互联网市场以免费模式作为普遍的营利方式,并具有技术更新迅速和网络效应显著的特点。针对这些新特点,在确定互联网产品的相关市场时,不宜采用传统的假定垄断者价格测试界定相关技术市场,也不宜草率将相关地域市场界定为全球市场。在互联网经营者市场支配地位的认定上,应对法律规定的各认定因素的重要性进行重新考量:市场份额不再是决定性因素,不应具有推定作用,市场壁垒才是最关键因素。在分析市场壁垒时,要考虑规模经济、用户黏性和知识产权等因素。 The Internet market uses the free model as a general mode of profit, with rapid technological updates and significant network effects. In response to these new features, it is not appropriate to define the relevant technology market by the traditional hypothetical monopolist price test when determining the relevant market for Internet products, nor should it be hasty to define the relevant geographic market as a global market. In determining the market dominance of Internet operators, the importance of each factor identified by law should be reconsidered: Market share is no longer the decisive factor and should not be presumptive. Market barriers are the most crucial factor. In analyzing market barriers, we must consider economies of scale, user stickiness and intellectual property and other factors.
