中国主要城市绿色全要素生产率增长差异及空间溢出---基于方向性距离函数的实证分析

Green TFP growth difference of China

摘要:

本文使用了SBM方向性距离函数和Malmquist-Luenberger指数,测算并分解了中国主要城市的绿色全要素生产率(TFP),并运用空间杜宾模型研究了中国主要城市绿色TFP的空间溢出效应。本文研究认为：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；中国主要城市的绿色TFP显示出较大的地区差异,但是存在空间溢出；其中研发投入对绿色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。人力资本对于绿色TFP的增长并不表现出明显的空间溢出效应。

Abstract:

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. Regardless of the resources and environment factors will overestimate the urban TFP, thus make more optimistic judgment to our country economic growth quality. Green TFP shows that large regional differences in China, but there"s a space to overflow. R D not only has spatial spillover effect on green TFP growth, but also have local promotion effect. The spillover effect from human capital to Green TFP is insignificant.
