This paper takes the companies that conducted cross border mergers and acquisitions in Chinese Shanghai and Shenzhen stock markets from 2009 to 2018 as a research sample, and uses a multiple regression model to empirically test the relationship between executives‘ overseas experience and cross border mergers and acquisitions. The research results show that: the overseas experience of executives helps to improve the cross border M&A behavior of their companies, and this conclusion still holds after multiple robustness tests; it’s no doubt altruistic behavior, but altruistic behavior improves corporate performance, supports the imprinting theory. The research of this paper not only enriches and expands the relevant research on the theory of high level echelon, but also has practical guiding significance for enterprises to realize the optimal allocation of resources through cross border mergers and acquisitions and to implement the “B&R Initiative. ”
