[Abstract]:The grade structure of urban scale reflects the basic characteristics of urban development and is the basic work of urban system planning in China. The traditional research mostly uses the non-agricultural population data of the registered residence area, neglects the population flow, and has the statistical deviation. The statistical caliber of urban population in census data is close to the concept of urban entity, which should be the main index to judge the scale of urban population in the future. Based on the urban population data of the fifth and sixth census after the correction of statistical caliber, this paper analyzes the evolution law of urban scale grade structure and spatial distribution in China from 2000 to 2010 by using concentration and contribution rate. The results show that the population scale of large, medium and small cities is not harmonious, the number of big cities is small, but the scale proportion is large, the growth rate is fast, the growth contribution rate is high, the number of small and medium-sized cities is numerous, but the scale proportion is small, the growth rate is relatively slow, and the contribution rate is relatively low. Improving the capacity of population absorption in small and medium-sized cities should be an important direction of urbanization in the future. The city scale grade change is active, the promotion, the city construction follow-up and the reduced city population contraction question should be paid attention to; There are obvious spatial differences in urban scale grade structure on the scale of provinces, and the speed of urban scale upgrading in eastern provinces is obviously higher than that in central and western provinces. Urban policy formulation should take into account the characteristics of urban scale structure of different types of provinces.
