Application of analysis and modeling of complex business relation network
Center for TDB-Advanced Data Analysis and Modeling Tokyo Institute of Technology, Tokyo 226-8502, Japan
Statistics of business firms is characterized by power law distributions and power law scaling relations among various quantities such as annual sales, number of employees and number of business partners . Complicated trading relation among firms is described by evolution model based on creation-annihilation-aggregation processes , and basin structure of money flow can be estimated by a generalized gravity interaction model . Percolation analysis is applied to this trading network, and precise value of percolation threshold and critical exponents are evaluated . We introduce a recent application of our business network modeling in the field of policy making, RESAS .
