摘要
建筑业作为传统的高碳排、高耗能行业,在"双碳目标"的大背景下,其碳排放问题已成为相关研究的重点.采用排放系数法和三阶段 SBM 模型分别测度了陕西省 2013-2022 年的建筑业碳排放量和碳排放效率.结果表明:陕西省各地区建筑业碳排放量呈现陕北＞关中＞陕南的"北高南低"分布格局.第三阶段效率值结果显示陕西省整体碳排放水平不高,剔除环境变量和随机误差前后的效率值结果对比反映出外部环境确实对效率值存在较大影响.但这种影响在逐步减小,同时,各市效率值存在明显的地区差异,且这种地区差异亦有逐年缩小的趋势.
Abstract
The construction industry,known for its high carbon intensity and energy consumption,has come under increased scrutiny in the context of the"dual-carbon target."This paper applied the emission factor method and the three-stage SBM(Slacks-Based Measure)model to evaluate the carbon emissions and carbon emission efficiency of the construction industry in Shaanxi Province from 2013 to 2022.The findings reveal a spatial pattern of carbon emissions,with higher emissions in northern Shaanxi,followed by central Guanzhong,and the lowest in southern Shaanxi.The third-stage efficiency results indicate that the overall carbon emission efficiency in Shaanxi Province is relatively low.A comparison of efficiency values before and after adjusting for environmental variables and random errors underscores the significant impact of external factors,although this influence is gradually diminishing.Additionally,the analysis highlights pronounced regional disparities in efficiency across cities,with a trend toward narrowing regional differences over time.
