| 内容提要 | 亚当?斯密理论、新古典经济学与博弈论在利己、理性的同一前提条件下，用三种不同的框架研究“经济人”的理性行为，却产生了让三个经济学派完全对立的“囚徒困境”。本文借用经济学边际递减规律条件下无差异曲线的消费模型，界定了经济学语境下的合作、竞争和合竞行为。通过对比分析了亚当?斯密理论、新古典经济学与博弈论“囚徒困境”模型的合作、竞争与合竞行为，探究了三个经济学派研究框架的本质区别以及“囚徒困境”产生的原因。得出的结论是：亚当?斯密理论、新古典经济学和博弈论“囚徒困境” 模型都是在合作与竞争的框架下分析个体的理性行为，但亚当?斯密理论、新古典经济学是在合竞融合（合作与竞争融合）框架下分析个体的理性行为，而博弈论“囚徒困境” 模型在合竞分离（合作与竞争分离）框架下分析个体的理性行为。“囚徒困境”个体理性与集体理性的对立，并不能否定亚当?斯密理论和新古典经济学的结论，囚徒困境并不存在。而经济学家误入“囚徒困境”，则是由于我们没有界定清楚经济学语境下的合作、竞争与合竞行为的区别。 |
| Abstract | In the rational egoism conditions, Adam Smith's theory, Neoclassical economics and Prisoner's Dilemma all Investigate rational behavior of economic man In different frameworks, but the Prisoner's Dilemma lets three economic school opposite. This paper defines the economic context of cooperation, competition and co-opetition behavior based the consumption model of indifference curve under the condition of the law of diminishing marginal returns .Based on model of co-opetition, comparatively analyzes of co-opetition behaviors and competitive behaviors the Adam Smith's theory, new classical economics and Prisoner's Dilemma model, explores the essential difference and reason of opposition in three economic framework of school study. Concluded: Adam Smith theory , New classical economics and Prisoner's Dilemma analyzes rational behavior of individual based on the cooperation-competition framework; Adam Smith theory , New classical economics analyzes rational behavior of individual based on the integration competition and cooperation framework;Prisoner's Dilemma model of Game theory analyzes the rational behavior of individual on the Separation of cooperation and competition framework. Contrast of two kinds of rational results in Prisoner's Dilemma does not negatet the conclusion in Adam Smith's theory and new classical economics. The prisoner's dilemma does not exist. While economists sink into the "prisoner's dilemma", It is due to that we have not clearly defined difference between competition, cooperation and co-opetition behavior in the context of economics. |
