摘要
建筑业是碳排放的主要来源之一,进行江西省建筑业碳排放影响因素分析对实现江西省建筑业绿色低碳转型具有重要意义.在测算 2004-2019年江西省建筑业碳排放的基础上,采用对数平均迪式指数分解法(Logarithmic Mean Divisia Index,LMDI)将江西省建筑业碳排放增量进行分解,分析能源结构强度、能源消费强度、间接碳排放强度及建筑业经济规模对碳排放变化的贡献量和贡献率,探讨各因素对碳排放趋势的影响.结果显示:2004-2019年,江西建筑业碳排放量总体呈上升趋势.驱动因素中,建筑业经济规模效应和能源消费强度效应分别是促进和抑制江西省建筑业碳排放增长的主要因素.而能源结构强度效应、间接碳排放强度效应对碳排放也呈促进作用,但影响程度比建筑业经济规模效应低.基于实证结论,为推动江西省建筑业低碳发展提出相关建议.
Abstract
The construction industry stands out as a significant contributo carbon emission.Analyzing influencing factors of carbon emission in the construction industry in Jiangxi Province holds paramount significance to realize the green and low-carbon transformation in the region.By calculating the carbon emissions of the construction industry in Jiangxi Province from 2004 to 2019,Logarithmic Mean Divisia Index(LMDI)is applied to dissect the increment of carbon emissions within the area.The analysis delves into the factors accounting for the contribution amount and rate,including energy structure intensity,energy consumption intensity,indirect carbon emission intensity and construction industry economic scale to the variations in carbon emission.The influene of each factor on the trend of carbon emission was also discussed.The results show a consistent growing trend in the carbon emissions of the construction industry in Jiangxi Province from 2004 to 2019.Among the driving factors,the economic scale and energy consumption intensity of the construction industry emerge as the primary factors that promote and inhibit the growth of carbon emissions of the construction industry in Jiangxi Province,respectively.While energy structure intensity and indirect carbon emission intensity also play a row in boosting carbon emissions,their impact degree is comparatively lower than that of the economic scale of the construction industry.Based on the empirical conclusions,some relevant suggestions are proposed to promote the low-carbon development of the construction industry in Jiangxi Province.
