Peer knowledge sharing and organizational performance: the role of leadership support and knowledge management success

Purpose This study aims to focus on a particular type of intra-organizational knowledge sharing that is referred to as peer knowledge sharing. This paper examines how peer knowledge sharing impacts firms’ financial and innovation performance, and the mechanism through which such a relationship is realized. The study also evaluates the extent to which leadership support acts as a key antecedent to peer knowledge sharing. Design/methodology/approach Drawing on social capital theory and a knowledge-based view of firms, a theoretical model and related hypotheses are presented for testing. A survey design methodology is used to collect data and test the model. Structural equation modeling is used to test the hypothesized relationships based on data collected from 330 knowledge workers in various service-based organizations in Turkey. Findings The results indicate that the extent of employees’ engagement in knowledge sharing behavior with their peers and their managers’ leadership support exert a positive impact on organizations’ knowledge management success, which, in turn, can affect organizations’ innovation performance positively and, subsequently, their financial performance. Leadership support of the immediate manager is found to be an important factor that contributes to the respondent’s peer knowledge sharing behavior. The proposed model’s invariance testing between male and female respondents revealed that peer knowledge sharing’s contribution to knowledge management success may be different in the two groups. Research limitations/implications This study contributes to extant research on knowledge sharing by specifically focusing on peer knowledge sharing and reinforcing leadership support’s importance on knowledge sharing. The study also highlights the importance of knowledge management success as an important mediator necessary for linking individual knowledge management behaviors, such as peer knowledge sharing, with organizational performance. Originality/value Knowledge sharing is a topic of continuing interest for organizational researchers, yet limited empirical research has been conducted that links individual-level, intra-organizational knowledge sharing to organizational performance. This study examines this linkage and provides empirical support for this relationship, while simultaneously pointing to an important type of knowledge sharing that occurs within organizations, referred to as peer knowledge sharing.
