  • The distinctiveness and diversity of entrepreneurial ecosystems in China, Japan, and South Korea: an exploratory analysis

    Martin Hemmert, Adam R. Cross, Masahiro Kotosaka, et, al.

    Asian Business & Management (Springer Nature)  18 ( 3 ) 1 - 37 2019.05

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  14724782

     View Summary

    © 2019, Springer Nature Limited. Entrepreneurial ecosystems at the regional level have been intensively studied in Western countries, but much less so in East Asia. We study five major ecosystems located in Tokyo, Seoul, Beijing, Suzhou, and Chongqing, focusing on the business conditions for information technology (IT) start-ups. Our domain analysis reveals that these entrepreneurial ecosystems differ in various important aspects from leading Western counterparts such as Silicon Valley. Furthermore, we find differences in the growth and internationalization of firms across entrepreneurial ecosystems in China, Japan, and South Korea. Public policy should focus on supporting high-potential start-ups and strengthening the ecosystems’ global outreach.

  • Field Transformations: Cross-Field and Intra-Field Institutional Work in Entrepreneurial Ecosystems

    Agata Kapturkiewicz and Masahiro Kotosaka

    Academy of Management Annual Meeting (Boston, MA) , 2019, Oral Presentation(general), Academy of Management

     View Summary

    We examine the long-term transformations of an emerging industry exchange field of the ICT entrepreneurial ecosystem in Japan, and the possible field-to-field interactions in these. A distinction between cross-field and intra-field institutional work is drawn and used as a lens to analyse data. We investigate institutional work on interactions (the informal interactions in virtual and physical spaces), intersections (the more formalised and structural arrangements that govern resources and shared issues), and interfaces (the communication protocols that affect interactions among actors) that relate to the resources of financing and labour. The data is based on qualitative interviews with selected ecosystem stakeholders. The findings contribute to the study of organisational fields and institutional work, and the nascent scholarship on entrepreneurial ecosystems as fields. Key insights are: 1) for an emerging industry exchange field functioning within a mature business system, if there is incompatibility between the fields, high power imbalance and low mutual resource dependence, it is the intra-field institutional work that matters more for the field’s development; 2) institutional work on intersections alone is insufficient for the development of comprehensive linkages between heterogenous actors within the field or across fields – the work on interactions and interfaces is also needed; 3) the main underlying mechanism for the intra-field institutional work that lead to the field’s development across phases is the cross-generational networking related to financing and labour; 4) if a field is growing, the institutional work on one of the resources has an enhancing impact on the institutional work done on other resources.

  • Managing the Co-Habitation Process During Intra-Family Succession

    Innan Sasaki and Masahiro Kotosaka

    Academy of Management Annual Meeting (Boston, MA) , 2019, Oral Presentation(general), Academy of Management

     View Summary

    In family firms, the co-habitation of incumbent and successor during intra-family succession may be particularly challenging because of the tendency of the former to preserve traditional ways, and the eagerness of the latter to introduce changes with a view of future developments. Our longitudinal case study begins to shed light on the potential influence of nonfamily members on the unfolding of the co-habitation. Our analysis reveals three distinct types of nonfamily members, whom we label defenders, prospectors, and connectors, and their alternating and complementary roles in reconciling the past-orientation of the incumbent and the future-orientation of the successor.
