Knowledge sharing through cross-border strategic alliances has been seen by firms as one of the critical strategies to pursue sustainable competitive advantage. However, empirical investigations on how knowledge sharing occurs in strategic alliances are limited and are rarely concerned with strategic alliances in the higher education industry. Based on an empirical investigation of China–UK educational alliances, this research sheds light on this under explored area. Findings reveal that the scale of academic and organizational knowledge sharing is affected by knowledge attributes and partner characteristics. While knowledge sharing in China–UK higher education alliances displays numerous similarities with that occurring in other industries, this study reveals features that are distinct to this important and increasingly international sector. In so doing, this paper offers valuable insights for managers and policy makers concerned with the internationalization of higher education.
