Assistance and aiding partners exploited by defectors could be essential to avoid being exploited and expanding the payoff. The research on of human behaviors has suggested that organizations and alliances play an important role in promoting cooperation between humans. Therefore, this article studies the evolution of cooperation in spatial public goods games with alliance strategy on square lattice network where, in addition to the classical strategies of cooperation (C) and defection (D), alliance cooperators (A) are considered as an additional strategy. Alliance players will provide a portion of their payoff to aid their allies in the same group, who have been exploited by defectors. Apparently, alliance players demonstrate a remarkable ability sweep out defectors through network reciprocity. However, by analyzing the parameters, as influenced by cooperators, the cooperation level is a non-monotonic function of aid intensity and synergy factor. The results presented in this article can help to understand the role of alliance strategies, organizations, and taxes in promoting and maintaining cooperation in human society.

被叛逃者利用的援助和帮助伙伴对于避免被利用和扩大收益至关重要。对人类行为的研究表明，组织和联盟在促进人类合作方面发挥着重要作用。因此，本文研究了方格网络上具有联盟策略的空间公共产品博弈合作的演化，其中，除了经典的合作策略（C）和背叛策略（D），联盟合作者（A）被认为是额外的。战略。联盟玩家将提供一部分收益来帮助他们在同一组中被叛逃者利用的盟友。显然，联盟参与者表现出非凡的能力，通过网络互惠扫除叛逃者。但通过参数分析，受合作者的影响，合作水平是援助强度和协同因子的非单调函数。本文提出的结果有助于理解联盟战略、组织和税收在促进和维持人类社会合作方面的作用。
