Abstract
Prior research on knowledge sharing has focused on individual-level, team-level or organizational-level analyses. High-commitment HRM is regarded as a commitment-based strategy which may foster employee motivation that contributes to knowledge sharing. A multiple-level analysis was adopted to investigate relationships among high-commitment HRM, perceived organizational support, trust, and knowledge sharing. Samples collected by this study obtained from 27 financial institutes in Taiwan, including 177 supervisors and 926 subordinates. Individual-level results showed that positive relationships existed in relations between perceived organizational support, trust, and knowledge sharing. Trust partially mediated the relationship between perceived organizational support and knowledge sharing. Cross-level results represented that high-commitment HRM was positively associated with perceived organizational support.
