Abstract(in Japanese) (See Japanese page)
Abstract(in English) Flow on an interfirm trading network is interpreted as a money flow. Its contribution to the connected firm differs a lot according to the amount of flow. A lot of previous studies say flow on social network is known to obey a gravity-type interaction. By analyzing the data of firms' transaction, we found the same gravity interaction between firms in terms of money flow, and we reported money flow has characteristics of strong inequality caused by the interaction. We focused on the inequality and defined main stream by focusing on dominant flows. In this study, we proposed a method to extract dominant flow on a directed complex network and analyzed the method analytically.
