对近两年一种比较为人所接受的观点 ,即“经济学已经完全摆脱了道德判断和道德说教” ,本文提出了不同看法。文章认为 :经济学不做道德评价的说法不能成立 ,没有功利主义道德观 ,就根本不可能有称之为经济学的东西 ;从新制度学兴起之日起 ,道德问题就逐渐纳入经济学的研究范围 ;经济学并不直接地或主要地研究道德规范 ,但它总是给社会道德规范的变化以巨大的影响 ;承认经济学受到道德观的制约 ,承认经济学有观念的倾向性 ,这一点也不会影响它的科学性 In the past two years, a more accepted view is that “economics has completely got rid of moral judgments and moral preaching.” This article presents different views. The article holds the view that economics can not hold the view that moral evaluation is not done and there is no utilitarian moral concept that can not be called economic at all. From the date of the rise of New Institutional Theory, moral issues are gradually incorporated into the study of economics Range; economics does not directly or mainly study moral norms, but it always has a huge impact on changes in social ethics; acknowledges that economics is constrained by moral values ​​and acknowledges the notion of propensity for economics It will not affect its scientific nature
