摘要 运用能源强度、离散系数、莫兰指数综合测度1999—2013年长江经济带工业能源效率空间差异及发展趋势,并建立面板托宾模型探索工业能源效率影响因素,分析表明:长江经济带省际工业能源效率从下游至上游存在梯度差异,空间差异由趋异向趋同转变,省际工业能源效率呈现空间集聚特征;长江经济带工业能源效率与经济发展水平、工业比重、政府影响力(财政支出比重)、电力消费比例、研发投入力度呈正相关,与能源消费比例、煤炭消费比例呈负相关,与对外开放水平的关系不明确。提高工业能源效率,长江经济带上游地区应提高研发投入在国民经济中的比重,下游地区要加快能源消费结构的优化升级,而中游地区工业能源效率受能源消费比例影响明显,提升潜力较大。 This paper synthetically measures the spatial difference and development trend of industrial energy efficiency in Yangtze River Economic Belt during 1999-2013 by using the index of energy intensity,discrete coefficient and Moran's Index and studies the influential factors of industrial energy influence factor based on panel tobit model. Analysis result shows that the spatial pattern of industrial energy efficiency emerges gradient interprovincial difference from the downstream to upstream,that the trend of spatial difference has been changed from divergence to convergence,that inter-provincial industrial energy shows spatial agglomeration character,that the industrial energy efficiency of the Yangtze River Economic Belt is positively related to economic development level,regional industrial structure,government influence,power consumption structure and RD investment but is negatively related to energy demand structure and coal consumption structure and is dimly related to economic opening level. In order to increase industrial energy efficiency,the economic belt at the up reaches of the Yangtze River must raise the proportion of RD investment to national economy,the regions at the down reaches of the Yangtze River should accelerate the optimization upgrade of energy consumption structure,however,the regions at the middle reaches of the Yangtze River have big upholding potential of industrial energy efficiency because their industrial energy efficiency is significantly affected by energy demand structure.
