英文摘要：

At present, most research on internationalization of SMEs adopt theoretical frameworks such as the re- source-based view, transaction cost theory, the increasing knowledge-based views, or the risk management theories, while ignore the great influence of psychological and cognitive factors of top managers on their firms. Through the empirical research of 105 SMEs in Jiangsu Province, this article explored the relationships between entrepre- neurs＇ perceptions of global competition stress, a psychological and cognitive characteristic of top management, and the behavior of intemational expansion of their enterprises. The results demonstrated that an inverted-U shape curvilinear relationship between entrepreneurs＇ perceptions of global competition stress and the behavior of interna- tional expansion of their enterprises and international market orientation can be served as a moderator in this cur- vilinear relationship
