人工智能渗透率与链主企业关键核心技术突破OACHSSCD

Based on the theories of general-purpose technology and knowledge production function,this paper examines the impact of AI penetration rate on key core technology breakthroughs in chain-leading enterprises and explores its underlying mechanism by using panel data of Chinese A-share listed companies.A two-way fixed effects model and mediation effect analysis are employed in the empirical study.The results show that AI penetration rate significantly promotes breakthroughs in key core tech-nologies among chain-leading enterprises.The innovation efficiency of R&D personnel plays a partial me-diating role in this process.In addition,market share exhibits a negative moderating effect,indicating that the empowering effect of AI is more pronounced in chain-leading enterprises with relatively lower market shares.The findings provide empirical evidence for understanding how AI supports technological breakthroughs of core firms within industrial chains and offer implications for promoting the deep inte-gration of AI and enterprise innovation activities.
