摘　　要：研究城市规模分布,有益于正确认识现有的城市数量和规模,为城市发展政策的制定提供理论依据。以市辖区年末总人口为指标计算,2008年我国城市规模分布的帕累托系数为1.2169,基本符合位序—规模法则;而以市辖区非农业人口为指标计算的城市规模分布的帕累托系数为1.0061,城市规模分布的均匀程度降低。除了极少数例外,经济发展水平较高的省区城市规模分布的帕累托系数相对较高,而经济发展落后的省区相对较低;与省区层面比较,国家层面的城市规模分布更均匀。The research on urban size distribution is beneficial to correctly recognize current city number and size and provides theoretical basis for making urban development policies.Taking total number of population at the end of a year in the area administered by a city as calculation index,this paper indicates that the Pareto Coefficient of China＇s city size distribution is 1.2169 in 2008,which is fit for rank-size law,however,Pareto Coefficient of China＇s city size distribution is 1.0061 by taking non-agricultural population in the area administered by a city as calculation index,which shows that the homogeneous degree of city size distribution decreases.Except very few situations,Pareto Coefficient of city size distribution of the provinces and municipalities with higher economic development level is relatively higher but is lower in the provinces and municipality with lower economic development level.Compared with provincial and municipal level,the city size distribution at national level is more even.
