摘　　要：根据“自上而下”的方法测算了2005~2017年全国30个省级行政区交通运输业的碳排放量,结合基尼系数分析了全国及4大经济区域交通运输业碳排放的时空变化特征,并运用LMDI分解方法对碳排放影响因素及其作用进行了探讨。结果表明:研究期间全国及4大经济区域交通运输业碳排放量均呈现上升趋势,上升速度总体有所减缓;全国交通运输业碳排放整体表现为“东高西低”的空间分布状态,虽然空间分布的均衡程度稍有增加,却显著低于各经济区域的均衡程度;经济发展水平、能耗强度、行业比重、人口密度、碳排放强度和能源结构对全国交通运输业碳排放的累积影响依次递减,但是各项因素对4大经济区域交通运输业碳排放的影响作用存在差异。According to the“top to down”method,the carbon emissions of the transportation industry in 30 Chinese provincial-level administrative regions from 2005 to 2017 were calculated.Considering the Gini coefficient,the spatiotemporal change characteristics of the carbon emissions in the transportation industry in China and the four main economic regions were analyzed.The influencing factors and their impacts on the carbon emissions were investigated by the LMDI decomposition method.The results indicated that the carbon emissions of the transportation industry in China and the four main economic regions all had an upward trend during the study period,but their growth indicated a slow trend.The carbon emissions in China had presented a spatial distribution of“higher in the east and lower in the west”.Although the difference of the spatial distribution in China had slightly decreased,the difference was still higher than that of every economic region.The cumulative impact on carbon emission of the transportation industry in China,decreased in sequence of the economic development level,the energy consumption intensity,the industry proportion,the population density,the carbon emission intensity and the energy structure.However,these factors had different impacts on the carbon emissions in the transportation industry in the four main economic regions.
