中国城市群人口流动问题探析——以沿海三大城市群为例

新型城镇化下着重以人为本的城市现代化建设,以沿海城市群为代表的三大核心城市群正在成为形成具有中国特色的区域发展模式与空间组合新模式。对沿海三大城市群城镇化过程中人口吸纳与流动过程的研究表明：① 城市群经济聚集的核心区域,人口聚集程度紧密且人口空间结构的集中化特征明显;② 城市群对流动人口吸纳能力不断增强,吸纳能力与城市群级别成正比;③ 在城市群区内人口流动结构的固定化方面,东部沿海城市是流动人口的首选区域,由西部向东部人口流入的趋势日益明显,人口流动将相对固定化,成为城镇人口的主要来源。这就需加强对城市群区内各大城市发展功能的深刻认识,并加强建设综合性城市管理数据库,分析城市群之间的内部联系及其城镇人口的合理安排,劳动力的地域分工与城市之间产业链的协作关系,以期达到更深刻的探索中国城市群的总体发育趋势的远大目标。

Population Mobility of Urban Agglomeration in China: A Case Study on the Three Coastal Agglomerations

New urbanization focuses on people-oriented urban modernization. Three core urban agglomerations represented by coastal urban agglomeration in China are becoming a new model of regional development and space combination with Chinese characteristics. This study on population absorption and flow process in the advancement of the three coastal urban agglomerations proves that: 1) In core areas of economic agglomeration, the degree of population aggregation is high, and the centralization characteristics of population spatial structure are obvious. 2) The ability of urban agglomeration to absorb floating population increased, and the absorption capacity is proportional to the level of urban agglomeration. 3) In the aspect of immobilization of population flow structure in the urban agglomeration area, eastern coastal cities are the preferred area for the floating population. Furthermore, the trend of population inflow from the west to the east is becoming increasingly obvious, and population flow is relatively immobilized, which becoming the main source of urban population. Strengthening the profound understanding of development functions of the major cities in urban agglomeration areas and enhancing the construction of a comprehensive city management database are necessary. In addition, analyzing the internal relations between urban agglomerations and the reasonable arrangement of the urban population, as well as the regional division of labor and the cooperation between cities in the industrial chain, are important to achieve a more profound exploration of the overall development trend of China’s urban agglomeration.
