Abstract:Promoting the integration of the innovation chain, the industry chain, the capital chain and the talent chain (collectively as "four chains") is an inevitable choice for accelerating the development of new productivity and realizing high-quality development. The integration of the four chains originates from the integration of the innovation chain and the industrial chain, which is the expansion and deepening of the theory related to the synergistic innovation and development of industry and science and technology. Integration of innovation chain and industrial chain is the premise and core of "four-chain" integration, and the focus of integration is to promote the effective transmission of industrial technological needs to the innovation body and accelerate the transformation of cutting-edge technological achievements into real productivity, and the key is to set up a sense of whole-chain innovation and whole-industry-chain innovation and establish the status of enterprises as the main body of innovation. The focus of the integration of talent chain, capital chain and innovation chain and industry chain is to actively guide the flow of talents and capital to the urgently needed and scarce links in the integration and development of innovation chain and industry chain, and the key is to vigorously attract and nurture high-level basic research talents, scientific and technological entrepreneurship leaders and high-skilled talents, as well as to improve the diversified investment mechanism for basic research and to develop "patience capital". The focus of the integration of capital chain and talent chain is to optimize the allocation of talent chain through the capital chain, and the key is to scientifically analyze and forecast the demand of industrial talents and optimize the talent evaluation and incentive mechanism. It is suggested to develop strategic industry development plan and supporting action plan, comprehensively build regional innovation system with enterprises as the main body of innovation, and establish synergistic development mechanism of "industry, science and technology, talents and finance" to indicate the direction, clarify the methodology and establish guarantee mechanism for the integration of the "four chains".
