政府信息透明与绿色全要素生产率的空间效应研究

Research on the Spatial Effect of Government Information Transparency and Green Total Factor Productivity

基于DEA-Malmquist指数测算省级区域绿色全要素生产率,运用莫兰指数定量分析其时空演化规律及其空间关联,借助信息透明度指数建立空间杜宾模型,实证检验信息透明度对绿色全要素生产率的空间溢出效应。结果表明在研究范围内中国绿色全要素生产率水平总体趋势稳定,存在一定波动。区域看绿色全要素生产率水平从高到低依次是东部、中部、西部,且绿色全要素生产率具有空间正相关性。信息透明和绿色全要素生产率之间存在空间非对称分布格局特征,信息透明度对绿色全要素生产率具有显著的空间溢出效应,提高信息透明度有利于中国绿色发展。最后针对中国当前绿色全要素生产率水平低、信息透明的溢出效应,提出相关政策建议以促进地区绿色、高质量发展。

Based on the DEA-Malmquist index to calculate the green total factor productivity in provincial regions,the moran index is used to quantitatively analyze the spatial and temporal evolution law and its spatial correlation,and the information transparency index is used to establish the spatial Durbin model to empirically test the spatial spillover effect of information transparency on green total factor productivity.The results show that the overall trend of green total factor productivity is stable and fluctuates.From high to low,green total factor productivity levels in the region are in the east,central and western regions,and green total factor productivity has a positive spatial correlation.There is a spatial asymmetric distribution pattern between information transparency and green total factor productivity.Information transparency has a significant spatial spillover green effect on total factor productivity,and improving information transparency is conducive to China's green development.Finally,relevant policy suggestions are put forward on the spillover effect of low green total factor productivity and transparent information in order to promote the green and high-quality development of the region.
