Due to long-term economic recession and change in population structure due to low birth rate and aging, the city is in new demand along with low growth era. There have been various social changes along with low growth. Especially, the city faces various problems such as decline of old downtown, collapse of root industry, severed community. Various types of urban problems are expected to last. In Korea, the number of vacant house is increasing centering around declining and older areas. As of 2015, there are 1.06 million vacant houses in Korea. Vacant house and its management plan became a significant issue in urban planning. Vacant house causes various external effect which lead to various social problems. For this reason, it justifies the intervention of public on vacant house problem. There have been various studies about the issue, but they lack in quality and quantity. Most of the studies only focus on utilization measure, and conduct fragmentary researches. To resist the generation of vacant house and efficiently manage them, studying original property of vacant house is of utmost importance. In this context, one must focus on cause and location property of vacant house. By apprehending the cause of vacant house and its location property, vacant house can be resisted and prevent spreding course. Thus, this study aims to resist the vacant house through understanding influential factors of vacant house and its location property, and suggest political suggestion to improve utility of vacant house management.
To examine the cause of vacant house, it used spatial econometrics model. To confirm the spatial cluster, the study verified spatial auto -correlation using Moran''s I index. Also, to examine the location property of vacant house in each region, the study applied Poisson regression.
According to analysis result, the study confirmed that Korea lack in clear definition about vacant house or relevant fundamental statistics. This is a huge obstacle in conducting various researches to solve the problem. Vacant house has significant spatial aggregation and forms cluster. Also, such spatial cluster of vacant house tend to adhere while spreading to neighborhood at the same time. Nextly, according to spatial econometrics model to examine the influential factor, changes in population structure due to low birth, aging and changes in local economy structure was the major cause of vacant houses. Also, location of various convenience facilities and its accessibility had significant causal relationship with vacant houses. Finally, the location property of vacant house differed by local property and urban scale. In this context, it justifies a reason to examine the local and location property differently for future vacant house management policy.
Based on the study results, the study''s political suggestions are as follows. First, the public managing authorities of vacant house problem such as government or local government must focus on adhesion and spreading process of vacant house to resist generation of vacant house or efficient management of the problem. Also, the universal objectivity regarding definition of vacant house, terms and statistics must be secured. Next, as the study confirmed the locational property of vacant house is different, the managing body of vacant house project must be local government who can reflect local property of the vacant house rather than the central government. Finally, government and local government must conduct selective preferential policy targeting regions where the causes of vacant house are concentrated and spatial cluster of vacant house is strongly formed based on this study''s result.
