Abstract:

In the new round of urbanization, the innovation economy with human capital as the core has gradually become the engine of driving economic growth, the important function of the provincial central city as a population gathering place is increasingly prominent. The tendency of the floating population affects the reconstruction of the urban system between cities of different scales and administrative grades, the core subject of studying population change plays an important role in the process of urbanization. Therefore, this paper selects typical cities in each province as the objects, estimated by the latest data of urban population, revealing the recent development trend of China’s urbanization and the changing pattern of metropolitan regional structure. Found from it, in recent years, the development trend of China's population urbanization has gradually stabilized, and there are still significant differences in population agglomeration in different regions and cities of different scales, all kinds of municipalities directly under the central government, provincial capitals, and sub-provincial cities have outstanding performance in population agglomeration, the population attractiveness of traditional port cities, industrial cities, and provincial sub-central cities is gradually weakening. Among them, the absorption capacity of the first-tier cities is super strong, the secondary cities become important gathering places for the population, the population growth rate of the third-tier cities is slowing down, the population of the fourth-tier cities is stable, and the cities can be divided into four different combinations. They are “high/low scale” and “high/low growth”. At the same time, the growth of urban population will directly affect the economic development of urban areas, in particular, the central and central cities in the central and western regions have become more powerful and have a strong population growth, which has changed the pattern of the traditional East, Central and West regions, the provincial capital city showed four different combinations of “high/low order” and “high/low concentration”, and the provincial capitals were concentrated in two types: “high order, high concentration” and “low order, low concentration”, the pattern of differentiation is relatively obvious. With the continuous development of China's metropolis, it has gradually become a leader in the new era of innovation economy and population agglomeration. The higher the administrative level, the more obvious the advantage of resource allocation. China's metropolis has the advantage of attracting population agglomeration, thereby further enriches the urban labor market and making it more advantageous in economic development.Thereby continuously consolidating the important position of the metropolis in China's urban system. Therefore, it is necessary to analyze the characteristics of urban population structure changes, so as to more effectively adopt relevant policy measures, rationally guide and plan the public service planning for different types of urban population.

摘要：

在新一轮城镇化进程中，以人力资本为核心的创新经济逐步成为推动经济增长的动力引擎，省域中心城市作为人口聚集地的功能日益凸显。人口流动倾向影响着不同规模和行政等级城市之间的城镇体系重构，选取各个省域典型城市作为重点分析对象，通过我国城市人口最新数据统计测算，揭示出近期全国城镇化发展态势与大都市区域格局变化特征。结果发现，我国人口城镇化发展态势逐渐趋于平稳，不同地区、不同规模城市对人口的吸纳能力仍存在显著差异，各类直辖市、省会城市、副省级城市在人口集聚方面表现突出，传统港口城市、工业城市、省域副中心城市的人口吸引力逐步趋弱。其中，一级城市人口吸纳能力超强，二级城市成为人口重要集聚地，三级城市人口增速趋缓，四级城市人口吸引力平稳；可将之划分为“高/低规模”“高/低增长”四种不同组合类型。同时，城市人口的增长变化和人力资本竞争，显著影响了城市区域经济发展，特别是中西部地区省域中心城市实力日益增强，人口增长强劲，进而改变了传统东中西区域经济显著分异的格局，省会城市首位度表现出“高/低位序”“高/低集中”四种不同组合分布特征，且集中于“高位序、高集中”和“低位序、低集中”两种类型，分化格局相对明显。伴随着中国大都市的不断发育成熟，其逐步成为新时代创新经济和人口集聚的引领者。
