Self-preference is an important form of cross-market expansion for digital platforms.The self-preference of digital platforms itself is not illegal.When analyzing whether the self-preference of digital platforms is illegal,we should focus on whether the platform implementing self-preference has dominant market position,the dependence of the favored market on the platform implementing self-preference,and whether the self-preference harms competition.Based on the above analytical el-ements,this paper conducts a case study on the self-preferential behavior of search engine platforms and the possible anti-competitive effects,according to which it puts forward policy recommendations to improve China's anti-monopoly legislation and law enforcement.
