经济学假定行为主体是自利主义者,经济主体之间的关系建立在各自利益驱动的基础上,由此拓展而形成错综复杂的社会关系。囚徒困境、公地悲剧等经典理论论述了“不合作”的存在基础。为解释社会上存在的合作行为,诸多学科和领域给出了不同的解释。本文通过对博弈论、信任理论、演化理论、生物学、社会学等多学科的相关理论的分析,对关于“合作产生”的理论进行综合,并进行一定程度的总结,期望对现有的关于合作产生的解释提供更为坚实、全面的分析,并指出进一步研究的可能方向。 Economics assumes that the main body of behavior is an egalitarian, and the relations among the economic subjects are based on their respective interests and thus expand to form intricate social relations. Prisoner’s dilemma, the tragedy of the commons and other classical theories discuss the existence foundation of “non-cooperation”. To explain the existence of cooperative behavior in society, many disciplines and fields give different explanations. Through the analysis of theories related to multidisciplinary such as game theory, trust theory, evolutionary theory, biology and sociology, this dissertation synthesizes the theories about “cooperation ” and summarizes to a certain degree, Provide a more solid and comprehensive analysis of the explanations of cooperation and point out the possible directions for further research.
