Abstract: Abstract: As a new computer application technology, persuasive technology is widely used in many fields. In the current study, persuasive technology is regarded as the concrete manifestation of the phenomenon of technology mediation in the mediation theory of philosophy of technology, thus the reason why the persuasion result is uncertain can be explained. In the ethical field，in order to deal with the question that persuasive technology may lead to manipulation and paternalism, the framework of inner moral evaluation in the design of persuasive technology is constructed and revised，and the respect for the individual voluntariness is regarded as the starting point of persuasion ethics. In addition, the characteristics of persuasion rationality, the trust in persuasion technology and whether persuasion technology restricts human freedom are discussed.

摘要： 劝导技术作为新型的计算机应用技术被广泛使用于多个领域。在当前的研究中，技术哲学的中介理论将劝导技术看作是技术中介现象的具体表现形式，由此可以解释劝导结果具有不确定性的原因；在伦理层面，应对劝导技术可能导致操纵性与技术家长制等质疑，构建与修正了劝导技术设计中的内在道德评价框架，并将尊重被劝导者的个人意愿看作劝导伦理的起点，此外，对劝导理性的特点、劝导技术的信任问题，以及劝导技术是否限制了人的自由等都进行了讨论。
