In Tianjin Binhai New Area, greenhouse tomatoes have sensors, precision irrigation equipment is connected to the intelligent agricultural cloud platform, resulting in better taste and improved yield of tomatoes; In Dayun Town, Jiashan County, Zhejiang Province, villagers sit in the "cloud consulting room" of the health center, and with a click of the mouse, doctors in Grade III hospitals can receive medical services online, sharing high-quality health resources between urban and rural areas; In Nanning City, Guangxi Province, the digital government integration platform has enabled data to run errands for the masses, compressing more than 80% of the business processes of enterprises and people... Today, the small changes driven by the construction of digital China are converging into an era of profound changes in the production and life of Chinese people. Building a digital China is an important engine to promote Chinese path to modernization in the digital era, and a strong support to build a new competitive advantage of the country. Not long ago, the Central Committee of the Communist Party of China and the State Council issued the "Overall Layout Plan for the Construction of Digital China" (hereinafter referred to as the "Plan"), outlining the phased goals for the construction of digital China by 2025 and 2035, indicating the direction and method path for the construction of digital China. Implementing the objectives and tasks proposed in the Plan will comprehensively improve the integrity, systematicness and synergy of the construction of digital China, promote the deep integration of the digital economy and the real economy, drive the transformation of production, life and governance methods with digitalization, and inject strong power into comprehensively promoting the great rejuvenation of the Chinese nation with Chinese path to modernization. Looking back on the past decade, from "3G breakthrough", "4G synchronization" to "5G leadership", digital infrastructure has achieved leapfrog development; The scale of China's digital economy has increased from 11 trillion yuan to over 45 trillion yuan, and the digital transformation in various fields has accelerated; "Palm Office" and "Fingertip Office" have become the standard configuration of local government services, and the efficiency of digital government governance services has significantly improved; The continuously consolidated "digital base", constantly enriched data resources, and increasingly improved data security have made the "information artery" of economic and social development surging, playing an important role in promoting the construction of a new development pattern and a modern economic system, and laying a solid foundation for further promoting the construction of a digital China. Some international observers believe that China can "lead the next wave of global change" because "the massive infrastructure construction, transportation and logistics, promotion of new energy, and digital ecological internet construction required to meet the change are not completed by individual companies alone, and national power plays a very important role." In this regard, China has an "indispensable advantage.". China has unique political advantages and significant institutional advantages, and can conduct top-level design across regions, departments, and industries, providing a strong digital infrastructure for the construction of digital China; China has the advantage of a large-scale market and a complete industrial system. Whether it is the consumer Internet or the industrial Internet, it can find rich application scenarios and solid upstream and downstream support, which is conducive to diluting investment costs
