Abstract:  By examining population growth after 1958 in each region of Beijing and population by current residence and usual residence 5 years ago in each region of Beijing at the Fourth and Fifth National Population Census,this article explores the question if the City of Beijing has stepped into the stage of suburbanization,arguing that it is inappropriate to view Urban Function Extended Region totally as the suburbs or the city proper.It is necessary to differentiate the population pertaining to township,town and urban subdistrict in order to look at separately the suburbs and the city proper within the Urban Function Extended Region.As the population growth rate of Core Region of Capital Function has declined,the population growth rates of both Urban Function Extended Region including the near suburbs and New Region of Urban Development located in the outer suburbs have increased since the 1980s,and the population growth rate of New Region of Urban Development has surpassed that of Urban Function Extended Region in recent years,the article claims that the urbanization process of Beijing has entered into the suburbanization stage.

摘要： 通过对北京市各类区域自1958年以来的人口增长速度以及"四普"和"五普"时北京市各类区域按现住地和五年前常住地分的人口数据的分析,本文对北京市是否进入了郊区化阶段的问题进行了探讨。认为,把北京市的城市功能拓展区全部看作是近郊区或全部看作是城区都是不恰当的。在对北京市的郊区化问题进行研究的时候,需要分乡、镇、街道的人口数据,这样才能对拓展区内部的城区和近郊区分别进行研究。由于自20世纪80年代以来首都功能核心区人口增长率下降、包含近郊区的城市功能拓展区和属于远郊区的城市发展新区人口增长率上升以及近年来发展新区人口增长率超过拓展区,本文认为:北京市的城市化进程已经进入了郊区化阶段。
