The purpose of this paper is to provide theoretical insights on the impact of supply chain collaboration on the operational performance of firms and collaborative advantage as an intermediate variable in the context of the supply networks of internationalized firms. The research is based on a case study of a distribution network constituting Russian and international firms. The obtained results indicate that supply chain collaboration improves operational performance of internationalized firms and firms in domestic market. Moreover, the study advocates that collaboration in distribution networks can be considered as driving factor for international firms to enter the emerging markets through supply networks.
