The General Layout Plan for the Construction of Digital China (hereinafter referred to as the Plan) recently issued by the Central Committee of the Communist Party of China and the State Council proposed that by 2025, an integrated promotion pattern of horizontal connectivity, vertical connectivity and strong coordination would be basically formed, and significant progress would be made in the construction of digital China. By 2035, the level of digital development will be at the forefront of the world, and significant achievements will be made in the construction of digital China. Analysts believe that digital technology will bring more new impetus and opportunities to economic and social development in the future. Digital industry has become a dominant industry. "Building a digital China" is one of the key words for high-quality development. The Plan points out that 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. Accelerating the construction of digital China is of great significance and far-reaching impact on the overall construction of a modern socialist country and the overall promotion of the great rejuvenation of the Chinese nation. "Digital technology is an inevitable element of social development in the information age." Pan Helin, co-director of the Research Center for Digital Economy and Financial Innovation of the International Business School of Zhejiang University, said that at present, the digital industry has become a dominant industry in China, and the rapid development of digital technology provides important opportunities for enterprise transformation and upgrading. According to the data, from 2012 to 2021, the scale of China's digital economy increased from 11 trillion yuan to 45.5 trillion yuan, ranking the second in the world for many years, and the proportion of the digital economy in GDP increased from 21.6% to 39.8%. "The substantial improvement of the quality of the development of the digital economy is mainly reflected in the following aspects: first, systematization, the digital industry should become a comprehensive industrial system with vertical and horizontal connectivity; second, the improvement of digital technology, such as breakthroughs in chips, operating systems and other aspects, to form independent digital technology capabilities. In addition, the digital infrastructure should be improved, and the external environment for the development of digital China will be optimized," said Pan Helin. According to the overall framework of "2522", how to set the layout objectives? The Plan clearly states that the construction of digital China will be arranged according to the overall framework of "2522", that is, to consolidate the "two foundations" of digital infrastructure and data resource system, promote the "five in one" deep integration of digital technology and economic, political, cultural, social and ecological civilization construction, strengthen the "two capabilities" of digital technology innovation system and digital security barrier, and optimize the "two environments" of digital development at home and abroad. Industry insiders believe that the overall framework of "2522" makes the construction path of digital China more concrete and easy to understand. It also makes the specific requirements of the Plan enforceable and helps the construction of digital China enter the fast lane. From the perspective of the "foundation" of digital China, to consolidate the foundation of digital China, we need to open up the main artery of digital infrastructure. The Plan proposes to systematically optimize the layout of computing power infrastructure, promote the efficient complementarity and synergy of computing power between the east and the west, and guide the rational hierarchical layout of general data centers, supercomputing centers, intelligent computing centers, and edge data centers. "Communication, computing power and data market are all infrastructure for the development of the digital economy. These infrastructure have public attributes. We should start to improve infrastructure supporting facilities and promote the accelerated development of the digital economy," Pan Helin said. Last February
