Abstract

The recent occurrence of vacant houses in urban areas is a remarkable social problem. One of the physical declines, the occurrence of vacant houses, accelerates various social and economic declines, such as a decline in population and a slump in the commercial district. Vacant houses have regional characteristics and spatial influence, and it is necessary to approach them locally in order to grasp the exact status of vacant houses. Therefore, in this study, the effect of urban decline on the occurrence of vacant homes was examined by region using global Moran's I and Geographic Weighted Regression(GWR) model. As a result of the analysis, there were spatial autocorrelation and heterogeneity in the occurrence of vacant houses in each eup·myeon·dong, Busan metropolitan city. In addition, there is a difference in the influence of each variable of urban decline on the occurrence of vacant houses, and even the same variable of urban decline has different effects on the occurrence of vacant houses in different regions. Therefore, it is expected that a more efficient vacant home management plan can be presented if the GWR model is used to analyze the coefficient values differentiated by region and categorize the occurrence of vacant houses.

최근 도시지역의 빈집 발생은 주목할 만한 사회문제이다. 물리적 쇠퇴 현상 중 하나인 빈집 발생은 인구감소, 상권침체 등 다양한 사회·경제적 쇠퇴를 가속화 시킨다. 빈집은 지역적 특성 및 공간적 영향력이 존재하며, 정확한 빈집 실태를 파악하기 위해서는 국지적으로 접근할 필요성이 있다. 이에 본 연구에서는 전역적 Moran's I와 지리가중회귀모델(GWR)을 활용하여 도시쇠퇴가 빈집 발생에 미치는 영향을 지역별로 살펴보았다. 분석 결과, 부산광역시 읍면동별 빈집 발생은 공간적 자기상관성 및 이질성이 존재하였다. 또한 각각의 도시쇠퇴 변수들이 빈집 발생에 미치는 영향이 차이가 있으며, 동일한 도시쇠퇴 변수라도 지역에 따라 빈집 발생에 미치는 영향력이 다르게 나타났다. 이에 GWR모델을 활용하여 지역별로 차별화된 계수 값을 해석하고 빈집 발생을 유형화 한다면 보다 효율적인 빈집 관리 방안을 제시할 수 있을 것으로 보여진다.
