明确经营者集中的控制权变化有着重要的意义，它不仅有利于合并申报当事人明确申报义务，同时方便反垄断执法机构对交易进行审查。欧盟《合并控制条例》中所涉及的控制是指对一家或者多家企业行使决定性影响的可能性，包括以股票或者资产、合同、专利使用权转让和特许权协议、经济联系等方法实施的单独或者共同的控制。我国现行《反垄断法》第20条也提出了取得控制权和施加决定性影响两种认定经营者集中的方法。有鉴于此，探究欧盟《合并控制条例》中的控制权制度对发展和完善我国《反垄断法》中的控制权和决定性影响制度有着重要的理论和实践意义。
Clarification of changes of control relating to concentrations of undertakings is of great importance for helping the merger parties perform their notification duties and the antitrust regulators review a transaction. Control refers to the possibility of exercising decisive influence over an undertaking. It covers sole control and joint control resulting from the acquisition of shares or assets，contracts，licensing and franchising agreements and economic relationships，etc. Article 20 of Chinese Antimonopoly law contains somewhat ambiguous language concerning right of control and decisive influence. Since Chinese Antimonopoly Law largely follows the model of EU and German competition law，the depth analysis of control issues in the EU merger control system can develop effective merger control system in China.
