Sophistication of Antitrust Merger Review

随着全球经济的发展，并购和其他公司活动已变得相当全球化。在这种国际趋势的背景下，日本的合并监管存在哪些问题？确定这些问题是本研究所要解决的挑战。由于某些类型的公司战略，如合并，对竞争的影响往往只能在认真、逐案分析之后才能加以评估，因此必须进行审慎的审查，以确保有利于竞争、提高效率的合并不会在可能的反垄断执法的威胁下受到抑制。我们必须避免这种假阳性的规定。有鉴于此，本研究对企业合并规制进行了法律的分析和经济分析，以期对实际的企业合并案例的审查有所帮助。

With the global development of economies, M&A and other corporate activities have become considerably global in nature. Against the background of this international trend, what problems exist concerning the merger regulation in Japan. The identification of such problems was the challenge this study addressed. Because the competitive impacts of certain type of corporate strategies such as mergers can often be evaluated only after careful, case-by-case analysis, deliberate review must be undertaken to ensure that pro-competitive, efficiency enhancing mergers are not chilled under the threat of possible antimonopoly law enforcement. We must avoid such kind false positive regulations. In light of this, this research undertook a legal and economic analysis in merger regulation in order to sophisticate actual merger case review.
