Abstract Environmental efficiencies of 31 provinces and their changes in China were evaluated with data envelopment analysis (DEA). Tobit regression model was also introduced to analyze the factors influencing the efficiency in the second stage. Environmental efficiencies in China were not optimistic, but had a significant progress from 2003 to 2007. Secondly, all provinces in China could be divided into ecological balance region, optimized development region and intensive development region, in terms of the coordination degree between environment and economy. Furthermore, there were significant positive relationship between GDP per capita, tertiary industry proportion and environmental efficiency but negative relationship (not very significant) between urbanization rate, energy intensity per GDP and environmental efficiency.
