基于满意度BLP-DEA的区域可持续发展系统效率评价研究

Study on Efficiency Evaluation of Regional Sustainable Development System Based on BLP-DEA and Satisfaction Degree

为了实现生态环境保护与社会经济发展的动态平衡,在对环境造成的损害最少的情况下同时获得最大的社会经济效益,是实现可持续发展的紧迫和关键问题。本文以生态子系统为上层(Leader)、经济-社会子系统为下层(Follower),构建考虑可持续发展的评价系统。通过引入公共权重、区间效率和满意度,构建基于max-min满意度的双层规划数据包络模型(BLP-DEA),并将其应用于中国省际可持续发展系统的效率评价与满意度研究。结果表明:(1)相比于BLP-DEA模型,本文构建的基于满意度BLP-DEA模型是一种令大多数决策单元能够接受自身效率值结果的评价方法,因此导致中国整体经济-社会子系统效率值相较于生态子系统效率值偏低。(2)在满足全局可持续发展系统满意度最大化的前提下,各地区的效率值体现出显著的地域性特征,其中生态子系统效率值以西部地区最优,经济-社会子系统效率值以东部地区最优,可持续发展系统综合效率值以东部地区最优。

In order to achieve a dynamic balance between ecological environmental protection and economic development,and to obtain the greatest socio-economic benefits at the same time with the least damage to the environment,it is an urgent and key issue to achieve sustainable development.The ecological subsystem is taken as the upper layer(leader)and the economic and social subsystem are taken as the lower layer(follower),and a two-level planning ecological economic and social composite system evaluation system that considers sustainable development is constructed.By introducing public weights,interval efficiency and satisfaction,a bi-level programming-data envelopment analysis(BLP-DEA)model based on max-min satisfaction is constructed.The research method is applied to the efficiency assessment and satisfaction research of China’s regional sustainable development system from 2008 to 2017.The results show that:(1)Compared with the ordinary BLP-DEA model,the BLP-DEA model based on satisfaction constructed in this paper is an evaluation method that allows most decision-making units to accept the results of their own efficiency values.In the results,the lower-level system(economic-social sub-system System)efficiency value is generally limited to the efficiency value of the upper system(ecosystem).(2)Under the premise of satisfying the maximum satisfaction of the sustainable development system,the efficiency value of each region reflects the distinct regional characteristics.Among the comparison of ecological subsystem efficiency values,the western region has the highest efficiency value;among the economic-social subsystem efficiency values,the eastern region has the highest efficiency value;among the comprehensive efficiency values of the sustainable development system,the eastern region has the highest efficiency value.
