Title:
An Analysis between Transaction
and Cross Shareholdings in the Keiretsu of Nissan
Abstract: Firm’s relationship is one of the important
issues in the field of corporate management. In this paper, the authors review
networks within the automotive industry, focusing on Nissan. Applying measures
of social network analysis, the authors calculate the centrality index of
data on transaction and cross shareholdings in the Keiretsu of Nissan’s network
to discover the strength of correlation between them. Centrality index are
calculated based upon “degree”, “betweenness” and “closeness” indicators.
And the central firm, periphery firm and radius and diameter of the keiretsu
are measured using graph theory. Compared with the result of earlier studies
on Toyota, extremely weak correlation between transaction and cross shareholdings
in the Keiretsu of Nissan have been found. Implications of the findings are
discussed.
