Research in social network has demonstrated that firms in changing environment will benefit from innovation network. However, the lack of consensus on what factors and how these factors impact the performance impedes the further research in this area. In this paper, the concept of international innovation network and its performance are clarified. Then, based on reviews of the social network and knowledge management literature, especially along with the results of previous empirical studies, we propose an integrative model in which the performance of focal firm within international innovation network is impacted by network structure (network range and density), network relationship (tie strength, duration, and norm distance), and network position (centrality). We also come up with some efforts that the firm can make in order to improve its performance. In the end, the future research following this study is discussed.
