跨国并购是近年来最重要的国际直接投资方式,是国际经济发展的重要推动力量。跨国并购的相关法律问题已经成为理论界研究的重点。但是,在如何界定一项并购行为是否属于跨国并购的问题上,始终存在争议,也因此成为各国国内及国际立法上的一个缺陷。本文从国籍、资本控制及国际影响三种界定国际投资的标准出发,分析了这一问题。 Cross-border M & A is the most important form of international direct investment in recent years and an important driving force for the development of international economy. Relevant legal issues of cross-border M & A have become the focus of theoretical research. However, there is always controversy over how to define whether a M & A activity is a transnational merger or acquisition, and thus it has become a defect in domestic and international legislation of various countries. This article analyzes the problem from three criteria that define international investment: nationality, capital controls and international influence.
