摘要
利用数据包络分析(DEA)模型对中国大陆31个省市区的环境效率进行总体分析与评价,并利用Tobit回归模型分析环境效率的影响因素.结果表明,我国区域环境效率总体水平比较低,但环境效率正逐年好转.根据经济与环境的协调程度可以将全国划分为生态平衡区、优化发展区和集约发展区3类环境-经济功能区.人均GDP、产业结构、城市化率、生产技术水平等都是影响环境效率的重要因素,其中人均GDP、第三产业比重与环境效率呈显著正相关,城市化率和单位GDP能耗与环境效率呈弱负相关.
Environmental efficiencies of 31 provinces and their changes in China were evaluated with data envelopment analysis (DEA). Tobit regression model was also introduced to analyze the factors influencing the efficiency in the second stage. Environmental efficiencies in China were not optimistic,but had a significant progress from 2003 to 2007. Secondly,all provinces in China could be divided into ecological balance region,optimized development region and intensive development region,in terms of the coordination degree between environment and economy. Furthermore,there were significant positive relationship between GDP per capita,tertiary industry proportion and environmental efficiency but negative relationship (not very significant) between urbanization rate,energy intensity per GDP and environmental efficiency.
