The Fourth Plenary Session of the 20th Central Committee of the Communist Party of China proposed that the prosperity and development of socialist culture should "follow the trend of information technology development" and "promote the digital empowerment and information transformation of cultural construction". Currently, the development of the digital cultural industry, characterized by the integration of digital technology and culture, has become a significant trend in China's cultural construction field. Grasping the scientific connotation and development trend of the digital cultural industry, vigorously improving the modernization level of the digital cultural industry chain, is an important driving force for promoting the construction of a cultural power and the prosperous development of socialist culture during the 15th Five Year Plan period. The emergence of digital cultural industry, in essence, is a market choice for cultural industry to meet the needs of the development of the times under the background that the Internet and digital technology are integrated into all aspects of people's production and life. Its core is to use digital technology to transfer the storage media, expression methods, dissemination methods, and business models of the cultural industry from traditional forms to production and consumption methods that are more suitable for the needs of the times. The core component of the digital cultural industry is cultural and creative content. Whether from digital video to animation games, or from digital publishing to smart tourism, it is the embodiment of the integration and development of "Internet plus" in various fields of the cultural industry. From a global perspective, the combination of digital technology and cultural industries not only enriches the content of the digital economy, but also expands the development space of the cultural industry. The digital cultural industry is showing development trends such as deep integration and industrial interconnectivity. Among them, deep integration is reflected in the fact that the digital cultural industry not only involves the real economy, but also involves productive and life service industries; Industrial interconnection is reflected in: the digital culture industry started from the consumer Internet, and then extended to the supply side. The joint efforts of the consumer side and the supply side formed the current digital culture industry Internet. The digital cultural industry has significant characteristics such as a wide social audience, high product added value, strong industrial driving force, and obvious characteristics of the times, which makes the "digital cultural industry chain" a new topic that urgently needs to be explored in depth. The digital cultural industry chain is an objective chain like interconnected form formed between various departments of the digital cultural industry based on certain technological and economic connections. It covers the entire process of market research, creativity, design, production, trading, consumption, and derivative product development, and has characteristics such as synergy, openness, and dynamic balance. The complete digital cultural industry chain generally includes interrelated dimensions such as supply and demand chain, value chain, product chain, technology chain, and spatial chain. At present, the "modernization of the industrial chain" is playing a more fundamental and supportive role in promoting the construction of Chinese path to modernization. The Third Plenum of the 20th Central Committee of the Communist Party of China proposed to "improve the system for enhancing the resilience and safety level of industrial and supply chains". Vigorously developing the digital cultural industry and enhancing the modernization level of the industrial chain, meeting the high-quality, diverse, and personalized digital cultural consumption needs of the people, continuously improving the happiness and sense of achievement of the people, and enhancing the international influence of Chinese culture in the digital age are urgent requirements for the development of the cultural industry. However, under the current perspective of the industrial chain, there are still bottlenecks and problems in the development of China's digital cultural industry, such as insufficient product chain supply, low added value in the value chain, prominent shortcomings in the technology chain, and the need to optimize the spatial chain. It is necessary to further comprehensively deepen reforms, vigorously improve the modernization level of China's digital cultural industry chain, and continuously explore the path of high-quality development of China's digital cultural industry. Upgrade the product chain of the digital cultural industry and increase the effective supply of products. One is to promote the digital transformation of cultural resources. Vigorously promote the integration and development of cultural resources and digital technology, gradually improve the construction of digital libraries, digital rural libraries, urban and rural electronic newspaper screens and other projects nationwide, and enhance the level of digitalization and intelligence of cultural venues. The second is to increase the innovation of digital cultural content. Emphasize the use of modern advanced digital technology to transform excellent traditional Chinese culture and modern creativity into digital products and services that meet the needs of the times and market development; Strengthen the development of common technologies in the digital cultural industry, optimize the mechanism and policy system for cultural and technological innovation and achievement transformation. The third is to build a complete product chain around excellent cultural IP, expand product portfolio and product line, and enhance digital IP production capacity and value. The fourth is to break through factor constraints, promote cross regional and cross industry optimization of production factors such as labor, capital, technology, and data, improve the total factor productivity of cultural enterprises, and expand the effective supply of digital cultural products and services. Enhance the value chain of the digital cultural industry and improve its ability to create value. One is to expand upstream in the industry chain of research and development design, product creativity, etc. By adopting measures such as digital technology application and business process reengineering, we continuously expand our business upstream in the industry chain, including product creativity, industry standard setting, and product design and development, in order to enhance our competitive advantage. The second is to extend to the midstream of the intelligent manufacturing and other industrial chains. By leveraging data-driven, automated, and intelligent production systems and platforms, core cultural enterprises can promote standardization and customization of digital cultural products, achieving intensive and high-quality production of digital cultural products. The third is to expand downstream in industries such as digital consumption and services. Guide digital cultural enterprises to vigorously apply digital technologies such as big data and blockchain, provide real-time online interaction and intelligent services, continuously innovate cultural content and forms, improve service models, enhance cultural consumption experience, and strive to extend the downstream of the digital cultural industry chain. Innovate the technology chain of digital cultural industry and strengthen the basic guarantee capability. One is to strengthen the research and development of key core technologies. Continuously improving the innovation system of the cultural industry, strengthening the research and development of basic and common technologies in the digital field, and forming more innovative technologies with independent intellectual property rights in key areas and critical links. The second is to establish an industry standard system. Give full play to the guiding and supporting role of standards in the industry, promote the research and development of product, technology, and service standards in fields such as virtual reality and interactive entertainment, and form a standard system for the digital cultural industry. The third is to strengthen the cultivation of digital cultural talents. Innovate the training mode of digital cultural talents in universities and establish a multi-level talent training system; Strengthen the construction of leading talents in digital culture and improve preferential policies for the introduction of high-level talents. Optimize the spatial chain of digital cultural industry and create characteristic industrial clusters. One is to lay out a group of distinctive and highly driving digital cultural industry clusters. Taking the main enterprise of the digital culture chain as the driving force, gathering upstream and downstream small and medium-sized enterprises to supplement and strengthen the chain, and enhancing the competitiveness of the cluster. The second is to innovate the allocation of elements and promote the development of digital cultural industry clusters. Promote the optimization and reorganization of talent, capital, data and other factors in spatial scope, improve the efficiency of factor allocation, form a distinctive development model of digital cultural industry cluster, and optimize the spatial layout of digital cultural industry. The third is to create an information, knowledge, and technology sharing platform and optimize the spatial layout of the digital cultural industry. The digital cultural industry chain has the characteristics of borderless network nodes and infinite extension of the industry chain. The industrial virtual cluster should be a collaborative open network with a platform as the carrier and transparent information. Digital cultural enterprises can share resources and information on the service platform. In addition, it is necessary to unify and clarify the connotation and extension of the digital cultural industry, segment industry types, unify industry classification criteria, and thus form a scientific, reasonable, and complete digital cultural industry chain management system. On this basis, we will strengthen the dynamic supervision of the digital cultural market, continuously innovate regulatory methods, and improve the guarantee and supervision system of the digital cultural industry; Improve legislation on the digital cultural industry, strengthen legislation and protection of digital property rights, and gradually establish a sound legal system covering the entire digital cultural industry chain; Intensify government policy support in areas such as finance, taxation, and banking to promote the modernization of the digital cultural industry chain.
