摘要
随着我国城市普遍进入存量发展阶段,人口与企业在城市建成区内部的迁移是否意味着城市局部的经济衰退,是值得关注的问题。文章选择东北传统工业城市沈阳市辖区为实证研究范围。以街道、区、城市作为分析空间单元,采用兴趣点(Point of Interest,POI)数据对人口真实变化进行空间分析。同时,采用国企和外企统计资料,在市辖各区和街道两个空间尺度上,测算企业的进入率和退出率。文章指出,在不同的时空尺度下,企业和就业机会的增减不完全反应城市建成地区是否存在局部收缩现象;有时两者的变化趋势并不具有一致性。但是,人口和企业迁入地区仍然可作为识别城市内部活力空间的依据。
With the process of generally entering the stock development era in China cities,the migration of population and enterprises within the urban built-up areas worth paying more attention,because it related the economic recession in the city.This research chooses the traditional industrial city Shenyang of northeast China as the research object.Subdistrict,districts and municipal districts are used as spatial units,and POI data are used to analyze the real changes of the population.Meanwhile,using the statistical data of state-owned-enterprises(SOEs)and foreign enterprises(FEs),this research calculates the entry rate and exit rate of enterprises on districts and subdistricts level.It is pointed out that at different spatial and temporal scales,that means spatio-temporal scale effects(STSE),the increase and decrease of enterprises and employment opportunities does not completely reflect the local shrinkage in urban areas;sometimes the two trends are not consistent.However,the population and enterprise migration area can still be used as the basis for identifying the vitality space within the build-up urban area.
