AbstractThe impact of a firm's origins on its strategic decision‐making has attracted scholarly attention in recent years. Focusing on firms' origins, this paper explores the relationship between the privatization of state‐owned enterprises (SOEs) and family business internationalization. Based on data from listed family businesses in China from 2003 to 2022, we find that compared to entrepreneurial family businesses, restructured family businesses have a lower internationalization degree. Moreover, high trade policy uncertainty strengthens the negative relationship between the privatization of SOEs and family business internationalization, while high family involvement plays a weakening role. Several robustness tests later, the findings remain valid. This study introduces the firm's origin as a vital determinant, which may contribute to the prior studies on family business internationalization. Besides, this paper complements research on the economic consequences of the privatization of SOEs in China. Finally, this paper may help Chinese family businesses actively participate in the international cycle to achieve competitive advantage and high‐quality development.
