长江经济带交通碳排放空间溢出效应研究——基于空间杜宾模型分析

Study on Spatial Spillover Effect of Transportation Carbon Emissions in The Yangtze River Economic Belt-Analysis Based on Spatial Doberman Model

运用长江经济带面板数据,以空间杜宾模型实证分析长江经济带交通碳排放的空间溢出效应。机动车总保有量(私家车和载货汽车保有量)对区域碳排放产生正效应,公共交通对区域碳排放产生负效应。机动车总保有量和私家车保有量的空间溢出效应为正,公共交通和载货汽车保有量的空间溢出效应为负。能源效率对长江上游地区碳排放影响较为显著,载货汽车保有量对长江中游地区碳排放影响较为明显,公共交通保有量对长江下游地区碳排放影响较为突出。

Based on the panel data of the Yangtze River Economic Belt,this paper empirically analyzes the spatial spillover effect of transportation carbon emissions in the Yangtze River Economic Belt by using the spatial Durbin model.The results show that the total number of motor vehicles,the number of private cars and trucks have positive effects on carbon emissions in this region,while public transportation has negative effects on carbon emissions in this region.The spatial spillover effects of total vehicle ownership and private car ownership are positive,while the spatial spillover effects of public transportation and truck ownership are negative.Energy efficiency has a significant impact on carbon emissions in the upper reaches of the Yangtze River,truck ownership has a significant impact on carbon emissions in the middle reaches of the Yangtze River,and public transport ownership has a significant impact on carbon emissions in the lower reaches of the Yangtze River.
