The aim of the present study was to evaluate how the business-to-business (B2B) networks in the Japanese textile and apparel industry changed between 2005 and 2010 using data on 200 companies. Network analysis was used to study the properties of the B2B networks, and how their structures changed was characterized using the USD/JPY exchange rate. The network analysis revealed power-law properties of the B2B networks, and the core networks characterized by the largest degree centrality exhibited positive correlations with the USD/JPY exchange rate. By contrast, the peripheral networks characterized by the network path length exhibited the negative correlations with the exchange rate USD/JPY. Therefore, the changes that occurred in the B2B networks are explained as the complementarity of comparative advantages originating in the USD/JPY exchange rate. Moreover, the USD/JPY exchange rate affected the B2B networks through not only the complementarity of importing and exporting but also by changing the structures.

日本纺织服装业中B2B网络的变化结构

本研究的目的是使用200家公司的数据，评估2005年至2010年之间日本纺织服装行业的企业对企业（B2B）网络的变化。网络分析用于研究B2B网络的属性，并使用USD / JPY汇率表征其结构如何变化。网络分析揭示了B2B网络的幂律特性，以中央度最大的核心网络与美元/日元汇率呈正相关。相反，以网络路径长度为特征的外围网络与美元/日元汇率呈负相关。因此，B2B网络中发生的变化被解释为源自美元/日元汇率的比较优势的互补性。
