Social-spatial characteristics and issues of large affordable housing area in urban outskirts:A case study of Daishan,Nanjing City
Urban affordable housing communities are often located in suburbs,and these large communities have increasingly become focal points in urban social geography research due to the unique social,economic,and cultural attributes of their residents,the impact of affordable housing communities on residents'employment,lifestyle,and behavioral patterns,as well as the urban social-spatial issues such as residential spatial differentiation and resource distribution disparities induced by the construction of affordable housing.To address the deficiencies in relevant existing studies,including the lack of big data,comprehensive samples,and multi-dimensional,small-scale analyses,this study selected Daishan,the largest affordable housing area in Nanjing City,as the research object.Using 21 residential communities(groups)within the area as spatial units,and utilizing mobile user profiles and questionnaire survey data,combined with social,spatial,behavioral,and perceptual factors,this study investigated the social-spatial characteristics and issues of large affordable housing districts on urban outskirts.The findings reveal that the Daishan area exhibits characteristics such as aggregation of vulnerable groups,insufficient service facilities,heavy commuting burdens,and weak community belonging.While the social space across the area is relatively homogeneous,residents of communities with high concentration of public rental housing have the poorest economic conditions.Conversely,areas with better environmental and residential quality tend to house high-income young professionals.Future development in the area must pay attention to potential risks such as the perpetuation of poverty,community decline,and social discrimination.By integrating big data and conventional data sources to explore social spaces on a fine-grained spatial scale,this approach effectively compensates for the deficiencies of traditional data sources,such as socioeconomic statistics and sample questionnaire survey.This enables a nuanced exploration of urban social-spatial phenomena,providing detailed and authentic insights into the complexities and issues within social spaces.
