교육시설을 통해서 본 도시 공간적 불균형 - 서울시 고등학교를 중심으로 -

The purpose of this study is to analyze the educational environment gap based on the educational performance in high schools in Seoul and the phenomenon of residential segregation based on individual income. This research analyses spatial characteristics of the proxy variable for the educational environment gap within the range of unit of the academic performances of high school students by using SAT scores and the income data of biz-GIS's on the phenomenon of residential segregation. The result shows that the phenomenon of residential segregation caused by the educational environment was clearly revealed. Second, the residential segregation is almost identical with the spatial distribution of educational environment gaps. Finally, the educational environment gap within the range of schools is a structural issue in society that is beyond the scope of one's individual abilities. As the results, this polarization constantly causes spatial inequality, so both policy and physical alternatives need to be implemented simultaneously to resolve it.
