Abstract:Based on the analysis of design proposals and survey data from seven Chinese pilot carbon emission trading systems (ETS) and simulation ETS of 19 regions, apply the C2GS2 model as the basic tools to build the data envelope analysis method (DEA) to evaluate the management efficiency of each ETS unit. The model assessment results showed that in the seven pilot ETS units, that of Beijing, Guangdong, Shenzhen and Chongqing are effective management under the DEA method, Shanghai ETS and Tianjin ETS are in the scale ascending stage, Hubei ETS is in the scale descending stage. For three non-DEA effective ETS units, their “efficient projections” on the production frontier surfaces were analyzed for proposing adjustment programs. This study suggests as follows: the coverage of ETS should be less than 50% of total regional emission; the proportion of CCER for compliance should be lowered; in-put factors of each ETS should reflect the feature of the regulated enterprises; punishment mechanism is essential and should be in accordance with violators’ bearing capacity; the emission cap of ETS should not be designed too tight, or it may damage sustainable development capability of regional economy.
