摘　　要：本文通过DEA-SBM模型测算了长江经济带各省市全要素能源效率值,运用Tobit模型对长江经济带全要素能源效率进行实证分析。结果表明:长江经济带各区域之间全要素能源效率存在明显的差距,下游效率最高,其次是中游地区,上游地区效率最低;产业结构和对外开放程度对长江经济带整体能源效率起着负向影响,经济发展水平对能源效率起着正向促进影响。In this paper,deA-SBM model was used to calculate the total factor energy efficiency of provinc-es and cities in the Yangtze River Economic Belt,and Tobit model was used to conduct empirical analysis on the total factor energy efficiency of the Yangtze River Economic Belt.The results show that there is an obvious gap in total factor energy efficiency among regions of the Yangtze River Economic Belt,with the highest efficiency in the lower reaches,followed by the middle reaches and the lowest efficiency in the upper reaches.The industrial structure and the degree of opening to the outside world have a negative impact on the overall energy efficiency of the Yangtze River Economic Belt.The level of economic development has a positive influenceon energy efficiency.
