中国地级城市规模分布与集聚效应实证研究

Empirical study on the size distribution and agglomeration effects of China's regional cities

将中国划分为东部和中西部两个区域,利用中国地级城市数据,检验两个区域的城市规模分布和集聚效应的特点。研究发现,中国城市分布符合齐普夫定律,城市规模分布相对过于均匀,存在进一步集聚的空间和必要性。中国不同地区存在不同的城市规模集聚效应,东部地区的提升空间不大,未来的发展依赖于城市产业结构的调整和升级;中西部地区的利用空间较大,可通过引入具有比较优势的产业来扩大城市规模,获取城市集聚效应,从而促进城市的发展。

This article tests urban size distributions and agglomeration effects of the eastern regions and the central and western regions in China with the data of prefecture - level cit- ies. The results show that： City distributions comply with the Zip＇ s Law in China. Chinese city distributions are too uniform, and there is space and need for further combined. There are dif- ferent urban combined effects in different regions. The eastern regions with little space to develop depend on adjustment and upgrading of the industrial structure in the future. The central and western regions with larger space achieve urban combined effects to promote urban development by the introduction of the industries with comparative advantage.
