Visualization of business networks

Abstract

We propose a method of visualizing business networks in order to connect the knowledge of complex networks and actual business. Although business networks are constructed with various economic agents and complex relationships, we consider only networks constructed with listed companies and shareholding relationships. We propose a center of mass method to draw a global map of business networks, and visualize that four major banks have a strong influence on almost every listed company. We also propose a visualization method based on the construction of stock portfolios, and draw a local map centered on the bank.
