온라인플랫폼의 관련시장획정에 관한 연구

The main goal of this research is to determine what criteria should be used to define the relevant market for the Internet platform. In order to achieve this goal, this study suggests ways to apply it to domestic law as well as foreign legal research. The platform will be used in various meanings depending on the age, subject, and field, but when viewed from a socio-economic perspective, it refers to a system where various people can base their socio-economic activities. The platform is becoming more important as the business develops over the Internet, and it is predicted that it will continue to expand its range in terms of diversity and accessibility. With the platform as its center, participants are constantly adding new participants to provide, supply, supplement or support goods and services, thereby creating new value and creating a so-called ecosystem. This requires a platform that is easily accessible and stable enough to operate, and the platform must be able to scale and reproduce. In order for such a virtuous cycle structure to be achieved, not only the number of participants in the new platform should increase but also the quality control of the goods and services provided by them should be continuously carried out. The nature of the business based on the Internet platform is that the more platform buyers you acquire, the more commodities and service providers you can acquire, which also leads to more platform buyers. In addition, the platform will pursue economies of scale because the marginal cost required to increase the number of participants is very small compared to the huge cost required to construct it. In addition, once one is stuck in the use of platform business, it may not be easy to transfer to another platform, and competition for preemption of platform participants is fierce. As a result of the platform business, there is a concern that the platform provider will engage in anticom- petitive behavior. Therefore, it is necessary to judge the extent to which the characteristics of the market should be reflected in the competition law enforcement. In order to determine which market operator is subject to competition law, it is necessary to define the relevant market, to be able to evaluate it. Certain types of transactions refer to the fields of transactions in which a competitive relationship or a competitive relationship can be established, and can be classified according to a transaction target, a transaction region, and the like. The commodity-related market deals with whether a commodity or service can be attributed to one specific market with which it is competing with each other. At this time, it examines the inter- changeability of products and services in the marketplace.
