How to better promote the development of the digital economy with 5G? What new opportunities and challenges will the 5G era bring?

TC-OAH061 During the World 5G Conference on November 21, experts from many countries and many fields gathered together to discuss the changes that 5G will bring to the digital economy and global industrial development.

5G and the digital economy are mutually reinforcing

Data from IHS Markit shows that by 2035, the economic output created by 5G for the world will reach $12.3 trillion, accounting for 4.6% of global real output.

“Almost all the world’s population lives in a mobile world, and the mobile economy supports the development of the digital economy.” Wu Hequan, academician of the Chinese Academy of Engineering, introduced that with the gradual TC-OAH061 popularization of 5G, it is expected that by 2025, China will have 430 million 5G connections, becoming the world’s largest 5G market, and 5G users will reach 28% of the number of mobile users in China, accounting for 1/3 of the global total.

A big market means a bigger economic engine. According to the estimates of the China Academy of Information and Communications Technology, 5G will directly drive China’s total economic output of 10.6 trillion yuan from 2020 to 2025, economic value added of 3.3 trillion yuan, and create 3 million new jobs.

“The development of 5G will form a value ring relationship with the digital economy.” Wu Changqi, a professor at Peking University’s Guanghua School of Management, believes that the digital economy combines supply-side adjustment TC-OAH061 and demand-side changes, aiming to solve social problems in the fields of national defense, agriculture, industry, finance, and further realize the role of network security and government public policies. 5G communication technology and integrated circuit related technologies support the Internet of Things, big data, artificial intelligence and other technologies, “5G and the digital economy promote each other.”

David Bartosh, a researcher at the German Science Foundation and a professor at Beijing Foreign Studies University, also stressed that 5G development can help mankind solve many outstanding problems, “If we use it well, it will push us forward and play a positive role in the digital economy, environment and climate.”

Security or the biggest new challenge

When it comes to the new challenges that the 5G era will bring, the focus of Zhou Hongyi, chairman and CEO of 360 Company, is always: “Is 5G safe?”

TC-OAH061 Zhou Hongyi believes that 5G itself is a safer new generation of network infrastructure, and the 5G core network has added many new security features, such as user privacy protection, vertical local area network, and network slice secondary authentication. However, the pan-5G security brought about by 5G+ will be a major challenge.

“Many 5G+ scenarios, such as 5G+ industrial Internet, 5G+ vehicle networking, 5G+ smart city, will bring more and updated attack surfaces.” Zhou said cyber warfare will be the biggest threat in the era of great security.

Zhao Zhiguo, director of the Network Security Administration Bureau of the Ministry of Industry and Information Technology, also believes that the network function virtualization, network slicing technology and network edge computing and other related technologies introduced by 5G have further enhanced the connectivity of the network, the flexibility and personalization of network services, but also brought new security problems and uncertainties.

TC-OAH061 “5G, like AI, both face the challenge of cybersecurity vulnerabilities.” Zheng Nanning, academician of the Chinese Academy of Engineering, mentioned that network security, information security, and security issues at all levels of society are the focus of common attention of academia, industry, government and other industries.

“Innovation leads and actively promotes the development of cybersecurity technology, and technological innovation is the driving force to achieve sustainable development of cybersecurity.” Wang Xiujun, chairman of the China Cyberspace Security Association, suggested that it is necessary to increase investment in the research and development of 5G security technology, promote key technology research, and formulate and improve 5G related technical standards. At the same time, strengthen the construction of outstanding talents, stimulate the vitality of innovation, actively use artificial intelligence, big data and other new technologies to enable cybersecurity, and constantly improve the risk response ability of cybersecurity.

Zhao Zhiguo believes that it is necessary to comprehensively establish the core system of 5G network security, and systematically plan the construction of 5G security system from multiple perspectives such as policy management system, technical support capability, technical standards and specifications, and industrial research. At the same time, through the construction of national network security industrial parks and network security education, further promote the integration of resources and optimal allocation through application pilot demonstrations, promote the innovation and application of 5G security technology, and improve the level of 5G security technology guarantee.
