Abstract:Existing research has pointed out the importance of knowledge stock and knowledge exchange in building knowledge integration mechanisms, but doesn't uncover how international ambidexterity strategy impacts knowledge integration mechanisms. This paper divides knowledge integration into formal and informal integration mechanisms and empirically tests the impact of international ambidexterity on two integration mechanisms and the moderating effect of international knowledge dimensions. The results show that international ambidexterity is positively related to both formal and informal knowledge integration mechanisms. The relationship between international ambidexterity and formal knowledge integration mechanisms is moderated by international knowledge breadth and depth, the relationship between international ambidexterity and informal knowledge integration mechanisms is moderated by international knowledge depth and tacitness. Theoretical and managerial implications are discussed.
