Active SNS users are leaders of their peer groups. The youths are dedicated to share knowledge and information on SNS in their daily lives. We explore the motivation drivers influencing university applicants’ online knowledge sharing behaviour on SNS. Using a survey questionnaire completed by 485 students who enrolled a university degree programme in various majors, the study found that perceived online relationship commitment had a direct, positive and significant effect (β=0.66, p<0.001) and the perceived growth need commitment also had a direct, positive and significant effect (β=0.21, p<0.001) toward online knowledge sharing behaviour, whereas perceived online attachment motivation had a significant but indirect effect on online knowledge sharing behaviour through perceived online relationship commitment. The proposed online knowledge sharing model explained 43% of the observed variance, and its implications are discussed.enPerceived online attachment motivationPerceived online relationship commitmentOnline knowledge sharing behaviorBook Chapter10.1007/978-3-319-08961-4_27
