1. CONTENTS (1) RESEARCH OBJECTIVES This research has analyzed the mwor changes according to 3 separate areas Area 1 including Kangnam-Gu and 4 adjacent Gu, Area2 including other areas excluding Area 1 beneath Han River, and Area 3 above Han River. This research objectives are (1) to conduct a comparison analysis on the time-manner change of the increase expectancy in residential unit prices for the consecutive 3 years from 2005 to 2008, in which the major changes of residential unit prices were observed on the regional basis, and (2) to conduct a comparison analysis on the time-manner change of preference determinants on selecting various residential units for the same period of time. (2) RESEARCH METHOD This research mainly utilized SAS program to obtain the precise statistical analysis over the collected data, and Likert Type Scale was used to verify preference determinants on selecting various residential units and regional differences. Also, T-test was conducted to discover the yearly average difference of each determinants and Logit. Analysis was conducted to find out yearly and regional analysis over the future preference determinants on selecting various residential units. (3) RESEARCH FINDING Because this research has selected only a few determinants from the previous researches in order to facilitate the overall analysis procedures, it might not catch the specific, meticulous changes, which a research with various determinants may catch. In addition, because of the limitation on the research term and confined research samples, this research might not have a long-term time-series analysis result and particular determinants. In the next researches, various and detailed long-term time-series analysis is needed. 2. RESULTS In case of Area 1, among the determinants, investment purpose determinant was found to be relatively more important in 2006, when the high price increase was observed. In contrast, that investment purpose determinant were found to be less significant in 2007 and 2008, when the price decrease was observed. This result confirms the general public understanding of the high correlation of the price charge in residental units and investment purpose determinant. On the other hand, as the residential unit price decreases, other determinants such as the neighborhood interrelations shows more significant instead of investment purpose determinant. Other results includes that unlike Area 1, determinants such as rush hour time and public transportation means were found to be highly significant in Area 2 and Area 3. In case of Area 1, even though the residential unit price showed decrease, but the determinants over investment purpose is found to be significant in 2007 and 2008, when the price has showed an increase.
