Abstract: The four chain integration of innovation chain, industry chain, capital chain, and talent chain is the most fundamental and core issue in building a modern industrial system, and is a standard equation for industrial growth. The four chain integration ultimately refers to the effective allocation of production factors in accordance with modern market mechanisms. The premise for the integration of industrial chain and innovation chain is to distinguish between scientific innovation and technological innovation. The integration of industrial chain and capital chain should attach great importance to the issue of asset shortage in the new shortage era, and guide social funds to enter the capital market. The key to integrating the industrial chain and talent chain is to enable industrial workers to live a decent social life. Distinguishing the nature of innovation and the source of funding is the foundation for the integration of the innovation chain and the capital chain. The integration of innovation and talent chains requires the creation of an education and innovation environment where talents emerge in large numbers. Getting the incentive mechanism right is the most important issue in integrating the capital and talent chains.
