Korea has experiencing big changes with the appearance of retail facilities for a new status in retail distribution markets from the middle of 1990s. In this situation, the study analyzed the location tendency of retail facilities as the subject of investigation for the Ibaraki prefecture in Japan, which has early experienced various changes in retail markets than Korea.
The study, at first, observed the changes of a spatial distribution for retail facilities ranged from the 1970 to the year of 2000. The study, then, analyzed the location of retail facilities by construction of a location tendency model to examine the changes of the spacial distribution. In the analysis of location tendencies, the presumption by cross-sectional data of a singleness point in time in analyzing the location tendencies can explain only inter-regional differences of the distribution of retail facilities in the point of time. This presumption, however, may not explain the spatio-temporal changes of retail facilities in terms of dynamic changes with time. Therefore, the study to examine the spatio-temporal dynamic changes by inferring the location tendency model with the cross-sectional data at first defined the need to assume the panel data and its model. After this, the study inferred the location tendency of retail facilities by extending the panel data model from the location tendency model. As the result, the panel data model could simultaneously explained inter-regional differences and intra-regional changes of the location of retail facilities. In addition, the study could much more clearly investigated the location tendency of retail facilities in Japan, which has shown secular, dynamic changes
