Abstract: The 15th Five-Year Plan period is a critical phase for China to foster new-quality productive forces and break through the bottlenecks constraining high-quality development.Faced with prominent conflicts such as the disconnection between innovation chains and industrial chains,and barriers to factor flows,as well as an international landscape characterized by increasingly fierce global technological competition,the deep integration of scientific and technological innovation and industrial innovation has become a core means to address development challenges and achieve industrial upgrading towards high-end sectors.It is also an inevitable choice for responding to global scientific-technological rivalry and safeguarding the security of industrial supply chains,and bears great significance for building an independent,controllable,safe and efficient modern industrial system.Based on national actual development conditions,combined with the evolutionary laws of scientific and technological revolutions and industrial transformations and international advanced experience,this paper constructs four integration models:chain-based integration,platform-based integration,demand-driven integration,and integration for future industries.These modelsare both independently adapted to different scenarios and interwoven to form a dynamically complementary innovation ecosystem.To promote the effective implementation of such integration,it is necessary to strengthen the dominant position of enterprises in technological innovation and focus on key fields to tackle core technologies.It is necessary to build concept verification and pilot testing platforms to overcome the “valley of death” in the transformation of scientific and technological achievements,create diversified application scenarios and high-level industrial clusters to optimize spatial carriers for integrated development,and deepen institutional reform and improve the financial support system to provide institutional guarantees and resource empowerment for full-chain integration,thereby facilitating the cultivation of new-quality productive forces and the achievement of high-quality economic development.
