The indirect reciprocity theory suggested that the cues of reputational consequences determine the scope of indirect reciprocity and influence whether individuals decide to interact with others regardless of group identity. However, in more complex intergroup environments, there is no clear answer as to how indirect reciprocity guides intergroup cooperation. Based on this, the study used Intergroup Parochial and Universal-Cooperation (IPUC) to construct in-group interaction scenarios and explore the influence of reputation on different cooperative behaviors from both individual and group perspectives. The study found: (1) at the individual level, the influence of personal reputation on different cooperative behaviors is limited by group identity, and ingroup favoritism always exists, supporting the viewpoint of Bounded Generalized Reciprocity; (2) at the group level, group reputation promotes universal cooperation and suppresses parochial cooperation, regardless of group type, consistent with the Unbounded Indirect Reciprocity. The study supported and extended indirect reciprocity theory, providing a reference for understanding group relations.

动态间接互惠：嵌套社会困境中个人声誉和群体声誉对合作行为的影响

间接互惠理论认为，声誉后果的线索决定了间接互惠的范围，并影响个人是否决定与他人互动，而不管群体身份如何。然而，在更复杂的群体间环境中，间接互惠如何指导群体间合作还没有明确的答案。基于此，本研究利用群体间狭隘与普遍合作（IPUC）构建群体内互动场景，从个体和群体的角度探讨声誉对不同合作行为的影响。研究发现：（1）在个体层面，个人声誉对不同合作行为的影响受到群体认同的限制，群体内偏袒始终存在，支持了有界广义互惠的观点；（2）在群体层面，无论群体类型如何，群体声誉都会促进普遍合作并抑制狭隘合作，这与无界间接互惠一致。该研究支持并扩展了间接互惠理论，为理解群体关系提供了参考。
