| Outline of Final Research Achievements |
By analyzing big-data about 1 million business firms, we firstly confirmed that the transaction network has typical properties of complex networks such as power law distribution of link numbers. We then observe the amount of flow between pairs and established a nonlinear transport relation in the framework so-called gravity law. Generalizing this pairwise relation to the whole network system, we constructed a nonlinear transport model which enables estimation of flow intensity at any point. Additionally, we defined a new quantity that characterizes fragility of network connectivity by applying theory of percolation.
