The Impact of Moral Information on Cooperative Behavior—The Mediating Role of Common Ingroup Identity

本研究采用群际狭隘与普遍合作范式(IPUC)，通过实验法探讨道德信息对合作行为的影响及其作用机制。结果发现：在嵌套社会困境中，积极的道德信息能够促进普遍合作，减少强狭隘合作。与此同时，积极道德信息还可以通过增强共同内群体认同促进普遍合作。本研究对于增进群际合作、实现互惠共赢具有一定的理论和实践价值。This study adopts the Intergroup Parochial and Universal Cooperation Paradigm (IPUC) to explore the impact and mechanism of moral information on cooperative behavior through experimental methods. The results showed that in nested social dilemmas, positive moral information can promote universal cooperation and reduce strong narrow cooperation. At the same time, moral information can also influence universal cooperation through common ingroup identity. This study has certain theoretical and practical value for enhancing intergroup cooperation and achieving mutual benefit and win-win outcomes.
