Abstract
With the development of urbanization, the differentiation and polarization of social space is the main feature of urban fringe. In order to pursue economic benefits and out of the desire for urban life, a large number of immigrants enter the urban fringe areas which provide a large number of cheap rental housing, showing a strong mixed and heterogeneous residential space. Especially in Beijing Second Green Belt, there are not only aboriginal villages and towns, but also special villages and communities such as "express village", "takeaway village", "ant village" and "art village" which can accommodate the employment and residence of immigrants. But many residents are still only a "marginalized" role in urban construction and development, only realizing regional transfer, and failing to really enter into the society. Therefore, the research on the residential space differentiation and social integration of the typical settlements of Beijing Second Green Belt has become an important entry point for the sustainable development of mega cities. However, many scholars at home and abroad ignore the differences of individual attributes in the migrant population, and the research scale is generally from housing to city, while the research on community scale is less. Therefore, this paper selects three communities in Cuigezhuang township, a typical area of Beijing Second Green Belt as the research objects, and takes Hegezhuang village (the resident village of artists and other immigrants), Jingwang community (the relocation community of local residents in each village after the demolition of Cuigezhuang township) as the research object Taking Dongxindian village (the resident village of taxi drivers and other resident villages) as an example, this paper tries to ensure the typicality and representativeness of the survey samples. This paper mainly adopts the methods of field survey, questionnaire interview, GPS, GIS and Stata. Based on the number, location and living conditions of different types of residents in the three communities, Moran'i index of GIS is used to reveal the characteristics of residential spatial differentiation; At the same time, GPS was used to collect the 24-hour activity types and paths of different residents to depict the spatial characteristics of residents' daily life and work behavior. Then, it constructs the social integration system of residents including economy, culture, psychology, social participation and communication. Through the processing of the questionnaire data, it calculates the integration index of different types of community residents. On this basis, we use Stata statistical software to establish a multiple regression model to analyze the main factors affecting integration. The results show that, firstly, three communities all show the phenomenon of residential space differentiation. The groups with different socio-economic status have different choices of residential space. The residents with high socio-economic status live in better living conditions, ordinary wage earners and office workers below middle income often live in a courtyard with more than a dozen people; Secondly, there are significant differences in the integration index between different types of community residents and the city, that is, the residents living in Jingwang community have a higher degree of social integration, and also show a positive attitude and good expectations for community affairs participation and communication, while the residents in Hegezhuang village and Dongxindian village have a lower degree of social integration; Third, the special urban planning structure of native place, economic income, occupation status, living environment, cultural level, housing ownership and the second green road are the main factors affecting residents' urban integration. The research results provide more comprehensive optimization strategies for the government in promoting and guiding the planning and transformation of Beijing Second Green Belt in urban fringe and promoting the social integration of residents.
