三菱商事における店舗ネットワークの構造と機能：1928-36年度

This paper explores the structure and function of the intra-firm trade network in Mitsubishi Corporation (Mitsubishi Shoji) from 1928 to 1936. In this period, Mitsubishi Co. substantially expanded its global branch network. Using original documents of Mitsubishi Co., we obtained the data on the trade flow between every pair of the headquarters and branches in 1928 and 1936. While the headquarters in Tokyo maintained its position as the central hub in the intra-firm trade network in this period, some major branches, including Dalian in China, grew to be the subsidiary hubs, which resulted in a change in the network structure.
