摘　　要：本文基于生产理论的CO2减排效率的因素分解模型,对影响我国CO2减排效率的因素进行分解,分析能源使用和CO2排放两种技术的进步与效率对我国30个省区CO2减排效率的影响,并运用环境方向性距离函数建立以资本、劳动力和能源为投入要素,以GDP和CO2排放为产出的分别基于投入导向和产出导向的规模报酬不变的DEA模型,分别测度全国30个省区1995—2010年期间全要素CO2的减排效率。在此基础上,对我国30个省区的全要素CO2减排效率的影响因素进行实证分析。本文发现,1995—2010年间,在全国30个省区中,能源使用和碳排放的技术因素对CO2减排效率和CO2减排效率的变化率有较强的正影响,现阶段提高能源使用和碳排放的技术效率和技术水平是提升我国全要素碳减排效率的关键因素。Based on the factor decomposition model of CO2 emission reduction efficiency under production theory, this paper decomposes factors that affect China＇ s CO2 emission reduction efficiency, analyzes the effect of two kinds of technology of energy use and CO2 emission which have on China＇ s 30 provincial CO2 emission reduction efficiency, and applies the environmental directional distance function to establish the DEA model constant returns to scale input-oriented and outputoriented which takes capital, labor and energy as input elements, and GDP and CO2 emissions as output, measures the total factor CO2 emission reduction efficiencies of China＇ s 30 provinces during 1995--2010 respectively. On this basis, this paper empirically analyzes the influencing factors of total factor CO2 emission reduction efficiency of China＇ s 30 provinces. This paper finds out, during 1995--2010, the technical factors of energy use and CO2 emission reduction have a strong positive influence on the CO2 emission reduction efficiency in 30 provinces. Enhancing the technological efficiency and level of energy use and CO2 emission reduction is the key factor of promoting China＇ s total factor carbon emission reduction efficiency.
