摘　　要：本文采用2002-2008年18个一线城市家电零售企业层面的数据,对家电零售行业市场结构与利润的关系进行了研究。结果表明,我国家电零售行业市场份额和市场集中度对利润率的影响都比较微弱,无论是基于合谋的SCP假说还是基于单方面效应的相对市场势力假说都不成立。而X-效率变量既与利润率呈显著正相关,又与市场份额呈显著正相关,因此相对于其他三种假说,X-效率结构假说对家电零售行业市场结构-利润关系更有一定程度的解释力。由于国美对永乐、大中的并购既没有提升利润,也没有增加市场势力,所以不应采取过分严厉的反垄断并购政策。Based on the analysis of the data of electrical appliance retailers in 18 firsttier cities from 2002 to 2008, this paper makes a preliminary research into the relationship between electrical appliance retailers＇ profit and market structure. The results indicate that the measure of the electrical appliance market share and concentration can hardly pose influence on its retailers＇ profit. Thus both hypotheses of SCP based on conspiracy and relative market power based on unilateral effect are invalid. However, variable of X efficiency carries a positive relation with both profit margin and market share. Compared with three other hypotheses, the hypothesis of Xefficiency structure is more feasible to expound the relationship between the electrical appliance market structure and its profit. The paper argues that there is no profit growth or market power reinforcement regarding to the Gome＇s merger with Yolo and Dazhong, so it is not necessary to implement the more strict antimonopoly policy on merger.
