Since the formal proposal to build the "Digital Silk Road" in 2017, China has continued to strengthen cooperation with countries along the "Belt and Road" in cutting-edge fields such as digital economy, artificial intelligence, nanotechnology, quantum computers, etc., to promote the construction of big data, cloud computing, smart cities and other fields, and constantly promote the innovative development of the "Belt and Road" construction. Recently, foreign media have noticed that the "Digital Silk Road" advocated by China helps relevant countries promote the construction of digital infrastructure, improve Internet penetration, and promote digital infrastructure connectivity, creating new opportunities for economic growth and digital transformation of relevant countries. Sharing the dividend of digital technology development "As part of the Belt and Road Initiative, the" Digital Silk Road "reflects China's goal of developing digital infrastructure at home and abroad." The website of the Australia East Asia Forum recently said that "the world has witnessed China's digital transformation progress in telecommunications, artificial intelligence, satellite navigation systems, submarine optical cables, monitoring systems and other fields. With the accelerated development of the" Digital Silk Road ", China has further promoted overseas digital projects and high-tech investment." To promote the construction of the "Digital Silk Road", China has a good industrial foundation and broad market space. According to the data of the Ministry of Industry and Information Technology of China, from 2017 to 2021, China's digital economy will grow from 27 trillion yuan to more than 45 trillion yuan, ranking the second in the world, with a compound annual growth rate of 13.6%. The proportion of digital economy in GDP has increased from 33% to 39.8%. The Digital China Development Report (2021) released by the State Internet Information Office of China shows that China's digital technology innovation capability has rapidly improved in recent years. China's artificial intelligence, cloud computing, big data, blockchain, quantum information and other emerging technologies have become the world's first echelon. "China has the necessary infrastructure, which is an important advantage for China to develop the digital economy." According to experts quoted on the website of Spanish newspaper El Pais, 5G network is one of the examples of China's digital economy development, which is crucial to the development of cloud computing, promotion of "Internet of Things" and other commercial applications. In recent years, China's digital economic cooperation with countries and regions along the "Belt and Road" has continued to deepen. At present, China has signed a memorandum of understanding on "Digital Silk Road" cooperation with 17 countries, established a bilateral cooperation mechanism of "Silk Road E-commerce" with 23 countries, and built 34 cross-border land cables and several international submarine cables with neighboring countries. "China has made efforts to solve complex problems related to the digital economy, which can bring solutions to global development." According to an article published on the official website of the World Economic Forum, "given that China has successfully enabled 1 billion people to access the Internet in the past few decades, China's initiative must have much to learn and share." Patrice Cairne, the chairman and CEO of Thales Group, said that China's new generation of information and communication technology has been developing constantly, and new technologies such as 5G, cloud computing, big data, the Internet of Things, and artificial intelligence have accelerated their integration with various industries, which has strongly promoted the digitalization, networking, and intelligence of industries, benefiting multinational enterprises.
