| 摘 要： | 为更加全面、准确地度量影响能源强度变动的因素,在分析相关研究文献的基础上,提出包含产业结构份额、部门能源效率份额和能源结构份额的三因素几何均值能源强度分解模型,该模型不仅能够将能源消费结构对能源强度的影响从产业结构和部门效率份额中分离出来,而且克服了当数据集合中出现零值时,现有处理方法产生较大误差的缺点,提供了一种精度较高的多因素能源强度分解方法.

| Abstract: | For measuring the affecting factors of energy intensity change more comprehensively and accurately,this paper proposes a decomposition model containing industrial structure share,sectoral energy efficiency share and energy consumption structure share and chooses the geometric mean as the weight coefficient of the decomposition model based on much literature of decomposition analysis.The model successfully separates the energy structure share from the economic structure share and energy intensity share,overc... |
