一种能源消耗强度影响因素分解的新方法

A New Decomposition Method of Influential Factors on Energy Consumption Intensity

研究能源消费各影响因素对能源消费的影响程度是降低能耗节约能源的基础。能源消耗强度影响因素分解是测度能源消耗强度影响程度的一类方法,对这类方法的研究和应用有极其重要的现实意义。本文提出了一种能源消耗强度影响因素分解的新方法,该方法分别利用对数平均迪氏指数法和投入产出法的优势,在完全分解交互项的同时,充分考虑部门之间的消耗及产品结构变化等特点。通过将此方法用于中国能源强度影响因素分解的结果证明,该方法是一种行之有效的分解方法。

To study the influential degree of energy consumption influential factors impacting on energy consumption is the foundation of reducing energy consumption and saving energy. Energy consumption intensity influential factors decomposition is a class method of measuring the influential degree of energy consumption intensity influential factors impacting on energy consumption intensity. So the research and application of these methods are extremely important and practical significance. This paper presents a new approach on energy consumption intensity influential factors decomposition. This method, which takes advantage of LMDI and input- output theory, makes the alternative item decomposed completely and fully considers the character of the consumption and the structural change of product between sectors. The method is used for energy consumption intensity influential factors decomposition in China. The result shows that the method is very effective.
