Abstract:	The arrangement of R&D staff refers to the issue of the linkage between structural holes in a network. In order to examine the linkages between multiple R&D projects in a company, we use the patent information as the index of R&D capability and examine our propositions by social network analysis. In this paper we focus on top-shared companies in Japanese cosmetic industry, and suppose that these companies keep their market shares due to their smoothly changes of business fields to cope with the threat of new comers from other industries. The analysis in this paper include: 1) calculate the betweenness centrality, and create heat maps to visualize the change of the betweenness centrality, 2) examine the structural hole.
