주택재개발사업의 토지자산평가액 변동률 분석

As the real estate market is in a state of depression, the expected profit from house redevelopment projects is decreasing. To proceed the project without delay, it is necessary to obtain residents' consent, and therefore objective and scientific data of evaluation on expected profit is required in the planning phase. Looking into the structure of profit generation and distribution of house redevelopment projects, a sensible cost estimation is possible, while a reliable prediction of land value fluctuation rate before and after the project is very difficult, despite the rate has strong influence on the development charges to residents. Thus, this study tried to analyze how the variables of location, status and planning factors affect land value fluctuation rate using ridge and principal component regression. Research data were collected from 44 zones where house redevelopment projects have been implemented. The empirical research finds that the land price has fluctuated wildly where the zone is located in comparatively poor conditions of transportation and education. In addition, it is shown that, if the land value fluctuation rate has positive relations with the ratio of housing sites and household density, then it has negative relations with site area, average area of shares and ratio of national land to purchase.
