토지이용 접근성과 중심성의 토지가격 효과 연구: 서울시를 사례로

초록

We have less understanding of land use accessibility and centrality and their effects on the property market in urban studies. This study aims to measure the land use accessibility and centrality and isolates their effects on the land price in Seoul, 2010. The accessibility and centrality indices contain Reach, Gravity Index, Betweenness, Closeness, and Straightness. The indices were calculated by street network attributes and building volume of each use. Thus, we could measure the spatial pattern of the accessibility and centrality. The model obtains the different response of land price to the indices. The model outputs confirm that Reach, Closeness, and Straightness for residential buildings tend to increase land price while five indices for commercial and office buildings all generate positive effects on the price. The non-residential buildings conferred the premium in land price. The indices for industrial buildings, however, were negatively associated with the land price due to the negative externality of the buildings. This study suggests that access to the commercial buildings has generated remarkable effects on the parcel price in the neighborhood. The results provide insightful policy implication for delving into urban spatial structure and designing public policy. The urban policy should take into account the interaction among the density of land use, urban form, and network features.
