市场转型期中国大城市低收入社区住房分异研究

Housing Differentiation in Low-Income Neighbourhoods in Large Chinese Cities under Market Transition

基于2007年在广州、武汉、西安3个大城市的低收入社区开展的大型入户调查数据,在社区尺度探究了中国大城市低收入社区中不同社会经济群体间的住房分异情况,并分析了在社会经济转型背景下的制度因素(如户口、邻里类型、雇主类型等)和市场因素(如社会群体、年龄、受教育程度、家庭收入、职业等)对住房产权和居住条件的影响。通过计算泰尔指数发现,大城市低收入社区中不同群体间和群体内的住房分异情况都较显著,但群体内部的差异较群体间的差异更为明显。对住房条件的多元回归分析结果表明,低收入社区不同社会群体的住房条件在不同程度上受到制度因素和市场因素的影响。制度因素对住房面积等难以在短时间内改变的住房条件的作用较市场因素更显著,而市场因素对于住房设施等较易改变的住房条件的影响要比制度因素明显。

Based on a large-scale household survey conducted in low-income urban neighborhoods in three large Chinese cities,i.e.Guangzhou,Wuhan and Xi′an,this study examines China′s low income urban neighborhoods＇ between-group and within-group housing differentiation defined by different socioeconomic characteristics,and analyzes various determinants of housing differentiation under market transition,including institutional factors（hukou,neighborhood type,employer type,etc.） and market factors（social group,age,education,Household income,occupation,etc.）.This study aims to present a comprehensive portrait of housing differentiation in low-income urban neighborhoods,and to understand how the confluence of state and market forces contribute to housing differentiation.The merits of this study mainly lie in two aspects：first,based on first-hand data source,this article presents a meticulous examination of housing differentiation within and between groups categorized by various indicators;second,this study enriches our understanding of the role of institutional and market forces by providing a more accurate assessment on their respective impacts on different aspects of housing differentiation.In this study,we applied various statistical models to analyze different social groups＇ housing differentiation on the housing tenure and housing conditions.Theil′s index is applied to measuring the degree of residential differentiation between and within groups on housing tenure and housing conditions,while multivariate regression model is used to explain the causes of housing conditions differentiation.According to the Theil′s T statistics,the differentiation of housing tenure is most significant among people with different hukou status.These findings suggest that housing tenure differentiation is predominantly shaped by institutional factors,while the impact of market remuneration system,e.g.educational attainment and household income,is comparatively less significant.The patterns of differentiation are slightly different when it is measured by housing conditions.In terms of between group differentiation in housing conditions,groups defined by hukou status,household income,and different cities show a high degree of differentiation.In comparison,between group differentiation is much less significant than within group differentiation.This could be partly explained by the fact that various social groups in Chinese cities are generally characterized by high degree of heterogeneity and mobility under market transition.This is particularly true among residents in low-income neighborhoods,which are highly fluid,volatile,and heterogeneous,although they might become more homogeneous once all better-off residents have moved out.The multivariate regression analyses reveal that the forces from market and the state have brought about different imprints on various aspects of housing status.Institutional factors have projected more significant impacts on some costly and durable housing indicators,which are less likely to change in a short period,such as housing tenure and housing area,while socio-economic determinants are more influential on housing facilities which are comparatively easy to be improved.Concurring with extant literature,this study shows that institutional heritages from the socialist period continue to shape the patterns of housing consumption in post-reform large Chinese cities,although the newly emerged urban housing market starts to play increasing important roles.In addition,this research presents a much more detailed portrait of housing differentiation in low income neighborhoods.This paper has added much richness and nuance to extant understanding of housing differentiation under market transition.
