This paper addresses an important knowledge gap regarding the internationalization of family businesses. To understand the specific factors that influence the internationalization of these firms, this paper investigates the role and articulation of entrepreneurial orientation (EO) and family social capital (FSC) on internationalization performance. Our findings reveal that the more entrepreneurial the family business, the higher the likelihood of identifying and exploiting business opportunities in foreign markets. The moderating effect that FSC can have on the dynamics between EO and internationalization indicates that this relational family specific asset facilitates organizational stability and performance enhancement.
