This study focuses on business relationships in Japan for industries pertaining to dyeing and finishing. The authors analyzed complex networks of 3354 companies contained in the Annual Report on the Textile-Related Trade, 1998 edition published by Sen-I Sha Company. Based on the community extraction proposed by Newman in 2004, there are forty-six communities in complex network and two large competitive communities containing a lot of dyeing and finishing companies are existed. As results of community extraction of complex network that deletes one big company on the betweenness centrality, the structure of the community is changed. [ABSTRACT FROM AUTHOR]
