This study examines the influences of knowledge-sharing activities and tertius iungens orientation on job performance within social media environments. It introduces individual factors (knowledge self-efficacy and enjoyment of helping) and social factors (social interaction ties and the norm of reciprocity) as antecedents, based on social cognitive and social capital theories. Through empirical analysis, it finds that knowledge self-efficacy, social interaction ties, and the norm of reciprocity positively influence knowledge-sharing activities in social media environments, and that social interaction ties and the norm of reciprocity contribute to the establishment of an individual’s tertius iungens orientation only through knowledge-sharing activities. In terms of job performance, it shows that tertius iungens orientation plays a mediating role in the relationship between knowledge-sharing activities and individual job performance. Our results have important theoretical implications for researchers of topics such as knowledge management in social media contexts, and offer a helpful perspective for managers who hope to introduce social media within their organizations in order to facilitate the conducting of job duties.
