本文基于能源消费强度的恒等式,采用对数平均权重Divisia分解法(Logarithmic Mean Weight Divisia Method,LMD),建立中国三大产业能源消费强度的因素分解模型,定量分析了1995年-2007年间,能源效率因素和结构因素的变化对中国能源消费强度的影响,并研究了煤、石油、电力三种能源消费强度的两因素分解贡献值比较和三大产业间效率因素和结构因素的贡献份额比较对中国能源消费强度的影响,结果表明第二产业的效率因素是影响中国能源强度变化的主要因素,煤的消费强度与中国能源的消费强度变化一致,提出了降低第二产业重点耗能产业的能源效率、技术进步和优化经济结构三大管理对策。
Based on the identity of energy consumption intensity, the Logarithmic Mean Weight Divisia Method (LMD) is used to establish the factor decomposition model of the energy consumption intensity of the three major industries in China. The quantitative analysis of the energy efficiency between 1995 and 2007 Factors and structural factors on the intensity of energy consumption in China and studied the contributions of three factors of the three energy consumption intensity of coal, oil, electricity and the comparison of the contribution of efficiency and structural factors among the three major industries. The results show that the efficiency factor of the secondary industry is the main factor that affects the change of China’s energy intensity. The consumption intensity of coal is consistent with that of China’s energy consumption. The paper proposes that reducing the energy efficiency of key energy-consuming industries in the secondary industry , Technological progress and optimizing the economic structure of the three management strategies.
