In this article, we explore the different roles that knowledge sharing and exploitative learning play in employees' innovative behaviour, and investigate the different moderating effects of employees' espoused national cultural values on the relationship between exploitative learning and innovative behaviour in the Chinese IT-enabled global service firms with different ownerships. We propose a theoretical model to characterize these antecedents of innovative behaviour. A structured research survey was conducted and data were collected from a sample of 484 full-time employees in 3 IT-enabled global service firms in the PRC. Results indicate that knowledge sharing is positively associated with innovative behaviour in multinational corporations and private IT-enabled global service; espoused power distance has a significant positive moderating effect on exploitative learning-innovative behaviour relationship in state-owned and private firms; espoused collectivism has a significant moderating effect only in state-owned firms in China. Last, we explore the implications of our findings for theory and practice of innovation.
