摘要
能源要素作为人—地关系系统的重要组成,其作用随着能源开发利用总量、能源利用结构与经济发展等随之演变。采用弹性脱钩指数和广义LMDI方法,研究了20世纪50年代以来中国能源消费与经济增长的动态关系以及能源消费增长的驱动因素。结果显示:(1)中国能源消费总量与GDP增长都呈现指数型增长曲线,且两者的增长态势表现出高度的一致性,且煤炭和石油仍然是中国能源消费的主体。(2)能源消费与经济增长之间的弹性脱钩状态表现出明显的阶段性特征,当前二者之间的关系整体表现为弱脱钩的相对乐观状态。(3)不同类型能源消费与经济增长的脱钩状态呈现一定的差异性。近年来伴随着能源消费的清洁化转型,天然气、一次电力和其他能源消费与经济增长之间呈现为拓张负脱钩或拓张连接状态。(4)影响能源消费增长的驱动因素中,能源强度是能源消费量降低的最主要因素;投资拉动是能源消费增长的主导因素,土地效应是推动能源消费增长不可忽视的重要因素,其贡献率为35.65%。产业结构效应、劳动力效应和能源结构效应对能源消费增长的整体贡献在15%左右。
As an important component of social-environmental relationship system, energy elements evolve with the total amount of energy development and utilization, energy using structure and economic growth. Based on elastic decoupling index and the generalized LMDI method, this paper studies the dynamic relationship between China＇s energy consumption and economic growth and the driving factors of energy consumption growth. Results show that：（1）Since the founding of the People＇s Republic of China, the total energy consumption and GDP growth in China present an exponential growth curve, and their growth shows a high degree of consistency. Coal and oil are still the main body of China＇s energy consumption.（2） The elastic decoupling between energy consumption and economic growth is featured by obvious periodic characteristics, and the overall relationship between the two is kept in a relatively optimistic status（the weak decoupling）.（3） The decoupling status for different types of energy consumption and economic growth show certain differences. In recent years, along with the clean transformation of energy consumption, natural gas, primary electricity and other energy consumption and economic growth are presented in a negative decoupling or extension connection status.（4） Energy intensity effect is the most important factor contributing to reducing energy consumption growth. Investment effect is the leading factor contributing to energy consumption growth, and the land effect is an important factor promoting the growth of energy consumption, with its contribution rate being 35.65%. The overall contribution of industrial structure effect, labor force effect and energy structure effect to promote energy consumption growth is around 15%.
