省际环境效率俱乐部收敛及动态演进分析

Analysis of Convergence of Provincial Environmental Efficiency of China and Dynamic Processes

鉴于传统收敛模型的局限性,基于PS模型对中国30个省际2005—2014年环境效率的收敛特征进行分析。研究结果表明:(1)我国环境效率整体上不存在收敛,但是存在4个收敛类型和1个发散类型,其中类型A和类型B的相对路径趋于上扬,其所包含的省际的环境效率均高于其他类型;类型C、类型D和类型E的相对路径均在1以下,其所包含的省际的环境效率均低于全国总体平均水平,而且这部分省际数量占据了全国总体数量的2/3,是拉低全国环境效率的主要因素。(2)研究期间省际环境效率呈现“两极分化”或“多极分化”的趋势。(3)进一步研究表明,经济发展、产业结构是俱乐部形成的主要因素。

In view of the limitations of the traditional convergence models,the convergence characteristics of environmental efficiency in 30 provinces in China from 2005 to 2014 are analyzed based on the PS model.The results show that there is no convergence in China’s environmental efficiency,but there are four types of convergence and one divergence type.The relative path of type A and type B tends to rise,and its intervening environmental efficiency is higher than that of other types.The average path of type C,type D and type E is below 1,and the province’s environmental efficiency is lower than the national average,and this part of the inter-provincial quantity occupies 2/3 of the national average.These are core classes with reducing the environmental efficiency.During the study,provincial environmental efficiency shows a“polarization”or“multipolar differentiation”trend by nuclear density model.Further,economic development level and industrial structure are the main influencing factors for club.
