Stemming from resource dependence theory this article investigates the mediating role of international entrepreneurial orientation on the relationship between the involvement of non-family members in the firms' governance structure and both pace of internationalization and international performance of family firms. Relying on a sample of 113 German family firms, the theoretical model proposed in the study is tested via structural equation modeling techniques. Our findings suggest that a high involvement of non-family members in governance structure has a positive impact on family firms' pace of internationalization, and that this relationship is mediated by the international entrepreneurial orientation of the firm. The discussion section offers implications for family business and international entrepreneurship literature, as well as practical implications.
