基于空间相关视角的知识溢出对区域创新绩效的影响研究——以省际数据为样本

Study of Knowledge Spillover Effect on Regional Innovation Performance from the Perspective of Spatial Correlation——Based on Provincial Data Samples

本文利用2004—2013年中国30个省区的面板数据,运用引力模型测度知识溢出,在空间相关视角下构建基于不同权重矩阵的空间计量模型,实证考察知识溢出对区域创新绩效的影响.研究结果显示,十年期间各地区域创新绩效和知识溢出水平显著提高,但中西部地区与东部地区之间的差距仍然存在;在不同空间因素作用下,知识溢出均对区域创新绩效产生显著正向影响,地理距离和社会距离都是影响知识溢出效应的重要因素,其中地理距离的作用更强;地区基础设施建设水平和地区人力资本水平对区域创新绩效具有显著正向影响,而地区对外开放水平的影响显著为负.

From the perspective of spatial correlation, it analyzed the effect of knowledge spillover on regional innova- tion performance by using the panel data of 30 regions in China during 2004 to 2013, measuring the knowledge spillover with the gravity model, and constructing spatial econometric models based on different weight matrices. The results show that both regional innovation performance and knowledge spillover have improved significantly in the past ten years, but there is still a gap between the midwest regions and the east regions. Under the effect of different space fac- tors, knowledge spillover has a significantly positive impact on regional innovation performance. Both the geographic distance and social distance are the important factors that affect knowledge spillover effects, and the effect of geographic distance is stronger. The levels of regional infrastructure construction and regional human capital have significantly posi- tive effects on regional innovation performance, while the level of regional opening to the outside world has a significant- ly negative effect.
