Hotspot analysis and future prospect of residential spatial differentiation research:Visual analysis based on CiteSpace
Since 2012,urban residential spatial differentiation has received increasing attention from the gov-ernment,society and academia.Sorting out its research context and development trend has important theoretic-al significance and practical value for subsequent theoretical research,planning and construction.With the help of bibliometrics and CiteSpace visualization,this paper analyzes domestic and foreign research literature on urban residential spatial differentiation.The results show that:1)The relevant research in foreign countries started earlier,and different schools of theory and practice research systems have been formed since the early 20th century;Domestic research started late but developed rapidly,and has entered a mature stage based on learning from foreign theories.2)The distribution of international authors is relatively scattered,but most of them have more cross-field and cross-institutional cooperation is more;However,the distribution of domestic authors is scattered and cross-field and cross-institutional cooperation is less,and universities are the backbone of their research.3)International research focuses on residential segregation,racial segregation,and spatial se-gregation,and quantitative model analysis,influencing factors and dynamic mechanisms are the research fron-tier and trend;In China,it mainly focuses on spatial differentiation,residential differentiation,residential spa-tial,and other aspects,and influencing factors and policy mechanisms are the frontier and trend of its research.Finally,the paper looks forward from the aspects of building a theoretical system with Chinese characteristics based on the national conditions,using the internet and big data to carry out innovative research,using multidi-mensional indicators to accurately detect residential spatial differentiation and early warning,focusing on small and medium-sized cities to enrich the study case,considering the scale effect combined with the differentiation mechanism to propose regulation strategies for urban residential spatial differentiation suitable for China's na-tional conditions.
