Although the characteristics of top managers is an important factor associated with competitive advantage, and managerial resources are recognized as a firm’s major resource, there is limited research concerning the role of top manager’s capabilities in the relationship between entrepreneurial orientation and international performance. Based on the upper echelons perspective and resource-based view, the present study aimed to analyze top manager’s cultural intelligence as an internal contingency of the relationship between entrepreneurial orientation and international performance. The study’s theoretically derived research model was tested using survey data obtained from 206 small- and medium-sized enterprises. The findings suggested that the extent to entrepreneurial orientation was related to a firm’s international performance was contingent on the level of three dimensions of cultural intelligence (metacognitive, cognitive, and motivational). Furthermore, as the level of all four cultural intelligence dimensions of top managers increased, the relationship between entrepreneurial orientation and international performance increased in strength. The implications of the present findings for future research and practice were discussed.
