Abstract: As the first step toward a study of complex networks in economics, we consider business networks categorized into bipartite networks. Through empirical study we show the possibility that business networks will fall into the scale-free category. To have an idea about the clustering coefficient and the averaged path length for bipartite networks, we perform a one-mode reduction. We calculate the quantities for networks constructed by banks and companies before/after a merger among banks, and quantitatively show that the merger among banks increases the cliquishness of companies and decreases the typical separation between two companies.
