摘　　要：要在促进社会经济发展的同时减少二氧化碳排放量,关键在于提高二氧化碳排放绩效。客观正确地评估中国各省份经济发展过程中的二氧化碳排放绩效具有重要现实意义。文章从效率的角度,界定二氧化碳排放绩效的概念,将二氧化碳排放作为非期望产出纳入全要素研究框架,探索性地利用三阶段DEA方法和线性数据转换函数法来评价中国省际区域的二氧化碳排放绩效,剔除了环境变量和随机误差对结果的影响,为真实测度二氧化碳排放绩效提供了可行的方法。结果表明,传统DEA测度的二氧化碳排放平均技术效率和纯技术效率被低估,而平均规模效率被高估;中国区域间二氧化碳排放绩效发展显著不平衡,呈现出"东>西>中"的格局,与传统的经济格局存在一定出入。China is at an important stage of modernization,industrialization and urbanization,and its growing consumption of fossil fuels is pushing China towards becoming the largest emitter of carbon dioxide globally.To improve the carbon dioxide emission performance and develop a low-carbon economy is the only way to achieve sustainable development in China.From the view of efficiency,the paper defined the concept of the carbon dioxide emissions performance and put the undesirable output into the total factors framework that included capital stock,stuff population and total energy consumption.Based on a three-stage DEA method,it excluded the impact of external environmental factors and random errors,and then evaluated objectively carbon dioxide emission performance of all provinces in China.We found that average pure technical efficiency is underestimated largely before eliminating external factors and random errors,while scale efficiency is underestimated weakly,which results in an underestimate of technical efficiency.The pure technical efficiency was always higher than the scale efficiency,reaching the optimal frontier,which means increasing inputs and enlarging scale are the most important ways to improve carbon dioxide emission performance.Eastern China was the highest and central China was lowest,which different slightly from the traditional economic situation.We conclude by discussing measures to improve China’s carbon dioxide emissions performance,such as strengthening the cooperation between regions,and adjusting respective economic structures and production models.
