摘要
根据2004年—2014年的面板数据,运用DEA-CCR模型与DEA-SBM模型测度了长江经济带11个省市的经济效率与环境效率,并利用Tobit模型对影响环境效率的因素进行了分析。结果表明:非期望产出的引入降低了效率水平,少数省份对环境变量的引入较为敏感;2004年—2012年环境效率呈下降趋势,2012年之后略有上升;环境效率由下游到中游到上游依次递减,上游、下游各省市间环境效率差异大,中游各省之间环境效率差异较小。实际人均GDP、能源结构、地区因素与环境效率呈现显著正相关关系;环境规制、产业结构、技术进步呈现显著负相关关系;实际利用外商投资对环境效率无显著影响。
According to the panel data from2004to2014,the economic efficiency and the environmental efficiency of11provinces of Yangtze River economic belt are measured by DEA-CCR model and DEA-SBM model,and Tobit model is adapted to analyze the factors which affect the environmental efficiency.The results show that:the introduction of the undesirable output has reduced the efficiency level,a few provinces are more sensitive to the introduction of environmental variables;the environmental efficiency is declining from2004to2012,with a slight increase after2012;environmental efficiency decreases from downstream to midstream to upstream,the environmental efficiency differences between the upstream and downstream provinces is large,and the environmental efficiency differences between the provinces in the midstream is small.Actual GDP per capita,energy structure and regional factors have a significantly positive impact on environmental efficiency;environmental regulation,industrial structure and technological progress have a negative impact on environmental efficiency;the actual use of foreign investment has no significantly impact on environmental efficiency.
