    　View Summary

    In a period of technological changes, new entrants to an industry are able to take advantage of emerging technologies, while incumbent firms have difficulty following trends. This study examines the position of new entrants that develop existing technologies, by exploring the historical case of radical technological change from vacuum tube to transistor technology in the case of Ise Electronics. The study investigates the innovation process involved in extending an existing technology through an entrepreneurial venture. This case analysis suggests that the extension of existing technologies is made possible by developing them and embedding them in products utilizing an emerging technology, and that bridges between old and new technologies can be built through personal and professional connections formed within an existing industry.

  • How Did Silicon Valley Innovate Itself? : Enactment Process in Business Ecosystem

    Koichi Nakagawa, Hiroyuki Fukuchi, Genjiro Kosaka, Atsushi Akiike, Mizuki Kobayashi, Toshio Kobayashi

    Journal of Business Management   34 ( 34 ) 3 - 14  2014.12  [Refereed]

    　View Summary

    This study investigates a microfoundation of the structural change of business ecosystem. While previous studies point out environmental shocks and subsequent entrepreneurial behaviors, we focus on the effect of several actors' interactions within the ecosystem. By using the concept of Weick (1979)' s enactment, we build up the chain reaction framework of multiplayers' interpretation and action. Through an in-depth case study of the transition of Silicon Valley ecosystem from an IPO-centered model to a M&A-centered one, we illustrates how startups, established business companies, venture capitals and research institutes interact each other and how those interactions effect on ecosystem transition.

  • A Comparative Study on R&D Organizations in Specialized Manufacturer and Generalized Manufacturer: A Case Analysis in the Vacuum Fluorescent Display Industry

    Genjiro Kosaka

    Organizational Science   48 ( 1 ) 78 - 91  2014.09  [Refereed]

    　View Summary

    It is often pointed out that a specialized manufacturer ("specialist") is more competitive than a generalized manufacturer ("generalist"). This paper examines how a specialist could maintain long-term competitive advantages, especially in the technological development. An explanatory case study was conducted by comparing a small specialist Futaba and a big generalist NEC in the vacuum fluorescent display (VFD) industry.<BR>Based on the analysis of patent data at the firm level and the individual level, two types of R&D organizations were identified: a successive, crosssectoral and closely cooperated R&D organization in Futaba and an R&D organization in which personnel can be flexibly reallocated in NEC. NEC's composition of four technological fields of VFD radically changed, while Futaba's remained stable. This finding is different from the common understanding that typical Japanese big firms have succeeded in incremental innovations by a close-knit group of engineers. Instead, this paper demonstrates that the technological capability that is characteristic of Japanese firms has been maintained in a small specialist.

    　View Summary

    <p>It is often noted that a specialized manufacturer (or "specialist") is more competitive than a generalized manufacturer (or "generalist"). This paper examines how a specialist could maintain a long−term competitive advantage, and especially in technological development. An explanatory case study was conducted by comparing a small specialist, Futaba Corporation and a large generalist, NEC, in the vacuum fluorescent display (VFD) industry.<BR>Two types of R&D organizations were identified based on an analysis of firm−level and individual−level patent data: a successive, cross−sectoral, and closely cooperative R&D organization in Futaba, and an R&D organization in which personnel can be flexibly reallocated in NEC. The composition of NEC's four technological VFD fields radically changed, while Futaba Corporation's remained stable. This finding differs from the common understanding that typical large Japanese firms have succeeded in incremental innovation using a close−knit group of engineers. This paper instead demonstrates that the technological capability characteristic of Japanese firms has been maintained by a small specialist. </p>
