摘要
在介绍超效率DEA模型基础上,以反映经济发展的GDP和反映环境污染与能源消耗的相关变量为基础设计了评价生态效率的指标,并根据中国2007年的数据对各地区的生态效率进行了评价与比较,得出了全国生态效率总体偏低和地区生态效率差距较大的结论。
Based on the analysis of super-efficiency data envelopment analysis（DEA）, according to variables which reflect the economy growth and the environment pollution together with energy sources consumption, the index of evaluating eco-efficiencies were designed with the data of 2007 and the eco-efficieucies of each area in China were evaluated and compared. At last, a conclusion was drawn that the domestic total eco- efficiency was low and an obvious disparity existed in different areas.
