交通基础设施、空间溢出对城市化进程的影响——基于省级面板数据的分析

Influence on urbanization by traffic infrastructure and spatial spillover:based on the provincial panel data

运用变量GMM方法对交通基础设施和城市化水平之间的关系进行了实证检验。结果发现,交通基础设施对城市化进程产生了显著的正向影响效应;交通基础设施对城市化进程的空间溢出效应也非常显著。如果不考虑空间溢出效应,会高估交通基础设施对城市化进程的影响,并会对政策制定产生一定的影响。

Based on the provincial -level panel data from 2003 - 2013, this essay analyses the relationship between transportation infrastructure and urbanization in China by intro- ducing different economic types of spatial - weight matrixes into the model. The results show that transportation infrastructure has very clear positive effects on urbanization and its spatial spillover effects is also very clear, its role in urbanization will be overesti- mated and influence policy making if these are neglected.
