Development of Methods in Application to Multiple-relational and Multi-modal Inter-corporate Networks

Kanamitsu开发并形式化了一个三方中心性模型来衡量三重二元企业间网络的中心性得分，作为二部网络中心性的延伸。他还开发了一个董事派遣模型，而不是董事联锁模型，以便更好地捕捉日本公司间的董事会关系。与Soma和Inoue一起对共同专利网络（以及某些情况下的交易网络）进行了广泛的研究；特别是他在研究共同专利和交易网络的多重网络时，发现了日本多部门工业网络中“交易驱动的创新扩散”模式。我们在企业间网络研究方面做出了重大贡献，出版了大量书籍和论文。

Kanamitsu developed and formalized a tripartite centrality model to measure centrality scores on triple dyadic inter-corporate networks as an extension of bipartite network centrality. He also developed a model for director dispatches rather than director interlocks in order to better capture Japanese inter-firm directorate ties.Along with Soma and Inoue extensively did research on co-patenting networks (and transaction networks in some case) ; especially he found a pattern of "transaction-driven diffusion of innovations" on Japanese multi-sector industrial networks when he looked at multiple networks of co-patenting and transaction networks. We made substantial contributions to inter-corporate network research publishing a large number of books and papers.
