Post-merger integration governance and management mechanisms facilitating lateral collaboration remain opaque. In an analysis of the Renault-Nissan Alliance, we abduce a theory of equity-trust by drawing on microfoundations theory and four types of organizational justice. We identify five practices that motivate distributive, procedural, informational, and interactional justice, and find that these practices discourage opportunistic behavior and foster trust thereby influencing alliance performance in two ways: sum of the parts and learning and synergies. Our findings contribute to understanding cross-national lateral collaboration in the form of symbiotic post-merger integration in strategic alliances.

促进横向合作的合并后整合治理和管理机制仍然不透明。在对雷诺-日产联盟的分析中，我们通过借鉴微观基础理论和四种类型的组织正义来推导出股权-信任理论。我们确定了促进分配正义、程序正义、信息正义和互动正义的五种做法，并发现这些做法会阻止机会主义行为并促进信任，从而以两种方式影响联盟绩效：部分总和以及学习和协同作用。我们的研究结果有助于理解以战略联盟中的共生合并后整合形式存在的跨国横向合作。
