Structural Characteristics of Venture Companies Network in Japanese Biotech Industry

摘要

Bio-tech venture companies' which have broad alliance network tend to grow and to be listed (=IPO). In addition, it is necessary for venture companies to accumulate internal resources and capability. That is, both structural characteristics of the network and internal resources are important for the venture growth in the pharmaceutical industries. As an analysis target, we covered 186 pharmaceutical manufacturing and reagent manufacturing venture companies established in Japan, from 1995 to 2015. Then we classified our collection of data mainly into three groups; IPO ventures, subsidiaries and others. With our data, analysis of variance was conducted. As a result of analyzing partnerships, IPO ventures have different positions from other companies in ‘betweenness’. That is, IPO ventures partly have the function as the bridge of the research and development group in the network.
