【摘要】：城市规模等级结构反映了城市发育的基本特征,是全国城镇体系规划编制的基础工作。传统研究多采用户籍城区非农业人口数据,忽视人口流动,存在统计偏差。普查数据中城区人口的统计口径接近城市实体概念,应成为今后判断城市人口规模的主要指标。基于统计口径校正后的第五次、第六次人口普查城区人口数据,运用集中度和贡献率分析了2000-2010年我国城市规模等级结构和空间分布的演变规律。研究表明:大中小城市人口规模变化不协调,大城市数量少,但规模比重大、增速快、增长贡献率高,中小城市数量众多,但规模比重小、增速相对缓慢、贡献率较低,提高中小城市的人口吸纳能力应当成为今后城市化发展的重要方向;城市规模等级变化活跃,晋级、晋档城市的城市建设跟进和降档城市的人口收缩问题应当得到关注;分省尺度下城市规模等级结构存在明显的空间差异,东部省份城市规模提升速度明显高于中西部省份,城市政策制定应考虑不同类型省份的城市规模结构特点。
[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.
