ABSTRACT Drawing on the perspectives of technology affordance and organizational learning, this study examines the relationship between individual-level mobile knowledge-sharing intentions and behavior, as well as the moderating effects of exploratory and exploitative knowledge-sharing activities within teams in the public sector. Data were gathered through a questionnaire survey distributed to 377 public employees in 31 mobile knowledge-sharing teams in Taiwan. The results show that mobile knowledge-sharing intentions positively predict behaviour at the individual level. Additionally, exploratory knowledge-sharing activities at the team level amplify the positive impact of mobile knowledge-sharing intentions on behaviour at the individual level. The study reveals that Information Technology (IT) exerts a more substantial influence on exploratory activities than on exploitative activities, particularly among civil servants who have confidence in new technology.
