영문 초록

The graph theory method which is developed by Nystuen & Dacey(l96l) has been widely applied for nodal regionalization by using interaction 0-D matrices. One desirable property of the Nystuen & Dacey model is the inclusion of indirect flows in addition to direct flows. But there are some problems in this model, its names, the interpretation and magnitude of indirect flows. The results of this study are as follows: CD there are no indirect flows by way of direct flows concerning flows such as passengers, commodities, and money itself. Thus, it is not necessary to consider indirect flows. Indirect flows is interpreted as transfer of information through passengers, commodities, and money among regiöns; @The proper adjacency matrix lS a η =x ij /Pj The Nysten & Dacey model and the new model to the trips of commuters in Jejs Prefecture was applied in this study. By comparison, the new model proved to be more appropriate to the information transfer by direct commuters. Therefore, the new model was found to be more useful.
