中国城市规模分布及原因分析

对中国城市规模分布的帕累托指数进行计算,在选取的27个省区中有4个省区帕累托指数显著大于1。全国各省区帕累托指数的平均值为0.9337,说明中国的城市规模分布比较分散。随后,将全国27个省区按区域分为东部地区、中部地区、西部地区,应用逐步回归方法对各个地区分别进行分析。结果发现,不同的地区,与城市规模分布关系显著的因素并不完全相同。

A Revisit of the Size Distribution of Cities: The Case of China

This paper uses urban population data of China to test the validity of Zipf's law for cities in China and to identify the factors that affect the city size distribution. Each province has a Pareto exponent which indicates its city size distribution characteristics. China has a mean Pareto exponent equal to 0.9337, which means the size distribution of cities in China is not very even. This paper divides China into three regions, the east, the middle and the west. Each region uses stepwise regression with the Pareto exponent as the dependent variable. The result indicates that the city size distribution in different regions have different determining factors.
