在将路易斯.阿尔文.戴教授的《媒介传播伦理——案例与争论》翻译成中文的过程中,深刻领会了一些他的媒介伦理思想。因此试图从六个方面介绍戴的媒介伦理观:媒介道德的主体,德性论倾向,伦理两难境地,对义务的划分,传播行为道德价值的评价机制,SAD道德推理公式。在此基础上谈了戴的学术成果对中国媒介伦理研究的启示。 During the translation of Luis Alvin Day’s “Media Communication Ethics - Cases and Arguments” into Chinese, he deeply comprehended some of his media ethics thoughts. Therefore, this article attempts to introduce Dai’s media ethics from six aspects: the subject of media ethics, the tendency of virtue, the dilemma of ethics, the division of duties, the evaluation mechanism of moral values ​​of communication, and the SAD moral reasoning formula. On this basis, I talk about the enlightenment of academic achievements of Dai on the research of Chinese media ethics.
