最近的研究表明，合作行为的出现可以用广义互惠来解释，这是一种基于“被别人帮助就帮助别人”原则的行为机制。在复杂系统中，合作动力学很大程度上取决于网络结构，而网络结构决定了相邻个体之间的相互作用。这些相互作用通常表现出多维特征，要么是不同类型的关系，要么是时间动态，这两者都可以建模为“多路”网络。在此背景下，本文以多维网络社会为背景，对广义互惠激励下的合作模式进行研究。我们的研究结果表明，多元网络结构可以增强广义互惠在促进合作中的作用，其中一些网络维度作为其他网络维度的潜在支持。因此，广义互惠迫使个体的合作贡献集中在最有利于合作存在的维度上。
Recent studies suggest that the emergence of cooperative behavior can be explained bygeneralized reciprocity, a behavioral mechanism based on the principle of “help anyone if helped by someone”. In complex systems, the cooperative dynamics is largely determined by the network structure which dictates the interactions among neighboring individuals. These interactions often exhibit multidimensional features, either as relationships of different types or temporal dynamics, both of which may be modeled as a “multiplex” network. Against this background, here we advance the research on cooperation models inspired by generalized reciprocity by considering a multidimensional networked society. Our results reveal that a multiplex network structure may enhance the role of generalized reciprocity in promoting cooperation, whereby some of the network dimensions act as a latent support for the others. As a result, generalized reciprocity forces the cooperative contributions of the individuals to concentrate in the dimension which is most favorable for the existence of cooperation.
