Received international business and international human resource management theories have generally reached a consensus on the important role of leader and top management teams (TMTs) in deciding and shaping the firm’s internationalization process. However, what remains unclear is how a well-functioning TMT is formed to effectively achieve the desired internationalization goal. Utilizing a unique sample of Chinese banking and finance institutions’ initial public offering overseas, this study explores how Chinese BFIs configure the leader-TMT dynamics to achieve high internationalization performance. Using a set-theoretic approach and the technique of fuzzy-set qualitative comparative analysis, a distinct taxonomy of the leader-TMT dynamics (namely, grass-root, strategic executor, born-global and glocal) is developed. Our findings provide novel insights into the IHRM variations within Chinese BFIs’ TMT formation, based on a theoretically and methodologically extended leader-TMT dynamics perspective.
