论“百度竞价排名案”相关市场的法律界定

On the Relevant Market Definition in “Baidu Bidding Ranking Event”

"百度竞价排名案"的判决结果长期备受学界争议,其主要原因之一在于新型互联网经济中存在的双边市场特征,以及内在的不同定价模式和交叉的网络外部效应给双边市场中相关市场的界定带来的挑战。需求替代、供给替代等传统界定相关市场的方法在新型互联网经济条件下遭遇瓶颈,SSNIP测试的适用在互联网双边市场中也有其自身的局限。在涉及网络双边市场滥用市场支配地位的案件中,免费市场支配地位的判断显得更为重要。因此,可以免费市场来考察相关市场竞争状况,以免费市场的份额判断相关网络平台企业是否有支配地位,明确新经济形势下相关市场的界定。

New Internet economy is characterized with bi-lateral markets, and inherently different pricing models and cross-network externalities empose new challenges to the definition of relevant markets. This is why there are lots of disputes in the market definition of the case ＂Tangshan Renren Corp. vs. Baidu Corp. ＂ The traditional alternative analysis and SSNIP methods for rele- vant market definition have met difficulties in internet-based bi-lateral markets. How to effective- ly define the relevant market in Internet bilateral market remains a real problem to be solved. From the consumer or the user＇ s point of view, the judgment of the free market dominance is even more important in cases involving the abuse of the dominant market position in the internet hi-lateral markets. Therefore, we can judge the related market competition status, and determine whether the related network platform enterprise has a dominant position by examining the free- side＇s market share, and eventually clear the problem of defining the relevant market in the new economic situation.
