上海人口空间变迁的现象、原因及后果初探

依托人口普查和经济普查的数据平台，对2000—2010年上海市人口的居住和就业的空间变迁进行较为详实的呈现。研究发现，上海常住人口的居住空间变迁有2个特点：居住空间呈现圈层特征，其密度向外递减，且随着时间推移不断向外扩散；同时，不同年龄组人口在居住空间上呈现高度分化的态势。造成这种变迁现象的一个主要原因是劳动年龄的净迁入人口大量进入中心城周边地区。人口普查和经济普查数据的叠加分析表现出这样一种现象：就业在中心城区的空间聚集度远高于居住，而向中心城周边地区的扩散速度则远低于居住，其后果是职住分离状况的加剧。在上海市应对未来人口规模的持续增长的情境下，该研究可提供一个基于城市功能与空间结构调整的视角。

Phenomena,Causes and Consequences of Shanghai Population Spatial Change

Illustrated here is distinct job ＆amp; housing spatial change of Shanghai population during the year of 2000—2010, with data based on demographic census and economic census. It found out high-density living space spreading rapidly, while people of different age group live in different space. One explanation for these phenomena is the great lfow of working-age immigrants blooding into surrounding areas around city center. The analysis based on economic and population census shows that the spatial density of employment are higher than residence in city center, while the speed of defusing is lower, which would raise the level of job-housing separation. This research would offer a new perspective on urban function and spatial changing, in
