Research on Efficiency Evolution of Data-Driven Integrated Circuit Supply Chain
Strengthening China's integrated circuit(IC)supply chain is a crucial task to promote the new national system and overcome key technologies.Currently,the Chinese IC industry is facing bottlenecks that urgently require supply chain optimization and collaboration to break through technological barriers.In response,this study analyzed the regional efficiency and collaborative coupling structures of listed firms upstream and downstream of the IC supply chain,and explored the spatiotemporal evolution of efficiency across regions.The results showed that the level of supply chain collaboration across municipalities continued to improve,with significant spatial spillover effects and collaborative coupling promoting efficiency.The efficiency of upstream industries were related to the number of externally collaborating firms,while midstream and downstream industries required more internal collaboration.Based on these findings,this study suggested focusing on leading enterprises and cities to develop collaboration models tailored to different industries,thereby improving supply chain efficiency and helping the IC industry break through the technological bottlenecks.
