With the increasing autonomy of artificial intelligence,the problem of attribution of moral responsibility in artificial intelligence appears.The monism of responsible subject holds that humans should bear all moral respon-sibility;the dualism of responsible subject holds that moral responsibility should be shared by humans and artificial intelligence;the self-responsibility theory of artificial intelligence,based on the future that artificial intelligence can develop,holds that as an entity with intelligence and autonomous decision-making ability,the problem of moral responsibility generated by artificial intelligence should be attributed to artificial intelligence itself.The es-sence of the three kinds of arguments is the different understanding of the concept of moral responsibility itself,so there is a dispute about the objects of moral responsibility imputation.From the perspective of practice,Strawson believes that the problem in the attribution of moral responsibility should be developed on the expression of"reac-tive attitudes".Based on Strawson's reactive attitudes theory,this paper analyzes the problem of responsibility at-tribution in artificial intelligence and makes the problem in the attribution of moral responsibility more clearly.Arti-ficial intelligence can only be treated as an object of"objective attitudes"and is not seen as a bearer of moral re-sponsibility.Humans,as developers,managers and users of artificial intelligence,are regarded as the object of"reactive attitudes"and will bear the full moral responsibility.
