The Empirical Studies of Mar-Effect & Jac-Effect of Knowledge Spillover in HighTech Industrial Clusters in China

This paper selected 54 high-tech industrial development zones in China as the research sample.Firstly,the Mar-effect and Jac-effect of knowledge spillover were measured in high-tech industry clusters in China.The results show that the Mar-effect was greater than Jac-effect in coastal developed region clusters,and it was opposite in the western underdeveloped regions.Secondly,by constructing the knowledge spillover radius model,and setting up space weight matrix,the knowledge spatial spillover effect of the high-tech industry clusters is discussed.The results revealed that: the Mar-spillover and the Jac-spillover can well reflect respectively,the knowledge spatial spillover effect within the high-tech industry cluster and among the high-tech industry clusters.When the spillover effects of the knowledge with Mar-effect,Jac-effect by extracting,the economics development variables of high-tech industrial clusters have no longer spatial correlation.And finally,by building space fixed effect panel data model,the effects of knowledge spatial spillovers for high-tech industry clusters economic growth and technology progress are discussed.The results show that: Mar-spillover play significant positive role on economic growth,but play significant negative role on technological progress.Instead,Jac-spillover play significant negative role on economic growth,but play significant positive role on technological progress.
