Abstract:Technological innovation not only promotes the development of the Internet industry,but also impacts the existing competition law system.In the new types of internet unfair competition cases,the party who uses technical means to carry out the competitive behavior usually takes technology neutrality as the defense reason, and claims its own behavior is legitimate.However,from the empirical analysis results of 25 relevant cases,there are also the predicament of whether the technology neutrality defense can be claimed and how to apply the technology neutrality defense.The legitimacy of technology neutrality defense in new types of internet unfair competition cases stems from the three dimensions of “technology, market and law”.The logical premise of applying technology neutrality as the defense is “two neutrality”:technology neutrality and technology provider neutrality.Under this premise,examine the subjective state of the technology provider,and analyze the objective consequences of technology use behavior,so as to determine whether the technology neutrality defense is established.
