Network Sharing beyond Knowledge Sharing: The Mediating Role of Tertius Iungens Orientation in Social Media Contexts

This study examines the influences of knowledge-sharing activities and tertius iungens orientation on job performance within social media environments. 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. The results are expected to provide important theoretical and practical implications for researchers and practitioners respectively.
