摘　　要：识别横向合并中的单边效应是各国反垄断审查的重点内容。本文通过研究关联价值模型下拍卖或招投标市场上横向合并的单边效应,得出了单边效应产生的充分必要条件,并将差异化产品市场上单边效应的UPP(价格上涨压力测试法)思想推广到拍卖或招投标市场上。在此基础上,利用改进的GUPPI(涨价压力总指数)对甲骨文仁科合并案进行分析,结果与欧美反垄断机构测算出的结果基本一致,即该起合并会产生单边效应。本文提出,GUPPI指数可以作为快速有效的初步筛选工具应用到拍卖或招投标市场中的横向合并审查,中国反垄断执法机构对拍卖或招投标市场中的合并审查可采用类似方法。To identify the unilateral effects of horizontal mergers in the anti-monopoly review is always the key point. This paper characterizes the unilateral effects in auction or bidding markets, and finds a necessary and sufficient condition for the unilateral effects in affiliated value auctions for the first time. It also tries to put the idea of the UPP （Upward Pricing Pressure） test which is used to identify unilateral effects in markets with differentiated products, into the auction or bidding markets. Based on revised GUPPI （Gross Upward Price Pressure Index）, this paper analyzes the case of Oracle--PeopleSoft merger empirically and gets the similar result as antitrust agencies in the U.S. and in the EU that this merger causes the unilateral effects. Being a quick and effective preliminary tool, GUPPI can be used in merger reviews. This paper suggests the antitrust agency in China should apply this kind of method or index in most merger reviews and cases in auction markets.
