It is well known that infrastructure networks like telecommunications, freight and person trip play a very important role in the social activities and that the facilities of these networks constantly change in both quality and quantity. There have been developed some models to analyze their structures, they treated only the static data. This paper proposes an extension of the structure to deal with the dynamic interrelationship changes model, combining the spatial interaction model and multidimensional scaling model. This model employs the polar coordinate to clarify the dynamic convergence or divergence behavior among regions. In this paper, we applied it to the analyze telecommunications, freight, and person trip OD data. The mainfinding are as follows: 1. telecommunication shows single ring pattern, converging around Tokyo, 2. freight transportation network gives some clusters converging around Tokyo and Osaka, 3. person trip network indicates intermediate pattern between those of telecommunication and freight.
