中文摘要：

交通基础设施和信息基础设施会通过降低运输成本、优化空间布局以及重塑企业内外部网络关系等机制进一步加强城市体系各节点之间的联系,推动城市规模分布向多中心和分散化发展,最终促进城市体系网络化发展;各地区城市规模分布之间存在较强的空间相关性,相邻地区城市规模分布单中心程度和集聚程度的提高,会对本地区的城市规模分布造成＂虹吸效应＂。

英文摘要：

The study shows that ,transport and information infrastructure will strengthen the links between the nodes in urban system ,by the mechanisms of reducing transport costs, optimizing spatial layout and remodeling firms＇ internal and external network relations, and then promoting the city-size distribution towards multiple centers, decentralization and networking development finally. It is also found out that the spatial correlation between various regions of the city-size distribution shows a strong correlation. Moreover, the raise of single-center and agglomeration of city-size distribution in adjacent areas will resuh in the ＂siphon effect＂ on the local area.
