摘要：R&D internationalization has become an important way for MNEs (Multinational Enterprises) to acquire global innovation knowledge. The research on knowledge acquisition strategies during the process of R&D internationalization may play a guiding role for MNEs. In this paper, through the systematic review, the existing research is summarized according to the logic of Why- Where-How . The results show that the establishment of R&D units by MNEs is only the first step of knowledge acquisition strategy. At unit level, hiring excellent R&D talents and collaboration are the two main ways to acquire knowledge. Furthermore, the interaction between R&D units and external organizations and the knowledge flow between internal units can truly promote MNEs’ innovation ability. At last, this paper also proposes possible future research directions for existing research.
