本文基于非径向的SBM模型测度了中国省区二氧化碳排放效率，并分析了Luenberger生产率指标及分解，从技术进步效应、效率追赶及“创新者”区域等角度探索中国省区二氧化碳排放效率。主要结论有：2000-2011年间的全国二氧化碳平均排放效率仅为54.9%，效率偏低，相对于效率前沿面存在较大的改善空间；东部、中部和西部三大区域的二氧化碳排放效率发展是不均衡的，东部二氧化碳排放效率显著高于中、西部；全国二氧化碳生产率MLPI指标平均增长率为0.62%，增长率较低，生产率增长的主要源泉是技术进步而非效率变化。

This paper measure the efficiency of carbon dioxide emissions in China based on the traditional DEA and SBM Model. Then calculates productivity index of the carbon emissions and its decomposition, and analysis the effect of technology progress, efficiency change and the "innovators" region. The study obtains the main conclusions: SBM model has advantages in the number of effective units and efficiency division. The average carbon dioxide emissions of the country is only 54.9% during the period of 2000-2011, there is still large room to improve relatively to the frontier. The carbon emission efficiency of the East, Central and West regional are imbalance, the efficiency in East is significantly higher than that in Central and West. The average growth rate of MLPI in China is only 0.62%.The main source of productivity growth is the technological progress rather than the change of efficiency.
