Abstract: 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.
