다국어 초록 (Multilingual Abstract)

This paper assesses changing patterns of the commercial power of a region and leading sectors of the movement with radial ring-based analyses of 49 categories of retail services in Kangnam-gu, Seoul. The radius of trade market area(R), as the measure of commercial power of a location, is defined as a pre-defined radial distance from the store location. Moving patterns of the regional commercial power is analysed based on the peak of overlapping density of the retail trade area every year. Findings indicate that the centers have been differentiated from each other in the form of an orderly hierarchy of places, with particular retail services developing for lower-ordered places as they reach a threshold, and leading sectors of the movement are usually retail services favored by teenagers.
