This study examines the role played by managerial attitude in network development for SME internationalization. The findings reveal that managerial proactiveness in network development for international expansion significantly influences network structure, content and governance. Specifically, this will lead to an increase in indirect relationships as well as overall network size. The diversity and strategic orientation of resources exchanged with other actors will also grow as a result of intentional network development. Trust represents the main governance mechanism and will be deliberately maintained and enhanced by managers who build networks for internationalization purposes. Based on the findings, managerial implications and future research avenues are discussed.
