With the rapid development of china’s economy, the environment of china faces some prominent questions, industrial pollution, water pollution, serious smog and other problems continue get worse, therefore, it’s very significant to analyse China’s regional environmental efficiency. This paper mainly measure china’s regional environmental efficiency by SBM model with undesirable outputs, and according to the calculation results, we find that the overall average level of china’s environment efficiency is low, and the gap between different provinces is large. Finally, this article gives some policy proposal about how to increase china’s environmental efficiency and reduce pollution emission.
