General Trends of Urbanization and Rational Distribution of Urban Population in China
Abstract: Based on different sources of data, this paper first studies the general trends of urbanization in China, and the findings can be summarized as follows: (1) the current rapid growth of urban population is equally driven by the expansion of urban population living in both towns and cities as the towns are playing more and more important role in urbanization; (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 groups are emerging as main driving forces for urban population growth in China. From a perspective of Zipf’s law, this paper then discusses the issue of rational distribution of urban population in China, and finds out that the urban size is positively correlated with urban population growth, the larger population size, the faster urban population growth. Nevertheless, the changing trend of urban population distribution is characterized with convergence to Zipf’ law, suggesting that urban population distribution is in general becoming more rational. Finally, this paper explores China’s urban population distribution by regions, and concludes that the big metropolitan cities need to be nurtured in the central region of China while the development of small and middle sized cities should be encouraged in south region of China. All of the findings in this paper might be conducive to policy making in regional planning for urbanization.
