Abstract
The commercial area of Seoul was formed as the linear on the streets from Jong-ro to Namdaemun-ro in the late of Chosun Dinasty. And it was revealed that it resulted from marketing system centered on the city and consumers' purchasing behavior through peddlers. In the Korean Empire Period after the opening port, because there still remained the marketing system centered on wholesale and consumers' purchasing behavior though foreign trade-people came into Seoul and especially Japanese commercial area expanded the whole area of Chungmu-ro and up to Namdaemun-ro, we can see that in this period the commercial area was informed as linear form on the city structure. But the re-establishment of Spatial Configuration of southwest-ro centered on Deoksu Palace made Namdaemun-ro more important area. And we can see that Japanese went to Namdaemun-ro because of its political, economical value. Though the commercial area which formed grid pattern of city structure in the Japanese occupation time was widespread with density on the main roads after Chosun Dynasty was annexed by Japan and through the city improvements, the commercial area became to expand to whole city areas. We can analyze that such change resulted from the expanding of the locational benefit of marketing system because of the formed grid pattern of city structure and growing retail trading, and that the distribution of shops was related to the number of Metric Angular Choice because of the improvement of regional approach. As a result, if we can interpret the change of commercial areas in the modern times with Spatial Configuration, linear commercial area on the city structure continued until the late of Chosun dynasty and then commercial area was expanding to whole city because of the grid pattern of Seoul city structure. This means that the commercial area formed in the city structure which Segment Angular Choice shows was changing regional center Metric Angular Choice shows. We can see that such change was due to the change of commercial areas and consumers' purchasing behavior. And it showed that Spatial Configuration of Seoul was related to the change of commercial area.
