Universities need to be aware of the impact of knowledge management (KM) in order to become world-class academic institutions. This research fills an unexplored gap in regards to the impact of KM enablers (i.e. trust, knowledge self-efficacy, reciprocal benefits, top management support, organizational rewards, organizational culture, KM system infrastructure and KM system quality, openness in communication, and face-to-face (F2F) interactive communication) on knowledge sharing (KS) that supports research collaboration by faculty members. No prior research has focused on the impact of KM enablers that influence research university members to share knowledge. A self-administered questionnaire was employed on members of five research universities in Malaysia to collect data; subsequently, 421 usable responses were analysed using partial least squares path modelling. KS by members was influenced by trust, organizational rewards, organizational culture, KM system quality, openness in communication, and F2F interactive communication; in addition, research collaboration was strongly influenced by KS. The KM–KS–collaboration model shows a KM influence of individual–organizational–technological–communication constructs that encourages KS by members to support research collaboration.
