计量工具在横向兼并反垄断审查中的应用——以美国Staple-Office Depot合并案为例

Measuring Tool Application in Horizontal Merger Anti-monopoly Review ——A Case Study of American Staple-Office Depot Merger

计量经济学的产生与发展使经济学由定性分析走向定量分析,在反垄断执法中企业是否滥用市场支配地位、经营者集中审查等内容都离不开计量工具的支持。反垄断部门在对企业横向兼并进行审查控制时包括了定义相关市场的定义、评估兼并的价格效应和预测兼并可能带来的效率改进,其中所进行的每一步都会运用到计量经济学。文章对计量工具在反垄断审查中的应用进行归纳总结,取其一点以案例法强调计量工具的应用。以美国Staples-Office Depot合并案为例,介绍计量方法在横向兼并审查控制中的具体运用,总结得出中国反垄断执法需要在数据收集、人才培养、案例研究等方面继续加强。

Econometrics has led economics from quality prise is abusing market dominant position and to investigate analysis to quantity analysis. To determine if the enter- the managers collectively both rely on the econometric methods.

At last, the paper points out that China should strengthen data collection, personal training and case studying for the enforcement of anti-monopoly law.
