基于LMDI模型的浙江省能源强度变动影响因素分析

The Factor Decomposition Analysis in the Energy Intensity of Zhejiang Province Based on LMDI Model

基于LMDI分解方法对浙江省的能源强度进行影响因素分析,研究结果表明:产业结构的变动对能源强度的变化具有积极的促进作用,但其作用相对较小;产业能源强度的变动是影响整体能源强度变化的主要因素;浙江省能源消费结构没有发生实质性的变化,仍然以传统能源为主,能源消费结构的变动对能源强度的下降起到微小的作用。

In this paper, we use logarithmic mean Divisia index （LMDI） techniques to decompose the energy intensity of Zhejiang province. And three results have been showed in this paper： （1） industrial structure can actively facilitate the change of energy intensity, but not obviously; （2） industrial energy intensity is the main factor which affects the change of the total energy intensity; （3） the energy consumption structure of Zhejiang province has not substantially changed, and remains relying on traditional energy, so it has a little influence on the decline of the energy intensity.
