The Influence of the Structure of Interdependence on the Response to Inequity in Buyer–Supplier Relationships
研究买方-供应商关系中，正负不公平如何在不同相互依赖程度和相对依赖下影响供应商的资源分享及关系绩效感知，基于日本供应商与美国买方的纵向调查数据。
This research investigates the conditions under which inequity in a buyer–supplier relationship influences a supplier's resource sharing with its buyer. More specifically, the authors examine the effects of both positive inequity and negative inequity under varying levels of interdependence magnitude and relative dependence. They further examine the effect of inequity on perceived relationship performance. The study includes a longitudinal survey design, with perceived relationship performance reported by a second informant. The study, conducted within the context of Japanese suppliers reporting on their relationship with U.S. buyers, takes a nuanced view of both inequity and relative dependence by employing spline variables to disentangle potentially different effects of positive and negative inequity and relative dependence of the supplier and buyer, respectively. The results reveal that firms' reactions to positive and negative inequity vary depending on the nature of the interdependence structure and that positive and negative inequity differentially influence perceived relationship performance. The findings are important for both further research and managerial action.
