摘要
作为一种跨学科的理论框架,演化博弈论广泛应用于生物学和社会科学的研究中。刘闯认为,完整意义上的“博弈”概念在经济学等社会科学的演化博弈论研究中必不可少,但在生物学的科学解释中没有地位;由于演化博弈论所使用的复制子方程与理论生态学中的洛特卡-沃尔泰拉(LV)方程具有数学等价性,生物学中的演化博弈论最好让位于不依赖“博弈”概念的、使用LV方程等工具的演化理论。本文试图论证:无论是在生物学还是在社会科学领域,演化博弈论对“博弈”概念采用的都是同一种技术性的“薄”定义,该定义为演化博弈论提供了一种统一的分析框架;考虑到适用范围和表征能力的差异性,生物学中的演化博弈论不能被使用LV方程等工具的理论所取代。
As an interdisciplinary theoretical framework,evolutionary game theory(EGT)has been widely applied in the study of biology and social sciences.Chuang Liu has argued that the concept of“game”in its full sense is indispensable in the study of EGT in social sciences such as economics,but has no place in scientific explanations in biology;since the replicator equations used in EGT are mathematically equivalent to the LotkaVolterra(LV)equations in theoretical ecology,EGT in biology had better give way to theories that do not rely on the concept of“game”and use tools such as the LV equations.This article argues that,in both biology and social sciences,EGT adopts the same technical“thin”definition of the“game”concept,which provides a unified analytical framework for EGT.Given the differences in scope of application and representational capacity,EGT in biology cannot be replaced by theories using tools such as the LV equations.
