How buyer-driven knowledge transfer activities affect supplier transparency in the food supply chain

Purpose The lack of transparent suppliers on the part of the buyer has caused significant reputational and economic losses for focal firms. Therefore, it is increasingly crucial to gain supplier support and response to enhance supply chain transparency in buyer-supplier relationships. However, the underlying impact mechanism of buyer-driven knowledge transfer activities on supplier transparency remains unclear. Thus, this study aims to utilize social exchange theory to reveal the impact mechanism of buyer-driven knowledge transfer activities on supplier transparency. Design/methodology/approach Based on structural equation modelling and regression analysis, data we collected from 408 food suppliers using a survey method to test the mediation model. Findings The findings of the study indicate that buyer-driven knowledge transfer activities not only have a direct positive impact on supplier transparency but also indirectly enhance it through supplier-perceived relationship transparency and the expected accessibility of buyer resources. Originality/value This study reveals the underlying impact mechanism of buyer-driven knowledge transfer activities on supplier transparency. It provides a new perspective from the supplier’s point of view to explore the impact mechanism of buyer behavior on supplier transparency. This not only contributes to a better understanding of the critical success path to enhance supplier transparency but also provides theoretical guidance for supply chain managers to enhance supply chain transparency and reduce the ripple effects of risks.
