소득계층별 거주가능주택의 주거분리 특성 분석 : 수도권을 중심으로

Abstract

This study aimed to investigate spatial segregation patterns of affordable housing by the income group using apartment price and rent data between 2011 and 2015 for the Seoul metropolitan area(SMA). In doing so, we calculated housing affordability index(HAI), rental affordability index (RAI), and housing opportunity index(HOI). Furthermore, we analyzed spatial segregation patterns for disposable income deciles in terms of unevenness, concentration, centralization, and clustering indices. Major findings can be summarized as follows. First, the analysis results show that both the lowest and highest income groups have higher uneveness indices than other groups, indicating a serious spatial segregation for those groups. Second, the high income group is likely to have higher concentration index than low income group. Third, centralization index shows that housings for the high income group locate near the CBD of Seoul, while housings for the low income group locate in the outskirt of the SMA, implying a residential segregation between the central city and suburbs.
