In the digital age, technology and culture are the twin engines of social progress. The digital culture industry, centered on creative cultural content, relies on digital technology for creation, production, distribution, and service provision. It is characterized by rapid technological upgrading, digitized production, network-based distribution, and personalized consumption, promoting the cultivation of new supply and stimulating new consumption. The industrial chain is a link-like connection among various industries, formed by an organic mix of five dimensions: enterprise chain, value chain, product chain, technology chain, and spatial chain. It covers the entire process of product production or service provision, from raw material production, technology R&D, intermediate product manufacturing, and terminal product manufacturing, to distribution and consumption. It represents a unified structure of industry organization, production process, and value realization.
