英文摘要：
  Income redistribution is the transfer of income from some individuals to others directly or indirectly by means of social mechanisms, such as taxation, public services and so on. Employing a spatial public goods game, we study the influence of income redistribution on the evolution of cooperation. Two kinds of evolutionary models are constructed, which describe local and global redistribution of income respectively. In the local model, players have to pay part of their income after each PGG and the accumulated income is redistributed to the members. While in the global model, all the players pay part of their income after engaging in all the local PGGs, which are centered on himself and his nearest neighbours, and the accumulated income is redistributed to the whole population. We show that the cooperation prospers significantly with increasing income expenditure proportion in the local redistribution of income, while in the global model the situation is opposite. Furthermore, the cooperation drops dramatically from the maximum curvature point of income expenditure proportion. In particular, the intermediate critical points are closely related to the renormalized enhancement factors.

中文摘要：
收入再分配是指通过税收、公共服务等社会机制，将收入从一部分个人直接或间接地转移给另一部分人。利用空间公共物品博弈，我们研究了收入再分配对合作演化的影响。构建了两类分别描述收入局部再分配和全球再分配的演化模型。在本地模式中，玩家必须在每次PGG后支付部分收入，并将累积收入重新分配给成员。而在全球模式中，所有参与者在参与所有以自己和近邻为中心的本地PGG后，都会支付部分收入，而累积的收入会重新分配给全体人口。我们发现，随着收入支出在地方收入再分配中所占比例的增加，合作显著繁荣，而在全球模型中，情况恰恰相反。此外，合作从收入支出比例的最大曲率点急剧下降。特别是，中间临界点与重整化增强因子密切相关。
