  ABSTRACT: Drawing on social information processing theory, this study adopts a third-party observer perspective to examine the mechanisms through which observed coworker helping behavior influences employees’ knowledge sharing behavior, as well as the boundary conditions of this relationship. Using data collected from 297 participants, we develop and test a moderated dual-mediation model. The results show that observed coworker helping behavior has a double-edged effect on knowledge sharing behavior. On the one hand, it promotes knowledge sharing behavior by enhancing employees’ perceived cooperative norms; on the other hand, it inhibits knowledge sharing behavior by increasing employees’ perceived workplace ostracism. Further analyses reveal that task interdependence strengthens the positive effect of observed coworker helping behavior on perceived cooperative norms while weakening its positive effect on perceived workplace ostracism, thereby further moderating the two indirect pathways. This study extends research on helping behavior by introducing a third-party perspective and uncovers the dual mechanisms and contextual dependence underlying the effect of observed coworker helping behavior on employees’ knowledge sharing behavior.
