Purpose-The purpose of this paper is to help in providing a better understanding on knowledge sharing amongst academics in Higher Education Institutions (HEIs). The aim in this study is realized by profiling existing literature to understand the determinants of knowledge sharing, research trends, theories and future research opportunities. Design/methodology/approach-After carefully examining the extant literature, and by utilising relevant academic-based research databases, a total of 73 papers published in peer-reviewed journals over the last decade were reviewed and analysed using well established systematic literature review methodology. Findings-The adopted systematic review revealed that there is limited contributions in understanding knowledge sharing in HEIs when compared with other sectors. The review provides a number of avenues for future research including technological, cultural, organisational and behavioural aspects at different levels. Practical implications-This study helps in offering a focal point to senior management in HEIs for realising the requirements for developing appropriate strategies and programmes to promote knowledge sharing among academics and consequently enhance their institutions' performance. Originality/value-This study utilised Jesson et al. (2011) in presenting a comprehensive systematic review of knowledge sharing specifically in the context of HEIs. This paper offers some theoretical and practical insights on what contributes towards understating the determinates affecting knowledge sharing practices among academics.
