In this study, we analyzed the overseas branches of Chinese companies listed on the A-share market that expanded internationally between 2007 and 2018. Using social network theory and the Cox proportional hazards model, we explored how migration networks influence the survival of these subsidiaries. Our findings show that migration networks significantly enhance the survival rates of overseas subsidiaries of Emerging Market Multinational Corporations (EMNCs). Additionally, the mode of entry plays a mediating role in this relationship, particularly in areas with strong migration networks. We also found that subsidiaries established as sole ventures are more likely to survive.
