Industrial digitization is an important engine for the development of the digital economy and an important source of new driving forces for economic development. Currently, with the deepening development of a new round of technological revolution and industrial transformation, the value of data as a key factor of production is increasingly prominent. The digital transformation of the three industries is constantly deepening, but the dilemma of some enterprises being "unwilling to transfer", "afraid to transfer", and "unable to transfer" still needs to be solved. While improving the top-level design, we should actively promote relevant good experiences and practices, focus on the four key points, accelerate the digital transformation of the industry, and build new competitive advantages. One is to promote the digital transformation of large, small, and medium-sized enterprises by classification. Leading enterprises are not only benchmarks for promoting digital transformation, but also important forces for promoting the transformation of small and medium-sized enterprises. We need to integrate "chain thinking" into industrial digital transformation, focus on "chain owners" enterprises, benchmark international leading levels, carry out integrated application innovation that connects the industrial chain, build digital collaborative platforms, and improve the digital service level of the industrial chain. Small and medium-sized enterprises are the focus and difficulty of digital transformation, mainly facing problems such as high investment and high uncertainty in transformation. To implement the digital transformation partnership action and tailor enterprise transformation solutions. Increase support for discounted loans and other services, explore a "contract based" digital service model of first use, then payment, and profit sharing, and promote small and medium-sized enterprises to "access the internet and cloud". The second is to accelerate the deepening of digital empowerment in the primary, secondary, and tertiary industries. There are significant differences in the digital penetration of the three industries, and the transformation paths are different. It is necessary to implement policies based on the industry to improve the level of digitalization. Decentralized agricultural production, long growth cycle, and many uncontrollable factors make enhancing output stability and improving supply-demand adaptability the key to developing smart agriculture. We need to promote the coverage of smart agriculture in the pre production, mid production, and post production stages, build digital gardens, digital irrigation areas, and smart agriculture (animal husbandry, fishing) farms, continue to promote "digital commerce for agriculture", and promote the organic connection between "small farmers" and "big markets". The manufacturing industry has a wide range of industries, with a high degree of division of labor in the production process, and a comprehensive and full chain collaborative transformation is the core of digital empowerment. We need to develop a roadmap for digital transformation by industry, promote transformation models such as "industrial brain+future factory" and "one chain, one network, one platform", and promote digital transformation throughout the entire product lifecycle. The service industry has significant differences and numerous barriers, and management optimization and quality improvement are the key to digital transformation. We should combine the construction of international consumption center cities and regional consumption center cities to create a batch of smart business districts and digital consumption infrastructure, and prosper new business formats such as shared travel, catering and takeout, and online group buying. The third is to actively cultivate high-energy digital park platforms. Industrial parks are the spatial carriers of industrial agglomeration and the main battlefield of industrial digital transformation. It is necessary to improve the efficiency of digital transformation through virtual and real linkage. Focusing on creating a digital economy industrial park with high standards and levels, we will strengthen the construction and demonstration application of smart networks, and promote the digitalization of facilities such as old factories, warehouses, and commercial buildings
