We used the Slacks-based Model (SBM) to calculate the environmental efficiency value of industrial cluster districts in China based on the panel data of 30 regions from 2007 to 2014, at the same time, in order to make a comparative analysis with the economic efficiency values not considering carbon emissions,
... g carbon emissions, the model presented by Banker, Charnes and Cooper (BCC) for estimating technical and scale inefficiencies in data envelopment analysis was used to calculate the environmental efficiency not considering the desirable output of carbon emissions, and we also analyzed the regional differences in China's environmental efficiency. The results showed that the environmental efficiency value of industrial cluster districts in China ranged between 0.83 and 0.94 not considering carbon emission, and it had a certain degree of reduction when considering the effect of undesirable output, maintaining values between 0.74 and 0.84, and which showed that there was much room for improving the environmental condition of the industrial cluster districts in China. Carbon emission had a great impact on the environment of China's industrial cluster, which resulted in a greater degree of efficiency loss. And it showed that the carbon emissions showed a great difference to the sensitivity degree of influence on regional environmental efficiency.
