摘　　要：交通运输业能耗强度、碳排放强度的上升趋势,与其他行业稳步下降的趋势相悖,使得交通运输业逐步成为节能环保的短板之一.本文在考虑CO2排放约束的前提下,构建超效率非期望Min DS模型,评价1995—2013年中国30省份交通运输业能源效率,并利用Global Malmquist-Luenberger指数,动态分析效率的变化情况.研究表明,各地区交通运输业能源效率总体呈反N型波动下降;东部、西部地区各省表现出较大差异性;中部、东北地区内各省表现出一致性,但整体水平较低;超效率非期望Min DS模型有效克服了非期望SBM模型无法完全排序和低估效率结果的问题;造成交通运输业能源效率下降的主要因素是技术效率的下降,但这一状况将在未来得到改善.With a steady decline in other industries contrary, transportation energy intensity and carbon intensity are shown an upward trend, so that transportation is becoming one of the energy saving short board.Considering CO2 emission constraint, a super- efficient undesirable Min DS model is built to evaluate the transportation energy efficiency of Chinese provinces from 1995 to 2013. The Global Malmquist-Luenberger Index is used to dynamic analysis the efficiency changes. The result shows that： the energy efficiency of Chinese transportation industry is in an overall downward trend with anti- N type; there are significant differences between provinces in eastern and western area; provinces in central and northeast region shows consistency, although the overall low level; super- efficient undesirable Min DS model effectively overcome the flaw of undesirable SBM model, and it can absolutely ranking and objectively estimate the efficiency score; the main factors that cause a decline in transportation energy efficiency is the decline of technical efficiency, but the situation will be improved in the future.
