由于中国工业行业属于能源密集型行业，提高这些行业的能源利用效率、促进节能，对于中国经济的进一步可持续发展具有重要意义。本文采用元前沿数据包络分析（DEA）方法，从技术差距、管理水平和规模三个角度分析了2000-2014年中国省级工业部门的全要素能源效率和节能潜力。研究结果表明：（1）在技术进步的推动下，样本期内能源效率大幅提升，但区域间技术差距扩大和规模效率下降是两个显着障碍； （2）目前我国工业部门能源效率仍然极低，表明能源效率提升和节能潜力巨大； （3）中国工业部门能源效率低下的根源和节能潜力呈现出明显的空间特征。据此，确定东部大部分省份应着力提升规模和管理效率，而中西部省份则应着眼于缩小地区技术差距、提高管理效率、优化产业规模三个方面。 (C) 2017 Elsevier Ltd. 保留所有权利。
Because industrial sectors in China are energy-intensive, improving energy efficiency and promoting energy savings in these sectors are of great importance for the further sustainable development of China's economy. Using a proposed meta-frontier data envelopment analysis (DEA), this paper analyzes the total-factor energy efficiency and energy savings potential in China's provincial industrial sectors for the years 2000-2014 from three perspectives, namely, the technology gap, management, and scale. The results indicate that (1) driven by technological progress, energy efficiency during the sample period was greatly improved, though the expansion of technology gaps between regions and the decline in scale efficiency represented two significant handicaps; (2) the current energy efficiency in China's industrial sectors remains extremely low, indicating that there is considerable potential for energy efficiency improvement and energy savings; and (3) the sources of energy inefficiency and energy savings potential in China's industrial sectors exhibit spatially distinct characteristics. Accordingly, it is determined that most of China's eastern provinces should focus on improving scale and management efficiency, whereas most of its central and western provinces should concentrate on three factors: narrowing the regional technology gap, improving management efficiency, and optimizing the industrial scale.
