재건축 가능성에 따른 서울시 권역 간 아파트 가격차이 비교 연구

초록

This study empirically analyzed the effect of redevelopment expectations on the price per land share according to the building age of each Seoul area. In particular, it was intended to check whether the building age effect was indiscriminately reflected according to the characteristics of the region where the supply period and supply scale of apartments were different. For this study, 44,828 transaction cases were divided into southeast, southwest, city-center, and northeast regions; multiple regression analysis by region was conducted; and the difference was verified through variance analysis. Based on the analysis, first, as stated in previous studies, it was confirmed that the price per land share according to the building age was nonlinear in all areas. Prices fell as the building age elapsed. After a certain point, prices rebounded owing to expectations for improved residential environments and economic benefits from redevelopment. Second, it was confirmed that the change in price per land share according to the building age had an indiscriminate effect between areas with similar supply sizes and apartment supply timing. Third, it was confirmed that the price effect according to the building age appeared differently between the areas where the supply period of the apartment and the supply scale were different. Through additional analysis of variance and post-test, it can be observed that the difference in regression coefficient values can be divided into three groups: southeast / city-center / southwest & northeast. Based on this study, the price effect according to the building age varies by timing and size of supply rather than by region. It has been revealed that similar supply timing and supply scale of apartments are characteristics that affect areas indiscriminately regardless of the region. Furthermore, the necessity of establishing a differentiated redevelopment policy was proposed considering the characteristics of each region with similar development background and formation period.
