论经济理论的理性基础及回归知识分布的有限理性

完全理性是经济学的一个重要假设,与人类知识的进展相关,知识的进展强化了人类对理性的认知。有限理性提出以来,完全理性假设既受到挑战又与有限理性共生于经济理论之中,如何使两者有机地统一起来,对于经济学理论的发展具有重要意义。本文将知识分为关于自然的知识和关于人类自组织的知识两个方面,引证出理性主要由人类自组织的知识通过模式化认知构建,并通过对人的生物性价值认知模式的研究,提出有限理性在于知识的有限性,而完全理性也在于知识的不断扩展,使经济理论理性假设归结到知识。

Complete rationality is an important hypothesis of economics, and it is related to the progress of human knowledge, and the progress of knowledge strengthens the human＇s cognition to the rationality. After bounded rationality has been put forward, the complete rationality hypothesis is challenged and born with bounded rationality in economic theory. How to make both organically unified has an important significance for the development of economic theory. The paper introduces knowledge about nature and about human, and cites the rationality is constructed mainly by knowledge of human self organization through the cognitive model. In addition, based on the studies on the cognitive model of human biological value, it puts forward the bounded rationality lies in knowledge limitation, and complete rationality lies in continuous knowledge expan- sion so that the rationality assumption of the economic theory can be ascribed to knowledge.
