基于LMDI模型的辽宁省交通碳排放影响因素
Influencing Factors of Transportation Carbon Emission in Liaoning Province Based on LMDI Model
摘要
Abstract
Taking the transportation industry of Liaoning Province as the research object,the energy consumption and carbon emissions of different transportation modes were calculated according to the published data of transportation from 2010 to 2021.Based on the Kaya equation,combined with the situation of Liaoning Province and specifically considering the ecological and urban construction equations,the influencing factors of carbon sink production and sales rate and ecological scale were added,and the LMDI(logarithmic mean divisia index)decomposition method was used to decompose them.The results show that energy intensity,structural effect,industrial scale,economic output,production and sales rate of carbon source and carbon sink and ecological scale have promoting effects on road traffic carbon emission in Liaoning Province.Traffic carbon emission intensity,traffic intensity and population density usually have inhibitory effects on road traffic carbon emission in Liaoning Province.关键词
