This research examines the determinants of knowledge sharing in university academic team utilizing an integrated model which posits that three sets of factors-knowledge-related, team member' motivation and personality, team climate influence knowledge sharing. Data were collected from respondent academic team members using online questionnaire. The results of the analysis demonstrate that all three aspects have a significantly influence on intention to share knowledge in academic team, mediated by attitude toward and subjective norm about knowledge sharing, and provide support for 9 of the 12 hypotheses. These research results extend, augment, and apply prior research to a seldom-discussed new domain: academic team. Our research contributes to theory and practice in academic team by focusing on knowledge sharing as the crucial aspect and integrating theory developed in other knowledge sharing contexts.
