“…Although there are a number of studies that have investigated how CEO origin, family businesses as a whole analytical unit, or family ownership influences innovations, the difference in how family heirs and unrelated internal successors affect innovation has been less explored (for a review, please see Karaevli, ; Massis, Frattini, & Lichtenthaler, ). As innovation performance significantly affects the competitive advantage and survival of a firm, it is particularly important for both scholars and professionals to understand how such performance is impacted by successor origin, and especially family heirs, due to the impact of family effect (Colot & Bauweraerts, ). In this study, by incorporating the perspective of family effect with upper echelons theory, we not only divided successor origin into external and internal categories, but also further disentangled the latter into unrelated internal and family CEOs, which provides a better understanding of the differences in the ways that unrelated internal successors affect innovation performance as well as the effects that family heirs have on innovation performance.…”
