Abstract:
Based on SBM and GML index,this paper overcomes the problems of Directional Distance Function and Malmquist-Luenberger index,estimating the global environmental efficiency,the total factor energy efficiency and its decomposition of the Yangtze river economic belt's logistics industry over the period of 2004 to 2013. Calculationn results show that there is environmental inefficiency widely under carbon emission constraints except Jiangsu Province; The average value of Malmquist index without considering carbon emission is 1.005 0,which is 0.009 8 and 0.010 0 higher than Malmquist-Luenberger index and GML index,indicating that the carbon emission constraint will lead to the decrease of total factor energy efficiency.; The average total factor energy efficiency of the Yangtze river economic belt's logistics industry under GML index is 0.953 6,the order of different reaches as follows:midstream > upstream > downstream,and the spatial difference of regional and provincial is declined; The technology backwards is the main cause of low level of total factor energy efficiency. In the future,the development of the Yangtze river economic belt's logistics industry should pay more attention to environmental benefits and promote the sustainable development of the Yangtze river economic belt through logistics technology improvement.
