数字产业集群政策是否推动了区域创新合作?
Has the Digital Industrial Cluster Policy Boosted Regional Innovation Cooperation?
摘要
Abstract
Promoting regional innovation cooperation is a critical measure for addressing future global competition in technology and industry and enhancing the overall efficiency of national innovation systems.From 2013 to 2017,the Ministry of Science and Technology of China launched three batches of Innovative Industrial Cluster pilots,among which 24 clusters were explicitly designated as digital industrial clusters(DIC).A comparison between pilot and non-pilot regions reveals that the number of patent cooperation applications in both regions has shown a continuous upward trend over time.However,the gap between pilot and non-pilot regions has been widening,providing preliminary evidence of the promoting effect of the DIC policy on regional innovation cooperation. This paper treats the implementation of the DIC policy as a quasi-natural experiment and employs a difference-in-differences(DID)approach to evaluate the impact of the policy on regional innovation cooperation.The empirical results indicate that the DIC policy enhances regional innovation cooperation. Then,this paper explores the underlying mechanisms based on a productive-non-productive integration framework.The analysis of productive linkages covers two dimensions:commodity markets and factor markets.In commodity markets,the DIC policy expands commodity trade to deepen the division of labor and collaboration,ultimately supporting innovation cooperation.In factor markets,the policy prioritizes rapid linkages and flexible allocation of highly mobile capital across cities,effectively supporting high-risk and highly uncertain innovation cooperation.The analysis of non-productive linkages focuses on institutional and technological linkages.For institutional linkages,the DIC policy strengthens inter-regional institutional connections through the construction of both formal and informal institutions,thereby enhancing the willingness for regional innovation cooperation.Regarding technological linkages,the DIC policy improves the efficiency of innovation resource allocation by promoting talent aggregation,knowledge spillovers,and technological complementarity,collectively strengthening the outcomes of regional innovation cooperation. In the heterogeneity analysis,this paper examines both distance heterogeneity and city-pair heterogeneity.The analysis of distance heterogeneity suggests that the DIC construction coordinates with the transportation infrastructure policy to shape new models of innovation cooperation.The analysis of city-pair heterogeneity indicates that the DIC policy helps transform established patterns of innovation distribution,break geographical constraints,and enhance core radiation,enabling greater participation of the peripheral,central,and western regions. This paper provides valuable insights for grasping the intrinsic requirements of urban development vitality,implementing the guiding principles of the Central Urban Work Conference,and achieving new accomplishments in urban development.关键词
