摘要
运用空间杜宾模型(SDM)分析2008—2017年江苏省13个地级市的创新要素集聚对经济增长的空间溢出效应,结果显示:除创新人力要素集聚外,创新资本要素集聚、创新技术知识要素、对外开放水平(FDI)、创新效率均对经济增长有显著的正向空间溢出效应。从溢出效应的分解来看,创新人力要素集聚、创新技术知识集聚和FDI对经济增长的直接效应均大于间接效应,而创新资本要素集聚和创新效率则相反,即直接效应小于间接效应。
We use the latest Spatial Durbin Model(SDM)to analyze the spatial spillover effect of the agglomeration of innovative factors in 13 prefecture-level cities on economic growth in Jiangsu Province from 2008 to 2017.The results show that except for the agglomeration of innovative human factors,the agglomeration of innovative capital elements,innovative technological knowledge elements,the level of opening to the outside world(FDI),and innovation efficiency all have significant positive spatial spillover effects on economic growth.From the perspective of decomposition of spillover effects,the direct effects of innovation manpower agglomeration,innovation technology knowledge agglomeration and FDI are all greater than the indirect effects;while the indirect effects of innovation capital factor agglomeration and innovation efficiency on economic growth are greater than the direct effects.This shows that the agglomeration of innovative human factors,the accumulation of innovative technological knowledge and FDI have a significantly greater impact on the economic growth of the region than on the surrounding regions,and their radiation and spillover effects are relatively weak;while the spillover effects of innovation capital factor aggregation and innovation efficiency are relatively strong.
