The role of family management and family ownership in diversification: The case of family business groups

This study undertook a panel data analysis of the top 100 family business groups in Taiwan between the years 1988 and 2002 to investigate the role of family management and family ownership structures in diversification using an agency theory approach. The results show that, in the institutional context under study, family management and family ownership play key roles in diversification decisions in family business groups. Specifically, the likelihood of diversification declines as a controlling family assigns more family members to an affiliate firm’s key leadership positions. In contrast, the level of diversification increases as the degree of pyramidal ownership structure increases. The research findings presented in this study (1) clarify the roles that family management and the pyramidal ownership structure play in the diversification decisions of family business groups and (2) provide insights into family business groups’ growth.
