The Action of Structure and Efficiency on Chinese Energy Intensity: An Empirical Analysis Based on AWD Changes and Factors Decomposition of Chinese Energy from 1978 to 2007

摘要

An adaptive weighting divisia index method is applied to analyze the structure and efficiency quotient mix in affecting Chinese energy intensity through rearranging and reanalyzing the past 30 years' data. Based on the analysis, this paper concludes that the changes in China's energy intensity in the previous phase are mainly caused by efficiency factors, and by estimation it shall be affected by structural factors in certain period of future. Subsequently, potential direction of energy conservation in future is suggested in the context of economic evolvement of China. In addition, the upturn in energy intensity after 2000 are particularly analyzed and interpreted comprehensively.
