This paper uses the SBM-DDF model to measure the green inefficiency of all kinds of industries in Anhui Province under the constraint of carbon emissions from 2006 to 2014.The results show that whether from the perspective of the overall industries in Anhui Province or from the perspective of separate industry groups,the sources of the green inefticiency are mainly from insufficient industrial output,followed by excessive emissions of CO2.The green inefficiency values of each group(from big to small)are sized down by high-emission industries,medium-emission industries and low-emission industries respectively.During the period of research,the effect of the emission reduction in high-emission industries was not significant,and the potential of reducing the green inefficiency in the medium-emission and low-emission industries by increasing the output was not large.
