运用方向性距离函数,对传统的CO2排放效率测量MCPI(Malmquist CO2emission PerformanceIndex)指数进行拓展,使其能同时兼顾经济增长与减排,在充分考虑中国三大区域CO2减排技术差距的基础上,采用共同前沿Malmquist-Luenberger指数方法测算中国30个省份工业1998～2010年全要素CO2排放效率、生产率及其构成,并就三种技术基准下效率差异、低碳全要素生产率及其构成与技术创新者省份进行实证分析。结果表明:考察期内中国工业全要素CO2排放效率整体水平较低且省际差异明显,存在巨大的减排增产空间;全部省份工业的低碳全要素生产率呈递增趋势,其中,技术进步贡献大于效率改善;北京、上海和辽宁工业CO2排放技术构建了全国潜在的最优技术前沿,东部省份工业低碳技术开始分化,中、西部省份与全国潜在最优的技术差距比率以-2%和-1.3%速度逐年拉大;内蒙古和海南工业分别在2009年和2010年成为全国的低碳技术创新者。
Using the directional distance function, the traditional MCPI (Malmquist CO2emission Performance Index) is extended to take into account both economic growth and emission reduction. Based on the full consideration of the technical gaps in CO2 emission reduction in the three major regions in China, The common frontier Malmquist-Luenberger index method was used to estimate the total factor CO2 emission efficiency, productivity and composition of the industries in 30 provinces in China in 1998-2010. Based on the three technology benchmarks, the differences in efficiency, low carbon total factor productivity, its composition and technological innovation Provinces for empirical analysis. The results show that during the study period, the overall level of total factor CO2 emission efficiency in China is low and the provincial differences are obvious, and there is huge space for reducing emissions and increasing production; the low-carbon total factor productivity of industries in all provinces shows an increasing trend, of which the contribution to technological progress is greater than Efficiency; Beijing, Shanghai and Liaoning industrial CO2 emissions technology to build the country’s potential cutting-edge technology frontier, the eastern provinces began to split industrial low-carbon technology, the potential of the best provinces and central provinces and the country’s technology gap ratio of -2% and - 1.3% speed year by year; Inner Mongolia and Hainan industries in 2009 and 2010, respectively, become the country’s low-carbon technology innovators.
