인터넷플랫폼의 간편결제시장으로지배력전이에서 경쟁제한성 쟁점에 대한 일고

Internet platform Mediates distribution of various information. In the case of mediating the distribution of commercial information, a payment service may be provided together for user convenience. These e-commerce transactions are made by convenient method of mobile simple payment. The simple payment service is not profitable in itself, but has the characteristics of a double-sided market that can evolve into a platform that is convenient for users. In providing such a simple payment service, there is a difference in competitiveness between a provider providing only a simple paymevt service and a provider providing a simple settlement service based on an Internet platform. Since Internet platform operators have already secured a large number of users, it is possible to easily distribute their simple payment services to users through a combination with neighboring services. In addition, since Internet platform operators offer different services, they can use price discrimination strategies to offer users more benefits. This phenomenon is the leveraging of market power of the Internet platform market to the simple payment service market. The term "leveraging" itself is neutral, but in fact it is used as a negative vocabulary against fair competition. In this paper, I examine whether the leveraging of market power to the simple settlement service market is illegal under the Monopoly Regulation and Fair Trade Act. The leverage of dominance of the internet platform operator to the simple payment market may be a matter of interfering with business activities during abuse of market dominant position under the Monopoly Regulation and Fair Trade Act. The detailed act that constitutes obstruction of business activity as abuse of market dominant position can be done by way of tying, exclusive dealing, and predatory pricing, but it is confirmed that current law has difficulty in clearly recognizing constitutional requirement. This is due to the fact that it is difficult to judge competition restrictions based on price factors in the Internet platform market. In order to effectively regulate competition in the Internet platform market, it is necessary to establish a criterion for judging competition restriction based on non-price factors.
