创新溢出与区域绿色全要素互动关系研究——基于DEA-ESDA实证分析

Research on the interaction between innovation spillover and regional green total factors -- Based on DEA-ESDA empirical analysis

摘要:

采用马尔奎斯特指数、耦合协调度指数、探索性空间数据分析等方法从时间、空间两个维度对2008-2018年中国30个省市创新溢出能力及绿色全要素生产率关系、时空格局进行分析。研究结果表明：（1）从时间维度来看，我国绿色全要素生产率整体呈现上升趋势；（2）从空间维度来看，绿色全要素生产率存在显著的空间正相关性；（3）从耦合协调关系来看，当前阶段创新水平与绿色全要素生产率处于磨合耦合、基本协调阶段，表明创新水平与绿色全要素生产率之间关联性较强，但整体协调度仍具有较大的发展空间；（4）从空间回归结果来看，创新溢出与经济发展水平有利于提升绿色全要素生产率，并且主要通过技术进步影响；对外开放水平对本区域TFP增长效应不显著，对邻近区域琪消极作用，城市化进程推动本区域TFP增长、人力资本抑制本区域TFP增长，对邻近区域影响不显著。

Abstract:

Marquist index, coupling coordination index, exploratory spatial data analysis and other methods were used to analyze the relationship between innovation spillover capacity, green total factor productivity and spatial and temporal pattern of 30 provinces and cities in China from 2008 to 2018 from two dimensions of time and space. The results show that :(1) from the perspective of time dimension, the overall green total factor productivity of China presents an upward trend; (2) from the perspective of spatial dimension, green total factor productivity has a significant positive spatial correlation; (3) from the perspective of the coupling and coordination relationship, the innovation level and green total factor productivity in the current stage are in the running-in coupling and basic coordination stage, indicating that there is a strong correlation between innovation level and green total factor productivity, but the overall coordination degree still has a large space for development; (4) from the spatial regression results, innovation spillover and economic development level are conducive to the improvement of green total factor productivity, and are mainly influenced by technological progress; The level of opening to the outside world has no significant effect on the growth of TFP in this region, but has a negative effect on the neighboring regions. The urbanization process promotes the growth of TFP in this region, and human capital inhibits the growth of TFP in this region, but has no significant effect on the neighboring regions.
