대도시광역권의 지역 간 네트워크 구조 변화

The purpose of this study is to figure out the structure of network between regions in Daejeon, Gwangju, Daegu and Busan metropolitan city areas composed of many cities and districts through social network analysis. This study investigated urban sprawl, centralization, spatial distance and how many city is networked for cooperation by analyzing network pattern between regions in metropolitan city areas from 1990 to 2005. As a result. metropolitan network structure in Korea shows that suburbanization is still progressing steadily and slowly while centralization in inner-cities is rapidly growing. Especially. Daejeon and Busan make rapid progress of centralization and suburbanization. And inter-regional network shows that the spatial distance is about 40km. Additionally, population is an important factor for this result. Finally, this result may be useful for making metropolitan plans.
