Currently, China is deepening the new development pattern of "dual circulation" and implementing the "Belt and Road" initiative, guiding enterprises to expand their global market layout. As an important pillar of the national economy, family businesses, during the special period of generational succession, have increasingly attracted academic attention for their inheritance effects on international development. Most existing research focuses on the correlation between governance structures and corporate performance, with less attention paid to the dynamic of generational succession and the characteristics of family businesses, particularly the mechanisms by which second-generation members participate in cross-border operations. This research gap holds significant theoretical innovation value and practical guidance significance during the intersection of transformation, upgrading, and inheritance. This study integrates social-emotional wealth theory with advanced theoretical frameworks, using stata17.0 statistical analysis tools to empirically examine panel data from Chinese family-owned listed companies between 2015 and 2022.In terms of academic contribution, this research has deeply expanded the explanatory boundaries of social-emotional wealth theory and advanced theories in the context of intergenerational inheritance. It constructs an analytical framework of "family characteristics-strategic choices," providing innovative theoretical tools for decoding the internal mechanisms of multinational business decisions in family firms. In practical application, the findings offer empirical evidence for family firms planning their international development paths amidst dual challenges of generational transition and strategic change. This helps companies achieve high-quality growth and long-term success through generational resource integration and strategic iteration in global competition.
