Research On The Differentiation Of Living Space Of New Immigrants In Nanjing Based On The Five-pile Data Of The Neighborhood Committee

With the rapid development of opening-up and urbanization,large numbers of rural surplus labors moved into the city and residents in small cities settled down in economically developed metropolitan.After entering 21 century,those immigrants had a deep impact on the urban residential space.This paper matches the fifth census data at the community level with an accurate map,studies the spatial distribution of new immigrants in Nanjing and characteristics of their residential space and analyzes the reasons for this phenomenon.It can help enrich the domestic study about urban social-spatial transformation at the community scale.Moreover,the study of residential-spatial of immigrants is instructive to the urban planning of Nanjing.This paper describes the related concepts of new immigrants and residential-spatial differentiation,then comprehensively analyze the relevant researches of urban residential-spatial differentiation both at home and abroad,especially the research of immigrants,providing a theoretical basis for this research.Based on the fifth population census data of 2000 at the community level,this paper examines the residential-spatial differentiation of urban and suburban areas of Nanjing in 2000:Firstly,six factors that influence the social spatial structure of Nanjing are extracted from the census data with the method of ecological factorial analysis.By the use of social area analysis and hierarchical clustering method,the urban and suburban areas are divided into 6 different types of social areas.Then the text explores the characteristics of immigrants in the 6 social areas.Afterwards this article discusses the main factors and the social effects of residential-spatial differentiation based on the above analysis.Finally,suggestions are put forward to reasonably guide the residential-spatial differentiation in Nanjing.The main conclusions of this paper including the followings:(1)There are 6 types of social areas in Nanjing urban and suburban areas,including groups living in public houses,residential district of intellectuals and industrial labors etc.those areas show a strong mixing characteristics;(2)By calculating the location quotient of new immigrants in each social area,it can be detected new immigrants are concentrated in newly built residential areas and districts of manufacturing labors.But few immigrants are in residential areas of intellectuals and industrial labors and districts of farmers and the old.And the differential degree of manufacturing residential areas is 0.31,the highest of all.Residents from traditional service department and the unemployment is 0.19,the lowest of all;(3)Socio-economic,institutional and marketing factors are responsible for the residential-spatial differentiation of immigrants.(4)Although residential-spatial differentiation of new immigrants in Nanjing has brought some positive effects,more attention should be paid to the negative influences.Considering the negative effects of residential-spatial differentiation,several feasible strategies such as enhancing the infrastructure construction and providing housing benefits are raised to reduce the negative influence of Nanjing residential-spatial differentiation.
