Spatial and temporal evolution characteristics and driving factors of urban traffic carbon emissions in Jiangsu Province
Based on the panel data of cities in Jiangsu Province from 2001 to 2021,combined with the IPCC carbon emission calculation scheme,the carbon emissions of urban transportation departments in Jiangsu Province were measured completely by the"bottom-up"method,and the influence mechanism and influence heterogeneity of eight factors on carbon emissions were analyzed by using the two-level LMDI addition decomposition model.The results show that the traffic carbon emission in Jiangsu Province has experienced three stages:the high-speed growth stage from 2001 to 2005,the medium-speed growth stage from 2006 to 2013,and the low-speed growth stage from 2014 to now,and the growth rate has remained stable below 10%.As for the spatial change trend,the traffic carbon emissions in Jiangsu Province are characterized by"high in the south and low in the north",and Suzhou's carbon emissions account for about 1/3 of Jiangsu Province.As for the driving factors,energy efficiency,economic level,public transport saturation,green vegetation coverage and population size are the driving factors,while industrial structure,public transport participation and land use structure are the main driving factors,among which economic level is the primary driving factor and public transport participation is the main driving factor.
