Abstract: Energy saving and emission reduction are increasingly important. This paper studies a two-stage network based on the DEA-SBM model to study the two aspects. This study evaluates their efficiency, including benchmarks for improvement, of 27 regions in China from 2009 to 2013. First, the efficiency of each DMU in each stage can be obtained by the proposed model. Second, by combining the two stages, the integrated efficiency of each region can be calculated. The regions are also grouped geographically. The empirical results show that: (i)Beijing and Tianjin are the best in terms of energy system, while Gansu and Ningxia perform best in terms of environment system. (ii)From the perspective of geographical area in China, the eastern area are the best for stage one, while the western area is the best for stage two. (iii)In terms of integrated efficiency, the western area performs worst.
