  • Dynamic resource redeployment in global semiconductor firms

    Chang S.J, Matsumoto Y

    Strategic Management Journal 43 ( 2 ) 237 - 265 2022

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  01432095

     View Summary

    This study explores how firms decide in which businesses to further invest and from which businesses to withdraw resources by examining the detailed product portfolios of firms in the global semiconductor industry. Results show that resource redeployment within incumbent businesses is more prevalent than via new entry or complete exit, since the former is more flexible and easily reversible than the latter. This study further finds that, while underutilized resources may drive resource redeployment, resource shortage by a newly entered or expanding incumbent business may also siphon resources away from other incumbent businesses, leading to their exit or temporary retrenchment. Fabless firms with resource that are more fungible, scalable, and decomposable vis-a-vis integrated device manufacturers show a more flexible and gradual pattern of resource redeployment. Managerial summary: In fast-moving environments, firms should quickly redeploy resources to more promising business areas. We find fabless firms with more fungible, scale free, and decomposable resources engage in more active resource redeployment than integrated device manufacturers with specialized fabs and equipment, like Intel or Samsung. Redeployment among the latter requires a well-planned, synchronized approach so as to avoid idle resources. As such, in order to take advantage of dynamic resource redeployment, managers should begin by assessing the characteristics of firm resources along these dimensions. Managers may also consider business model transformation to separate their activities by specializing in areas in which they can best utilize their resources and capabilities, like fabless firms and foundries in the semiconductor industry.

  • A review of the ecosystem concept — Towards coherent ecosystem design

    MasaharuTsujimoto, Yuya Kajikawa, JunichiTomita, Yoichi Matsumoto

    Technological Forecasting and Social Change (Elsevier)  136   49 - 58 2018.11

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  00401625

     View Summary

    The ecosystem concept is of increasing significance in the field of the management of technology and innovation. This paper provides an overview of 90 previous studies using the ecosystem concept in this field, all published in leading academic journals, and clarifies their four major research streams. The first stream is the industrial ecology perspective, which is based on the concept of industrial ecosystems. The second is the business ecosystem perspective. This approach is based on the theory of organizational boundaries. Within the business ecosystem perspective, some influential scholars emphasize platform management, which represents the third approach. The fourth approach is the multi-actor network perspective, which contributes dynamic behavioral relationship analyses based on social network theory. This perspective expands the range of analysis to include a variety of actors in addition to private companies. As a result of the review, this study presents an integrated model of the existing literature. Furthermore, this paper proposes original definitions of the ecosystem and the concept of a coherent ecosystem. This coherency is the core concept underlying the explanation of the dynamic evolution or extinction of the ecosystem. Finally, this paper discusses the significance of the ecosystem concept and indicates topics for future research.

  • Finding the 'boundary mediators' : network analysis of the joint R&D project between Toyota and Panasonic

    Masaharu Tsujimoto, Yoichi Matsumoto, Kiyonori Sakakibara


    Research paper (scientific journal), Joint Work, Accepted,  ISSN  02675730

     View Summary

    In recent years, a large and growing number of companies have attempted to develop core technologies for their products by conducting joint research with a company in a different industry. However, the mechanisms by which technologies are acquired and assimilated through cross-industry research remains unclear. In response to this ambiguity, we developed a theoretical framework for this mechanism, proposed hypotheses, and empirically examined data from a joint research project conducted by Toyota Motor Corporation and Panasonic Corporation to develop the nickel-hydrogen storage cell. Specifically, we analysed networks of inventors who filed patent applications through the joint research. The results indicate that there are 'boundary mediators' who facilitated the exchange of technologies between the two companies. On the basis of their wide range of technical knowledge, we found there to be two types of boundary mediators.
