Abstract: The disconnection between innovation chains and industrial chains has internally led to the long-term existence of the "two worlds paradox" between science and industry, and externally, it has exacerbated the economic and political risks associated with supply chain disruptions and the recurring issue of being hindered by key core technologies. Accelerating the integration of the two chains is urgent. Technology standards not only support industrial collaboration but also play a leading role in technological cooperation. Developing and promoting fundamental, universal, and advanced technical standards around key links and critical areas provides a viable and practical approach to achieving double-chain-integration. However, existing research has paid little attention to the driving role of technical standards. Based on its linkage role of technology standards in the integration, we dedicate to elucidating the theoretical logic and mechanisms through which technology standards drive the integration of innovation chains and industrial chains. We aim to answer the following questions. First, why can technology standards drive the integration between the innovation chain and the industrial chain? What are the rational logic and internal mechanisms? Second, how can technology standards drive the integration between the innovation chain and the industrial chain? What are the process and implementation pathways? This article first takes the connotation and extension of technical standards and double-chain-integration as the premise, and extracts the process mechanism of technology-oriented standard diffusion, demand-driven standard development and two-way synergistic standard bridging. We then analyze the functional realization of dual-chain-integration driven by technology standards from the dimensions of participants, innovation elements and operation space. Finally, we construct multidimensional implementation pathways and operational mechanisms for the integration of both chains driven by technical standards through patent pool formation, strategic knowledge disclosure, and the development of derivative technologies. Based on the strategic needs of China's innovation development and local practical experience, the study reveals the internal law, operation mechanism and realization mode of technology standard-driven integration between the innovation chain and the industrial chain, thus providing a new direction for China to realize scientific and technological self-reliance at a high level. The theoretical and practical contributions of this article are as follows. First, we construct a theoretical model of the double-chain-integration driven by technology standards, and probes into its integration process and mechanism, which helps to form a theoretical innovation on the double-chain-integration. Second, this article innovatively introduces technology standards into the analytical framework of the double-chain-integration, thus helping to expand the theoretical boundaries of technology standardization. The conclusions do not only help to deepen the rational understanding of the double-chain-integration driven by technology standards, but also offer new analytical ideas, diversified decision-making tools and alternative policy insights for the management practices of enterprises and governments.
