Abstract:    The importance of international opportunities has become increasingly prominent due to the development of globalization. Born globals, as a special kind of international start-up enterprises, born with an international vision and enter the international market at the beginning of establishment. It has always been the focus of research in the academic that how born globals overcome the characteristics of small scale and lack of resources, and occupy a core position in the complex and changeable international competitive environment. 
    Ambidextrous innovation is an effective means for enterprises to gain competitive advantage, and more and more born globals have gradually realized that whether they can achieve equilibrium between exploratory innovation and exploitative innovation will directly affect their international entrepreneurial performance. On the one hand, they are opposite because they seize the limited resources, so enterprises need to strike a balance between the two. On the other hand, they can promote, complement and benefit each other to overcome the drawbacks of a single innovation model, and enterprises can pursue both high exploration and high exploitation. It′s necessary to explore that whether the equilibrium between the two can promote the international entrepreneurial performance of born globals. 
    Connections between enterprises can affect innovation and entrepreneurship of enterprises. Social network, as a significant social capital, is a way for enterprises to obtain resources, which is conducive to the realization of innovation and the improvement of entrepreneurial performance. Born globals locate in domestic and foreign markets, with abundant opportunities and extensive information channels. In addition, the results of social networks are reflected in many aspects, not only in the transformation of innovation, so it′s worth exploring that whether social network has the same role for born globals, as well as how it plays an impact between ambidextrous innovation and international entrepreneurial performance. Therefore, based on the theories of organizational ambidexterity and social network, this paper uses Stata 16.0 software to analyze the panel data of born globals in China from 2011 to 2020. 
    The first purpose of this study is to explore the impact of the balanced dimension and complementary dimension of ambidextrous innovation on their international entrepreneurial performance. And the second purpose is to explore the moderating effect of social network centrality and structural holes, so we construct social network based on the concurrent relationship between directors of enterprises, Ucinet6 software is used to calculate the centrality and structural holes. 
    The results of study in this paper are as follows: The balance dimension and complementary dimension of ambidextrous innovation both have positive effects on the international entrepreneurial performance of born globals. The centrality, as well as structural holes both have negative moderating effects on the relationship between the complementary dimension of ambidextrous innovation and the international entrepreneurial performance, but have no moderating effects on the balanced dimension. 
    The theoretical contributions of this paper include the following two aspects. Firstly, it further confirms the relationship between ambidextrous innovation and the international entrepreneurial performance of born globals. We incorporate the balanced dimension and complementary dimension into the study, enrich the research field of ambidextrous innovation and international entrepreneurship, and provide new research ideas for the influencing factors of the international entrepreneurial performance of born globals. Secondly, it further reveals the influence mechanism of social network between the ambidextrous innovation of born globals as well as the output of international entrepreneurship, and illustrates the negative moderating effect of centrality and structural holes. 

Key words:  ambidextrous equilibrium innovation, international entrepreneurship, centrality, structural hole, born global
