Abstract：Based on the method of IPCC list, this paper estimates the CO2 emissions of Chinese circulation industry during the period of 2000~2012. Using the method of LMDI, this paper analyzes the factors that influence the changes of CO2 emissions in the circulation industry. This paper constructs a circulation's decoupling index model based on the DPSIR framework to measure the decoupling effect of the CO2 emissions in the circulation industry. The results indicated that: during the period of 2000~2012, the CO2 emissions of Chinese circulation industry increased significantly, and the cumulative total of CO2 emissions was 6.9248237billion tons; the industrial scale effect mainly led to the increment in CO2 emissions, which amounted to 674.3572million tons. The energy intensity effect mainly led to the reduction of CO2 emissions, which amounted to 123.5867million tons. The energy structure and the emission factors have limited effect on the changes of CO2 emissions, which increased the CO2 emissions by 5.1989million tons and reduced the CO2 emissions by 25.9094million tons. The decoupling status of CO2 emissions in the circulation industry shows phasic variation, going through the process of "weak decoupling-negative decoupling-weak decoupling-negative decoupling", The variation tendency of the decoupling index value was like the shape of " ". Energy intensity is the key factor that determines the decoupling status of CO2 emissions, however, as the reduction of energy intensity become smaller and smaller, it will need to adjust the energy structure and reduce the effect of the emission factor to realize the decoupling of CO2 emissions in the circulation industry.
