- Abstract
- Since the competitive pressure on two-sided O2O platform markets is increasing, new types of competition issues are expected to be raised actively. Due to the indirect network externality, the traditional SSNIP test cannot be directly applied to define the two-sided markets. Therefore, it is necessary to revise the method of market definition by considering the main features of two-sided markets. This paper reviews the existing literature on two-sided market definition and suggests in detail the modified way of market definition for the on-line two-sided transaction platforms with two-part tariff structures. We also discuss the recent issues of market dominance of the on-line two- sided transaction platforms and the operation of competition law in EU, so as to derive implications for enforcement of competition law by the competition authority.
