绿色增长效率及其空间溢出——基于中国主要城市的经验分析

Green Productivity and Spatial Spillover: An Empirical Analysis Based on Major Chinese Cities

使用SBM方向性距离函数和Malmquist-Luenberger指数,测算并分解了中国66个城市的绿色全要素生产率(TFP),并运用空间杜宾模型探讨其空间溢出效应。研究认为:前沿技术进步是绿色TFP增长的主要贡献因素,而环境技术效率的改善却比较滞后;66个城市的绿色TFP显示出较大的地区差异,但是存在空间溢出;其中人力资本对绿色TFP的增长不仅具有空间溢出效应,也具有明显的本地促进效应,而R&D仅具有空间溢出效应,本地促进效应并不明显。

This paper uses SBM directional distance function and Malmquist - Luenberger index approach to measure green TFP of China＇ s major cities, and analyzes the influence factors. We apply SDM to analyze the spillover of urban green TFP and its influencing factors. The major conclusions are as follows： Green TFP growth is mainly composed the contribution of frontier technology progress, environmental technology efficiency improve relative lag. Green TFP shows that 66 city＇ s differences in China, but there＇s a space overflow effects. Human capital has both spatial and local spillover effect on green TFP growth, while R＆D only has spatial effect on green TFP and the local effect is insignificant.
