摘　　要：文章基于2010-2019年中国省际面板数据,运用超效率SBM模型与GML指数,对中国30个省份公路运输碳排放效率进行测度和分析,实证结果表明:2019年中国公路运输的碳排放综合效率整体水平偏低,综合效率存在地区差异,中部>东部>东北>西部;2010-2019年中国的公路运输碳排放全要素生产率整体呈上升趋势,技术进步变化的降低是阻碍全要素生产率上升的关键因素。Based on the panel data of China's provinces from 2010 to 2019,the carbon emission efficiency of road transportation in 30 provinces and cities was measured and analyzed by using super-efficiency SBM model and GML index.The empirical results show that the overall carbon emission efficiency of road transportation in 2019 is low,and there are regional differences in the comprehensive efficiency,central>east>northeast>west.From 2010 to 2019,China's total factor productivity of road transport carbon emission showed an overall upward trend,and the decrease of technological progress was the key factor hindering the increase of total factor productivity.

关 键 词：公路运输碳排放效率 超效率SBM模型 GML指数 全要素生产率
