中文摘要：

基于1995 ～2010年中国28省市的统计数据,运用空间计量经济学方法分析了中国城市规模扩张过程中交通碳排放所隐藏在时空格局和演变趋势背后的内在机制；采用经济增长收敛理论,分析了中国28个省市的交通碳排放量的分布特征和收敛性.研究表明：①中国交通碳排放在空间上具有集聚倾向,各省市的平均自发交通碳排放水平相同,但各省市的自发交通碳排放水平存在较大差异,沿海发达地区交通碳排放量较高,西部地区较低；②其间,中国交通碳排放虽然不存在一致σ收敛,但存在16阶段（年）σ收敛和β绝对收敛性,β绝对收敛速度约为8.3％；③在长期均衡状态下,人均GDP、城市建成区面积、车均能耗对交通碳排放的弹性分别约为0.93、0.34、0.65.基于研究,提出了中国交通碳减排的政策取向.

英文摘要：

Based on 1995 -2010 statistical data of China＇s 28 provinces, this paper adopts the method of spatial econometrics to analysis the inherent mechanism of transport carbon emissions behind the spatio-temporal pattern and the evolution trend in China City Size rapid expansion process, using the convergence theory of economic growth to analysis the distribution characteristics and the convergence of the transport carbon emissions of China＇s 28 provinces. The results are as follow： ①There is a spatial agglomeration tendency on China＇s transport carbon emissions, the same average spontaneous level of transport carbon emissions in the provinces, but there is a big difference in levels of spontaneous carbon emissions, high transport carbon emissions for the developed coastal areas, and the western regions is relatively low. ②From 1995 to 2010,China＇s transport carbon emissions there is no uniform σ convergence, but there are 16 stages （ years ） α convergence and absolute β convergence, and the βconvergence speed is about 8.3%. ③he long- term equilibrium elasticity of the per capita GDP, urban built-up area and per car energy consumption on transport carbon emission are about 0. 93, 0. 34, 0.65. Based on the research, China＇s transport carbon emission reduction policy orientation is put forward.
