供应链创新何以驱动城市创业OACHSSCD

As global supply chains undergo rapid restructuring,the establishment of stable and efficient supply chain systems has become increasingly important for fostering urban entrepreneurship.However,the structural inef-ficiencies embedded in traditional supply chain systems not only raise the costs of entrepreneurship but also dampen entrepreneurial incentives,thereby suppressing urban entrepreneurial activity.In 2018,China launched the supply chain innovation and application pilot program,aiming to integrate information technologies with supply chain man-agement and build an efficient,coordinated,and controllable modern supply chain system.By improving industri-al-chain coordination and resource allocation efficiency,the program aims to reshape the institutional environment for entrepreneurial activities.Using city-level data from 2007 to 2023 and exploiting the pilot program as a quasi-natural experiment,this study employs a difference-in-differences approach to examine the causal effect of supply chain innovation on urban entrepreneurial activity and explore its underlying mechanisms. The results show that the supply chain innovation and application pilot program significantly increases urban entrepreneurial activity,with the effect becoming stronger over time,indicating a dynamic and cumulative policy impact.Mechanism analyses reveal that the supply chain innovation and application pilot program promotes entre-preneurship by improving resource allocation efficiency,reducing transaction costs,and attracting venture capital.Heterogeneity analyses demonstrate that the positive effects are more pronounced in cities with higher administrative level,better business environment,and stronger innovation capacity.These findings provide causal evidence on the effectiveness of the supply chain innovation and application pilot program and offer important policy implications for promoting high-quality urban development.Moreover,they highlight the role of supply chain innovation in resha-ping urban entrepreneurial ecosystems. This study contributes to relevant literature in three aspects.First,it provides a novel research perspective.Departing from prior studies that focus primarily on firm performance or resource allocation efficiency,this paper in-vestigates how the pilot program affects urban entrepreneurial dynamism.Second,it uncovers the underlying mech-anisms.By examining resource allocation efficiency,transaction cost reduction,and venture capital attraction,the study clarifies how a macro-level supply chain policy can influence micro-level entrepreneurial behavior.Third,this study provides important policy implications.The findings highlight the role of supply chain innovation in stim-ulating urban entrepreneurial activity and enhancing development capacity.By providing causal evidence on the ef-fectiveness of the supply chain innovation and application pilot program,this study offers practical guidance for pol-icy refinement and expansion,as well as for fostering new quality productive forces and strengthening cities'innova-tion-driven growth.
