平台垄断、劣币现象与信息监管——基于搜索引擎市场的研究
Platform Monopoly,Gresham's Law and Information Regulation—Based on the Search Engine Market
摘要
Abstract
As the entrance of internet,the searching platform acts as the" visible hand" between the supply and demand of information,however,the problem of false information behind the prosperity of platform economy are also widely criticized. This paper analyzes the process of dynamic evolution of Chinese search market, studies the interactive mechanism between the search platform, users and advertisers based on the two-sided market model embedded in the advertising market and the commodity market.The research shows that the user's limited cognition, the platform's information superiority and the loose external supervision are the condition of the market failure.There is a trade-off between self-profit and the information quality for a non-neutral search platform,and the inclusion of false information may lead to Gresham's Law. At this point, the appropriate external supervision is a positive constraint on advertising behavior of platforms. Protecting the effective platform competition mechanism and establishing appropriate disciplinary measures are important ways to reduce false information,protect the platform and users' fair status and build a healthy market environment.关键词
