This is to study on the diffusion of supermarkets, an innovation in the Korean urban system. To clarify the process and the involved factors in their spreading, we examined their areal distribution. As their diffusion is closely related with the Korean urban system, it was compared with our previously verified dimensional characteristics of the Korean urban system (Sung, 1977) and with the hierarchical structure of the central place system (Sung, 1979b). Data were collected from 33 cities from 1968 to 1978, excluding such nonadoption cities as Kimcheon and Chungju. The main results are as follows: 1. The appearance and the diffusion of supermarkets imply a revolution of the retail system in Korean cities. The spatial distribution patterns of supermarkets can be classified into two types: the enterprises in the regional administrative centers and those in Seoul. To the former belong those whose head offices are in the regional administrative centers such as Daegu, Busan, Gwangju, and Daejon. They control all the cities under their influence. The latter are those whose head offices are in Seoul but whose branch offices are in the regional administrative centers of high population size and high centrality. They control all the cities within Korean urban system. The competition between the enterprises of Seoul and other regions are so severe that Seoul head offices meet with difficulties to set up their branches in the regional areas, and as a result the diffusion of Seoul branches are retarded. The correlation between adoption time (year) of supermarkets and the urban population size reveals γ=-0.774, which indicates that supermarkets tend to be adopted earlier in the larger urban centers (Tables 1-2 and Figs. 1-5).
