江西省绿色经济效率及区域差异研究——基于非期望产出SBM模型

Study on the Green Economic Efficiency and Its Regional Differences in Jiangxi province——Based on Undesirable Output SBM Model

提升绿色经济效率是高质量发展的要求,也是达成经济和环境双重效益的重要路径。通过引入能源消耗和污染排放等数据构建非期望产出SBM模型,分析江西省绿色经济效率及区域差异。研究结果显示,无论是静态水平分析还是动态分析,均表明江西省总体上具有绿色经济效率,但省内区域差异明显。根据纯技术效率值和规模效率值将区域差异分成四种类别,分别讨论了每种类别的改进或发展措施。

Improving the green economic efficiency is the requirement of high-quality development,and an important path to reach the both economic and environmental benefits.This paper constructs the undesirable output SBM model by incorporating the data of energy consumption and pollution emission,and analyzes the green economic efficiency and its regional differences in Jiangxi province.The results show that both the stationary and dynamic levels analysis indicated that Jiangxi province has green economic efficiency on the whole,but there are obvious regional differences in Jiangxi province.This paper further divides the regional differences into four categories according to the pure technical efficiency value and scale efficiency value,and discusses the improvement or development measures of each category respectively.
