Abstract: 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. Additionally, based on the reference paper, the presenter will indicate the research process of the Ecosystem and the Example of the application to the Hydrogen Energy Ecosystem, Contactless ICPayment System Ecosystem and Autonomous Driving Ecosystem. For the discussion, the author will propose the Ecosystem Design Process and evaluation criteria.
