  • Internal redeployment versus external recruitment of inventors

    Sea-Jin Chang, Yoichi Matsumoto

    Research Policy 54 ( 6 ) 105238 2025.07

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  0048-7333

    　View Summary

    Firms must recruit external talent while strategically redeploying incumbent inventors across projects to maximize the value of their inventor resources. This study examines how firms can balance external recruitment and internal redeployment of inventors within the global semiconductor industry. Our findings suggest that inventors with less central positions in a firm's knowledge network are more likely to be redeployed to similar technology areas. External hires, in particular, are more likely to be redeployed compared to incumbents, possibly due to their lower opportunity costs. However, external hires tend to be redeployed to firms' incumbent technology areas rather than new ones, except when firms enter new technology areas by hiring individuals with prior experience in those areas. This approach indicates that firms may prioritize inventor productivity over possible opportunity costs to enhance the success of new technology entry.

  • Dynamic resource redeployment in global semiconductor firms

    Chang S.J, Matsumoto Y

    Strategic Management Journal 43 ( 2 ) 237 - 265 2022.02

    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.

    　View Summary

    The results of this research project are the following three points.
    Firstly, this project produced the theoretical basis of Business Ecosystem research as the review paper published on the global leading academic journal. Business Ecosystem is the one of the new research field in the business strategy theory. Secondly, on the basis of theoretical research, the multiple studies on specific case has published. Thirdly, the research project developed the methodology for the visualization of Business Ecosystem. Based on the visualization of the dynamics of the business ecosystem, the mechanism of the Business Ecosystem evolution has discussed.
    In the future, further theoretical development and methodological development are needed in policies and businesses that are becoming more complex, and applications to UAV (Unmanned Aerial Vehicle), AI (Artificial Intelligence) and autonomous driving are expected.

  • Strategic rigidity in Japanese companies

    　View Summary

    This study investigated why organizations could not change.
    At first we tried to consider it theoretically. We analyzed the interactions between individual's decision and organizational activities, and we found they bounded each other. Thus, to overcome the rigidity, we can suggest that organizations have to replace both conventional way of decision making and that of organizational management simultaneously.
    As a second stage project, we executed empirical research for organizational rigidity. We used both quantitative and qualitative approaches: statistical examination of Japanese overseas subsidiaries in emerging markets and case analysis of Sharp Corporation. Both indicated our theoretical considerations would be valid, and the way to escape from rigidity were also examined.
