Knowledge sharing in collaborative supply chains: Twin effects of trust and power

Knowledge sharing has been recognised as a key enhancer of supply-chain performance. However, the sharing of knowledge may not take place easily and automatically among the supply-chain partners. This paper attempts to shed some light on the mechanisms underpinning knowledge sharing in supply chains. In particular, we focus on knowledge sharing in a dyadic buyer-supplier relationship. We posit that trust and power are two important antecedents of two types of knowledge sharing between a buyer and supplier, namely technical exchange and technology transfer. To build our research model, a large-scale mail survey was conducted from a contact list of 800 companies provided by the Singapore Logistics Association. The results of the structural equation modelling suggest that trust has significant effects on technical exchange and technology transfer. Further, power also affects technical exchange and technology transfer significantly, though the impacts appear to be weaker than trust. The theoretical and practical implications of this research are discussed.
