研究了供应商依赖如何调节买方公平（分配公平与程序公平）对供应商信任的影响，基于动机认知视角，通过调查和案例验证了不同依赖水平下公平效应的差异。
ABSTRACT Distributive fairness (how benefits are shared) and process fairness (how decisions are made) are key antecedents to trust formation in buyer–supplier relationships. However, existing research has given limited attention to when and how distributive and process fairness are associated with higher trust, especially considering the motivational components of trust. Drawing on a motivated cognition perspective, this study examines how supplier dependence—a key factor that shapes supplier motivation—moderates the relationship between buyer fairness and supplier trust. Survey data were first used to investigate the moderating effects, demonstrating distinct patterns of fairness effects across different levels of supplier dependence. A case study was then utilized to strengthen the research's applicability in real‐life situations, particularly to illuminate the mechanism of motivated cognition. This study advances knowledge in two important ways. First, it provides a fuller specification of the fairness–trust connection in buyer–supplier relationships. Second, it generates novel insights into trust as a motivated phenomenon.
