摘要
城市更新的社会价值及社会空间效应常在实践中被忽视。近年来,“城市更新引发多元社群空间再分布”已逐渐成为国内学界的普遍共识,但其中的具体影响机制尚不清晰、相对缺乏定量化的实证解析。以天津市内六区61个街道单元为研究对象,基于“城市更新时空演变图斑”和“街道尺度人口普查资料”两大类基础数据,借助多元线性回归、地理加权回归、空间回归系列模型,分别从特异性关联、空间非均影响、空间溢出效应3方面考察城市更新行动引发社会空间分异重构的基本逻辑和深层规律。结合天津实证并对比国际经验,总结提炼城市更新的社会空间影响路径及其本土特征,以期为存量转型期中国城市的高质量发展提供有益理论支撑。
The social value and socio-spatial effects of urban regeneration are often overlooked in practice.In recent years,it has become a general consensus in domestic academic circles that“urban regeneration triggers spatial redistribution of diverse social groups”.However,specific influencing mechanisms remain unclear and related quantitative empirical analysis is lacked.Taking 61 sub-districts of Tianjin as the research object,this paper carries out an in-depth study based on two categories of basic data:the spatio-temporal evolution pattern of urban regeneration and the census data of each subdistrict.Employing tools such as multiple linear regression,geographically weighted regression,and spatial regression models,the paper examines the basic logic and fundamental laws in the social space differentiation and restructuring caused by urban regeneration actions from three aspects,namely,specific correlation,uneven spatial impact,and spatial spillover effect.Comparing Tianjin’s empirical evidence with the international experience,this paper summarizes the socio-spatial impact path of urban regeneration and its local characteristics,in the hope of providing useful theoretical support for the high-quality development of Chinese cities in the period of transitioning to optimization of existing urban stocks.
