We elaborate mechanisms through which multi-stakeholder collaboration can ameliorate food loss and waste (FLW) from the end-to-end supply chain. In this context, we integrate the discourse on collaborative relationships in supply chains with stakeholder theory (roles and orientations) and use a multi-method approach combining systematic literature review (SLR) and embedded case studies based on secondary data. We develop a conceptual framework that illustrates collective stakeholder orientation emerging from aligned vertical and horizontal stakeholder orientation across the supply chain towards reducing FLW. We explain how achieving such alignment requires these stakeholders to navigate various collaboration conditions (structural and sporadic) that otherwise spur individualism, culminating in FLW mitigation efforts across food supply chains. We develop propositions, motivate future research, and offer practical implications.

我们制定了多种机制，通过这些机制，多方利益相关者可以改善端到端供应链中的粮食损失和浪费（FLW）。在这种情况下，我们将有关利益相关者理论（角色和方向）中供应链上的协作关系的论述整合在一起，并使用多方法方法，将系统文献综述（SLR）与基于辅助数据的嵌入式案例研究相结合。我们开发了一个概念框架，说明了从整个供应链的垂直和水平利益相关者共同取向向减少FLW形成的集体利益相关者取向。我们解释了如何实现这种一致性要求这些利益相关者如何应对各种协作条件（结构性和零星的），否则会激发个人主义，最终导致整个食品供应链中减轻粮食损失与浪费的努力。
