The gradual advancement of carbon emissions operations is an effective market tool to achieve CO2 emission reduction targets at a lower cost. This paper sorts out the existing research results, and determines the total amount of carbon allowances, the number of carbon emission verification agencies, and the carbon market emission control coverage rate as input indicators for carbon emission operation efficiency, and carbon trading price and carbon emission trading volume as carbon emission operation efficiency indicators. According to the indicators, the DEA method is used to establish an evaluation model of carbon emission operation efficiency, and Beijing, a pilot city for carbon emission, is selected for example analysis. The results show that reducing the input of evaluation indicators such as the total amount of carbon allowances, the number of carbon emission verification agencies, and the carbon market emission control coverage rate, and increasing the output of carbon trading prices and carbon emissions trading volume evaluation indicators will make the operation efficiency of carbon emission pilot cities reach Balanced state.
