The Comparison of Hedonic Housing Price Models in the Busan Housing Market using Spatial Econometrics Methodology

This study is trying to find out the spatial econometrics model in order to reflect the true reality in the housing price analysis. Due to the influence of spatial autocorrelation with respects to the housing price in the housing market, the estimation of the OLS is not preferable. Then the spatial econometrics model reflecting spatial dependence and spatial heterogeneity is the best alternative in terms of housing price estimation, probably. Everything is related to everything else, but near things are more related than distant things . More realistic spatial weight matrix and spatial model scheme, better performance in the housing price prediction. Therefore, this study can show that the model improvement by spatial model scheme can be achieved by the comparing the spatial econometrics models such as SAR(Spatial Autoregressive Models), SEM(Spatial Errors Models), SAC(General Spatial Models), and GWR(Geographically Weighted Regression). Depends on the perspective of methodology, the SAC and the GWR models are preferable in terms of global(nomothetic approach) or local(idiographic approach) point of view, respectively.
