认知理性与个体主义方法论的发展

Cognitive Rationality and the Development of Methodological Individualism

通过对个体理性的研究,本文认为,理性既不是完全建构也不是完全演化,而是一种认知意义上的理性。许多诸如行为经济学、文化演化理论和脑神经科学等理论都揭示了理性的认知特征。本文指出,"认知理性"是一个更具有一般性的理性概念,能够调和建构理性和演化理性,充分体现了经济理论与认知科学结合的趋势,能够为经济学提供一个较为一般和经验的理性假设。本文详细探讨认知理性的内涵、外延及其个体偏好、知识、约束和行为等特征,最后进一步讨论"认知理性"对个体主义方法论的发展及其对中国经济学研究的启示。

By the research on individual rationality, the paper considers that rationality is neither complete constructivist nor complete ecological, but has cognitive meanings. Considerable theories such as behavioral economics, cultural evolution theory and neuroscience all disclose the cognitive feature of rationality. We conclude that cognitive rationality is more general concept of rationality, which represents the new theoretic trend of the combination between economics and cognitive sciences, and also can provide a more general and empirical hypothesis for economics. This article also discuss the meaning of cognitive rationality and the features of individual preference, knowledge, constraint and behavior, finally we discuss the development of methodological individualism in the light of cognitive rationality and its enlightenment for Chinese economics research.
