Disseminating and sharing of knowledge is the corner stone of knowledge economy. It is, therefore, imperative to know the factors which could be instrumental in this distribution. The purpose of this research is to understand the relative importance of knowledge-sharing factors such as knowledge of the situation and social network (SN) on knowledge sharing in University of Peshawar. Data from 244 randomly selected respondents from the target population has been collected through a questionnaire. The questionnaire was tested for its validity and reliability. Multiple regression analysis has been employed to test hypotheses of the study. Findings indicate that knowledge of the situation and SN both are positive and significant predictors of knowledge sharing. However, among the two, SN happens to be a stronger influential factor within the overall model. This research addresses the gap on knowledge sharing in general and in Universities in particular which appears sparse. As a social research, the study has its limitations. This article contributes to the theoretical integration of Attitude-to-Behaviour process model and social capital and put to empirical testing on regional data. Organisations working on knowledge transfer programs may get benefit from the findings of this research. Recommendations for further research have also been provided.
