摘　　要：针对2000—2014年我国建筑业构建了碳排放强度测算模型,并基于对数平均迪式指数分解法(LMDI)对碳排放强度的影响因素从能源碳排放强度效应、能源结构效应、能源强度效应以及间接碳排放强度效应4方面进行了分解分析,结果显示:2000—2014年我国建筑业碳排放强度出现了两次波动,但总体呈下降趋势,间接碳排放强度效应对碳排放强度变化起主要作用,是阻碍建筑业碳排放强度下降的主要因素,能源结构效应与能源强度效应对其贡献较小,二者在碳排放强度上升阶段对其变化起抑制作用,在碳排放强度下降阶段对其变化起促进作用。In this paper,the carbon emission intensity of China＇s construction industry from 2000 to 2014 was measured.Then based on the theory and method of log mean decompostion index（LMDI）,the influencing factors of carbon emission intensity was analyzed from four respects： Emission intensity effect,energy structure effect,energy intensity effect and indirect carbon emission intensity effect.The results showed that from 2000 to 2014,the intensity of carbon emissions in China＇s construction industry fluctuated twice,and the overall trend was declining.Besides,effect from indirect carbon emission intensity was the main factor affecting carbon intensity in the field when compared with the effects from energy structure and energy intensity.Both energy structure effect and energy intensity effect played great roles,in which they would inhibit change of carbon intensity in the rise stage of carbon emission intensity and promote it when in the decrease stage of carbon emission intensity.
