摘要
文章利用不同来源数据研究发现,中国城镇化格局变化主要表现为20世纪90年代以来"镇"人口扩张对城镇化的作用不断增强,2000年后,呈现出人口聚集"市化"和"镇化"共同驱动特征;从20世纪90年代初至今,城镇人口向东部地区集聚趋势未发生根本改变;近十几年城市群吸引人口和经济聚集能力不断增强,正成为推动城镇化的重要力量。基于城市人口规模与位序关系的研究发现,目前中国城市人口规模越大,城市人口扩张速度越快,同时城市人口分布趋向于符合齐普夫定律,表明人口在不同规模城市间的分布逐渐趋于合理,但华中地区的大城市、华南地区的中小城市发育仍显不足。文章指出,不同空间维度城镇化发展面临的问题与任务是不同的,应实施有差别的促进政策。
Based on different sources of data,this paper firstly studies the general trends of urbanization in China.The findings can be summarized as follows:(1) The rapid growth of urban population is driven by the expansion of urban population living in cities and towns,and the towns are playing more and more important role in urbanization in 2000s.(2) The trend of urban population agglomeration toward eastern region has not changed significantly yet in spite of the slowing down of population migration from middle and western areas to eastern and coastal areas.(3) The urban agglomerations have been emerging as a major driving force for urban population growth in China.This paper then discusses the issue of rational distribution of urban population in China,and finds out that the larger a city's population size is,the faster its urban population growth gets.The changing trend of urban population distribution is convergent to Zipf' law,suggesting that urban population distribution is in general becoming more rational.The development of small and middle sized cities should be encouraged in south region of China.Finally,we suggest that the government should make differentiated urbanization policies for different regions.
