江西省工业绿色生产率增长及影响因素——基于动态面板数据的实证研究

Jiangxi Industrial Green Productivity Growth and Influence Factors——Based on an empirical analysis of the dynamic panel data

利用方向距离函数和Malmquist–Luenberger指数,分析了江西省地区间工业绿色生产率的增长状况,研究发现工业绿色生产率水平整体偏低,仅南昌市、九江市和新余市增长率为正值;省会南昌市表现的最突出;分解来看,技术进步是绿色生产率增长的最主要的部分,效率改善作用较小。在此基础上,利用动态面板数据的广义矩方法分析了江西省工业绿色生产率的影响因素,实证研究表明R&D投入强度、对外开放程度对地区工业绿色生产率增长有显著的促进作用。

This paper,using the directional distance function and Malmquist- Luenberger index,analyzes the industrial green productivity growth in Jiangxi,finding that the industrial Green productivity growth is low except that it is positive in Nanchang,Jiujiang and Xinyu,and that in Nanchang it is the most prominent. By decomposition,the technological progress is the main part of the green productivity growth with less efficiency improvement effect. Based on it,the paper,by using the dynamic panel GMM,analyzes the influent factors of the green productivity,showing that the input intensity of R D and the degree of opening have the prominent promoting role in the regional industrial green productivity growth.
