Decomposition Analysis of Changes in Metropolitan Energy Consumption in China Based on the Logarithmic Mean Divisia Index

基于LMDI的中国特大城市能耗变化量的分解分析（英文）

The energy consumption of China＇s metropolitan areas has expanded from production areas to other areas such as the service area,and characteristics differ across small and medium-sized cities.Using the Logarithmic Mean Divisia Index（LMDI） decomposition method,we conducted a factor decomposition analysis on changes in energy consumption for 32 Chinese metropolises from 1995–2012 that had a resident population of at least 1 million people in 1995.On the basis of a comprehensive consideration of urban economic growth,population expansion and spatial expansion,energy consumption factors can be decomposed into five indicators： economic scale,energy consumption per unit of output value,energy consumption per capita,population density and energy space support coefficient.We valued the contribution of each factor to metropolises＇ energy consumption to determine generality and regional differences.

特大城市的能耗在全国能源系统中扮演着极其重要角色,但其能耗已从生产领域转向城市功能和自身发展方面。因此,本文利用迪氏对数指标分解法对1996-2012年间32个特大城市的能耗变化做因素分解分析,综合考虑城市经济增长、人口规模扩大和空间扩张三方面因素的基础上选取5项指标,计算其对城市能耗的贡献率,分析共性与差异,以更有针对性的开展城市能源管理和节能减排工作。
