이동통신 시장지배적 사업자의 방송사업자에 대한 M&A가 방송･통신･결합시장에 미치는 후생효과 분석: SKT vs 티브로드 M&A 사례

This study predicted changes in market share due to the merger between SKT and Tbroad and estimated changes in consumer welfare and welfare losses based on empirical data. When SKT, which has market power, merges broadcasters, the market concentration after the merger is increasing in the rest of the market, excluding the mobile communication market and the combined market 1. However, when the combined and number porting effects were applied, the mobile communication and combined markets 1 and 2 were found to converge to the current level of market concentration, but the market concentration of the remaining paid broadcasting market, broadband internet, and combined market 3 rose. As a result, it was confirmed that the market dominance was maintained throughout the broadcasting and communication service market. It can be seen that even if only the basic assumptions of the market share scenario established in this study are applied, the overall market loss in the broadcasting and telecommunications markets can increase. At the point of convergence of services due to the development of broadcasting and communication technologies, regulation on a single market is considered to be meaningless. In other words, in order to establish a smooth competition system, dominant operators need regulation to ease the concentration of market dominance, and it is necessary to promote competition in the broadcasting and telecommunications and combined markets by activating M&A between operators.
