本文通过对过失相抵的构成要件分析,得出不存在认定过失相抵的特殊条件,过失相抵不过是过错责任原则在受害人身上运用的结果。受害人无过错,其行为符合侵权法上无过错责任的认定条件时,也会产生适用过失相抵责任相同的结果。过失相抵实质上是受害人责任的体现,应当在受害人的行为符合侵权行为构成要件时,对自己的行为承担责任,在受害人无过错时,也会因此而导致侵权人责任的减轻。 Through the analysis of the compositional elements of the negligence, this paper concludes that there are no special conditions for determining the negligence of negligence, but the negligence of negligence is only the result of the fault liability principle applied to the victim. When the victim is at fault and in conformity with the conditions for the determination of faultless liability in the law of tort, the same result may apply to the application of the fault of negligence. The negligence is essentially the manifestation of the victim’s responsibility. When the victim’s behavior complies with the elements of the infringement, he / she should be responsible for his or her own behavior. If the victim is at fault, the responsibility of the infringer will be lessened.
