This study examines the component sourcing strategy of the Japanese automobile
manufacturers, focusing on the sourcing concentration and the sharing common suppliers
with competitors. We have analyzed sourcing strategy of six Japanese car assemblers
(Toyota, Nissan, Honda, Mitsubishi, Mazda, and Suzuki) regarding 95 components. We
have found that firms using a broad manufacturer-supplier network tend to be more
profitable. In other words, firms with a low sourcing concentration and a high supplier
sharing, which are the characteristics of quasi-market strategy, tend to perform better than
the other firms. Among the six manufacturers, Toyota, Mitsubishi, and Suzuki were
categolized as firms that followed quasi-market strategy.
We believe that this finding is interesting because this relationship has been found
in the context of the Japanese supplier-assembler relationship. The Japanese cooperative
inter-firm relationship is supposed to be beneficial to suppliers, as well as to assemblers. It
is commonly considered that a relatively exclusive keiretsu system facilitates these close
inter-firm ties. However, the results in this study imply that a few leading Japanese
automobile manufacturers may have management capabilities in benefiting from both a
relatively broad supplier base and cooperative relationship with individual suppliers. |
