摘要: 基于手工收集的上市公司受到反垄断执法的数据库,本文采用事件研究法,考察了股票市场对反垄断执法的反应,为中国反垄断执法的惩戒效应提供了初步证据。具体地,本文发现,在反垄断立案调查和处罚决定事件附近,市场均产生显著的负反应,被执法企业的市值损失达到11.5%。在一些垄断违法的典型行业,市场负反应还会溢出到整个行业,说明反垄断执法不仅惩罚了违法企业,还能有力地威慑整个垄断行业。进一步分析市场反应的异质性表明,市场反应的大小除了能被直接违法成本、垄断利润调整成本和市场信号机制解释外,在中国独特的反垄断执法制度背景下,违法企业的央企性质、执法机构类型、违法信息公开及时程度,同样会影响市场反应大小。本文的结论对评价中国反垄断执法成效、指导反垄断立法和执法机构改革均具有重要意义。

Abstract: Based on hand collected listed-company antitrust enforcement database, this paper uses event study to investigate response of stock market on antitrust enforcement, and provides primary evidence for the disciplinary effects of Chinese antitrust enforcement. Specifically, this paper finds that the market reacts negatively toward a company that will receive or already received antitrust investigation or final penalty, and the company will suffer a 11.5% loss of market value. In typical infringing industries, negative reaction will spill over to the whole industry, indicating that antitrust enforcement not only punishes infringing firms, but also effectively deters the whole monopoly industry. Further analysis on the heterogeneity of market reactions reveals that the strength of market recaction can be explained by direct law-breaking cost, readjustment cost of monopoly profit and market signal effect, and under China’s unique institutional background of antitrust enforcement, the strength of market reaction will also be affected by the nature of companie as central CEOs, type of enforcement agent and timeliness in release of infringement information. These results are of great significance for evaluating the achievements of antitrust enforcement in China, as well as for guiding the reform of antitrust legislation and enforcement agencies.
