Abstract
Over the past decade, inequality has become one of the most complex and troubling challenges in the global economy. Many scientists are determined to eliminate inequality to achieve full cooperation. However, our research shows that not all inequalities hinder cooperation. In this article, we study the effects of inequality by introducing the disassortative mixing of the investment amount and enhancement factor assigned to certain individuals in the public goods game. Compared with the traditional version, we find that cooperation can be effectively promoted by aligned inequality, which means that individuals with the highest (lowest) investment capabilities contribute the greatest (lowest) investment amounts. The promotion of cooperation mainly depends on the heterogeneous contribution ability of players. Specifically, cooperators with high contribution ability can maximize collective benefits, causing cooperators with low contribution ability to form compact clusters and resist invasion by defectors. Our research indicates that the diversity of individual endowment and productivity may have a non-negligible influence on the evolution of cooperation among selfish individuals.

不平等对空间演化公共产品博弈的影响
摘要
在过去十年中，不平等已成为全球经济中最复杂和最令人不安的挑战之一。许多科学家决心消除不平等以实现充分合作。然而，我们的研究表明，并非所有的不平等都会阻碍合作。在本文中，我们通过在公共产品博弈中引入分配给某些个人的投资金额和增强因子的非分类混合来研究不平等的影响。与传统版本相比，我们发现对齐不平等可以有效促进合作，这意味着具有最高（最低）投资能力的个人贡献了最大（最低）的投资金额。合作的推进主要取决于玩家的异质贡献能力。具体来说，贡献能力高的合作者可以最大化集体利益，使贡献能力低的合作者形成紧密的集群，抵抗叛逃者的入侵。我们的研究表明，个体禀赋和生产力的多样性可能对自私个体之间的合作演变产生不可忽视的影响。
