本文旨在探讨导致中国能源密集型产业能源强度下降的主要因素。将指标分解分析法和产量分解分析法相结合，完成了分解分析。总体来看，有七个因素与能源强度的下降有关，其中技术进步效应最为显著。技术效率效应在12个省份与下降正相关，在17个省份与下降负相关。资本-能源替代效应有利于20个省的下降。可再生能源替代效应是造成能源消费下降的主要原因，不同能源类别之间的替代效应可以忽略不计。从省域贡献来看，只有新疆省为负贡献。辽宁、河北和上海三省对能源强度下降的贡献最大。主要政策含义包括：加大对高耗能产业的研发投入，转变高耗能产业的集约化发展模式，逐步改革能源价格，完善高耗能产业布局。
This paper seeks to investigate the main factors causing the decline in energy intensity of China's energy intensive industries. Index Decomposition Analysis and Production Decomposition Analysis methods are combined to complete the decomposition analysis. Overall, seven factors are related to the decline in the energy intensity and technology improvement effect is the most significant factor. Technical efficiency effect is positively related to the decline in twelve provinces but negatively related in seventeen provinces. Capital-energy substitution effect is beneficial to the decline in twenty provinces. Labor-energy substitution effect undermines the decline and substitution effect among different categories of energy can be ignored. Considering provincial contribution, only Xinjiang Province has a negative contribution. Liaoning, Hebei and Shanghai provinces make the largest contributions to the decline in energy intensity. The main policy implications include enhancing investments in research and development in China's energy intensive industries; transforming the intensive development model of the energy intensive industries; gradually reforming energy price; and improving the layout of energy intensive industries.
