在经济伦理学的论域内 ,“交易”被赋予了经济学与伦理学的双重理解。作为一种利益的市场交换行为 ,效率与正义共同构成了市场交易的完备正当合理性意义。因此 ,作为“社会互动形式”的市场交易 ,不仅有其内在的道德正当性证明 ,也有其外在的伦理规范性限度。 In the field of economic ethics, “transaction” is given a dual understanding of economics and ethics. As a kind of interest market exchange behavior, efficiency and justice together constitute the complete legitimacy significance of market transactions. Therefore, the market transaction as “the form of social interaction” not only has its inherent proof of moral legitimacy, but also has its external limits of ethical norms.
