In any economic structure of a region with regard to supply and demand, one of the important criteria is freight flow that exists between regions. It was ascertained that ton-km of freight flow by rail is the most important in Korea.In this thesis, an attempt is made to clarify the spatial pattern and to build traffic core regions. This is to clarify the characteristics of traffic core regions on freight flow by railroads in Korea.For this purpose the flow pattern of freight was analysed by the Q-mode and the R-mode factors. Traffic core regions determined by group average and multiple linkage analyses, and the character of the origin and destination were analysed.Flow data in this paper emanate from matrices produced by the Office of the Korean National Railroads contained in part in their publication estimates of Korean Inter-Zonal Freight Flow, 1977. Estimates were produced by total rail freight flow (tons) between 56 zones.Major findings are as follows:(1) Freight flow by origin and destination by rail determind 10 types of flow patterns. In addition, this flow structure was added to local and regional flows on the basis of national flow (double stucture).(2) In the traffic core regions that resulted by analysis of the flow pattern, there are 8 traffic core regions by outflow (Cheolam, Gohan, Dogye-Bugpyeong, Ssangryong-Jecheon, Daecheon, Yeosu-Hwasun, Mungyeong, Ulsan) and traffic core regions by inflow were builded 2 regions (Seoul, Busan).(3) Centralality was measured by eigenvalue and factor score, and the order of traffic core regions by outflow consisted of Ulsan, Gohan, Cheolam, Ssangryong-Jecheon, Mungyeong, Yeosu-Hwasun, Dogye-Bugpyeong and Daecheon. The order of traffic core regions by inflow consisted of Seoul and Busan.(4) The traffic core regions by outflow are constituted by regions producing underground resources and heavy-chemical manufacture. Traffic core regions by inflow are constituted by large consuming and developed areas of manufacturing. Finally it may be difficult to determine the factor of freight flow by rail; however, it is explained more or less by the relationship between underground resources, population and manufacturing in Korea.
