This study purposed to examine what factors will have a higher influence on apartment price in the future by analyzing trends in the influence of price determining factors on apartment price. In the past, constructors churned out stereotyped apartments, but from now on they should supply apartments fittingly to the characteristics of each region. This study may be helpful to meet such a requirement. Moreover, it may be useful for local self‐governing bodies to make local policies related to housing supply.
The scope of this study was 636 households at 37 complexes among apartments within a 1km radius from the housing development districts at Ildo dong, Ido 2 dong and Nohyeong dong in Jeju City constructed during the period from 2002 to 2009.
Chapter Ⅰ presented the background, objectives, scope and methods of research, and Chapter Ⅱ examined the current state of the housing market and the trends of apartment price. Chapter Ⅲ reviewed previous studies related to factors determining apartment price, and those related to the dynamic analysis of factors influencing local markets and apartment price. Chapter Ⅳ selected variables and formulated a hedonic price model, and then chose variables, and Chapter Ⅴ analyzed correlations among the variables, and performed dynamic analysis on price determining factors by estimating the hedonic price model. Chapter Ⅵ Conclusions mentioned the results and summaries of analyses in this study, the limitations of this study, and policy suggestions.
As to research methodology, we used actual apartment price as a dependent variable, and selected a total of 50 explanatory variables. Then, we formulated a hedonic price model and then, by converting the model into a double log function, chose 9 explanatory variables. The correlations among the variables were determined by Pearson’s test through bivariate correlation analysis using SPSS 19. If there are cases in which the correlation between two variables is strong, there may be multicollinearity. This was tested with variance inflation factor (VIF). As all the variables used in this study had VIF less than 10, they were adopted as effective variables.
The variables chosen in this study were size, the number of households by size, the number of bathrooms, building age, oversize, the use of city gas, and brand value as physical characteristics, the number of schools as a location characteristic, and view to Mt. Halla as an environmental characteristic. When the hedonic model was estimated, the adjusted coefficient of determination of all these variables was over 95%, showing high explanatory power.
According to the results of this study, the rate of change in the factor, which is the size of change in the influence of a price determining factor on apartment price, based on year 2002 was largest as 18% point in building age, which was followed by oversize, the number of bathrooms, the number of schools, brand value, the use of city gas, the number of households by size, and view to Mt. Halla.
Specifically, first, the influence of view to Mt. Halla on apartment price in Jeju City was weak as around 2.2% point. This is because Jeju City has an urban structure going down steeply away from Mt. Halla toward the sea.
Second, the influences of the number of households by size, the use of city gas, and the number of schools on apartment price were, respectively, 3.4% point, 7.1% point and 8.7% point. This suggests that buyers’ preference for complex type apartments is high because elementary schools are located within such complexes and, as a result, neighborhood living facilities are concentrated on such areas.
Third, the influences of oversize and the number of bathrooms on apartment price were, respectively, 10.5% point and 9.3% point. This suggests that most of apartments supplied in the Jeju area are of medium or large size and buyers also prefer medium or large size apartments.
Fourth, the influence of building age on apartment price was changed from ‐-0.430 in 2002 to -0.250 in 2009. This shows that there is a stable demand for old apartments in the apartment market of Jeju City.
Fifth, the influence of brand value on apartment price increased to around 8.3% point. This indicates that the influence of brand value is increasing recently in the apartment market of Jeju City.
