作为经济伦理逻辑起点的“经济人”概念是对于传统主流经济学理论中“经济人”概念的移用。但是,这一作为逻辑起点的概念在经济伦理的理论推演以及社会实践中都遇到了难以克服的困难,陷入了困境。“囚徒困境”表达了“经济人”概念基础上的集体理性与个人理性的内在困境。必须重新审视“经济人”的概念,将个人对好生活的全面理解与个人作为社会责任、义务的承担者的观念引进经济伦理的讨论。

As a logical starting point of the economic ethics concept, "economic homo" is a transfer of the same concept from traditional mainstream economic theories. In theoretical inference and social practice of economic ethics, however, the concept of economic homo has met with formidable difficulties, and has been caught in a dilemma. The "prisoner dilemma" shows the internal difficulties of both collective and individual rationality based on the concept of economic homo. The concept needs to be reconsidered and the concept of an individual's full understanding of good life combined with individual as a social responsibility and obligation holder needs to be introduced into the discussion of economic ethics.
