基于LMDI分解的山东省城乡居民生活碳排放研究

Analysis on Carbon Emissions of Urban and Rural Residents'Lives in Shandong Province based on LMDI Method in Decomposition

山东省居民生活减排是实现低碳发展目标的关键之一。2010—2020年山东省城乡居民生活直接与间接碳排放量均呈增长趋势,城镇居民生活间接碳排放量更是农村居民的2倍之多。从消费者责任视角出发,基于LMDI模型分析各因素对山东省城乡居民生活间接碳排放的贡献度,结果表明,城镇化建设与人均消费水平提升间接产生了大量碳排放,碳排放强度降低可显著抑制间接碳排放,居民消费结构变化逐渐显现出对间接碳排放的抑制作用。

Emission reduction of residents'lives is one of the keys to achieving the goal of lowcarbon development in Shandong Province.From 2010 to 2020,the direct and indirect carbon emissions of residents in Shandong province showed an increasing trend,and the indirect carbon emissions of urban residents were more than twice that of rural residents.From the standpoint of consumer responsibility,using LMDI model analyzed the contribution of various factors for the indirect carbon emissions of urban and rural residents in Shandong Province.The results show that urbanization and the increase of per capita consumption level indirectly produced a large amount of living carbon emissions.The reduction of carbon emission intensity can significantly restrain indirect carbon emissions,and the change of household consumption structure gradually shows the inhibitory effect on indirect carbon emissions.
