摘　　要：数据包络分析已经被广泛应用于研究中国各省市的能源与环境效率.在以前研究文献中,模拟弱可处置性建模时,隐含的假设所有决策单元采用统一均匀的减少系数.但是在实际生产过程中,面对边际减排成本最低的决策单元,减少非期望产出,也通常会带来成本效益,而且决策者也往往更倾向于减少那些带来成本效益更低的决策单元.因此,为解决这一实际问题,引进不同决策单元的非期望产出采用非均匀比例减少的基础上,考虑非能源投入和能源投入的划分,来构建评估中国各个省市能源和环境效率的生产可能集,然后利用改善的DEA模型计算2016年中国其中30个省市的能源与环境效率.结果表明,我国不同区域,相同区域不同省市之间的能源与环境效率都存在着较大差异.Data envelope analysis has been widely used to study energy and environmental efficiency in China’s provinces.In previous research literature,when simulating weak disposability modeling,the implicit assumption is that all decision making units adopt uniform abate-ment factor.However,in the actual production process,the reduction of undesired output is often cost-effective in the face of the least marginal cost of reducing emissions,and policymakers tend to be more inclined to reduce the cost-effective places.Therefore,on the basis of overcoming the non-uniform proportional reduction of the undesired output and the desired output of different decision making units,this paper,taking into account the division of non-energy input and energy input,and constructing the production possible set to evaluate the energy and environmental efficiency of various provinces in China.Then we use the improved DEA model is used to calculate the energy and environmental efficiency of 30 provinces in China in 2016.The results show that there are large differences in energy and environmental efficiency between different regions are different provinces in China.
