded 20,000.

The industrial Internet innovation and development strategy has been deeply implemented, and a "Chinese solution" that matches the development stage of the manufacturing industry and is parallel to "making up classes, upgrading and innovation"
has been created.

Fourth, information services are more high-quality and cheap, and digital convenience is shared by the people
.
China has historically realized the "broadband connection between villages and villages" in administrative villages, the proportion of primary and secondary schools with broadband has increased from 25% to 100%, and telemedicine has covered all counties
that have been lifted out of poverty.
The average download rate of broadband networks has increased by nearly 40 times, and the average tariff of mobile network traffic has been reduced by more than 95%.

The communication itinerary card has provided nearly 60 billion public welfare inquiry services, which has strongly supported the normalization of epidemic prevention and control and the smooth travel
of the people.

Fifth, the industry management and security guarantee system continue to be optimized
.
A new regulatory mechanism based on credit management has been gradually established, and enterprise business compliance, industry ecological openness and user satisfaction have all been significantly improved
.
Hot and difficult issues such as telecom network fraud have been effectively addressed, and the number of spam SMS user complaints has dropped to a record low
.
The national network infrastructure security guarantee capability has been comprehensively enhanced, the data security management system in the field of industry and information technology has been initially formed, and the comprehensive strength of the network security industry has been rapidly improved
.

The Ministry of Industry and Information Technology said that in the next step, we will deeply implement General Secretary Xi Jinping's important thought on network power, comprehensively strengthen the construction of new information infrastructure, promote the deep coverage of 5G networks, implement the 5G application "sail" action plan, accelerate the large-scale application of emerging technologies such as 5G, continue to expand industrial opening and cooperation, and help high-quality economic development and continuous improvement
of people's livelihood.
