摘要
构建了一个基于经济规模、经济结构、能源强度、能源结构和碳排放系数的恒等式。采用对数平均的Divisia(LMDI)方法对西部地区1995—2009年碳排放从产业层面和地区层面进行定量分解。结果表明:经济规模的高速增长是导致西部地区碳排放持续增加的主要因素;经济结构的调整或变化对减少碳排放的潜力尚未显现;能源强度即能源利用效率的提高是有效抑制碳排放减少的关键因素;能源结构的优化是控制碳排放增加的潜在因素。最后,提出西部地区发展低碳经济的建议。
This paper builds an identity based upon economic scale,economic structure,energy intensity,energy structure and carbon emission factor,applies Logarithmic Mean Divisia Index（LMDI） to quantitatively decompose western region＇s carbon emission from 1995 to 2009 at industrial and regional levels,with results showing that rapid growth of economic scale is the main factor causing continuous increasing of western region＇s carbon emission;the potential of economic restructuring or changing have not appeared yet;energy intensity or increase of energy efficiency is the key factor in reducing carbon emission;optimization of the energy structure is the potential factor in controlling carbon emission.This paper presents suggestions developing low-carbon economy in western China.
