跨国并购作为国际直接投资的主要方式，对经济全球化和各国经济发展起到了重要的推动作用。在享受跨国并购带来的利益的同时，不应忽略其可能造成的负面影响。东道国政府对外资并购的规制就是为了尽可能地增加并购的正效应，减少其负效应。不同国家对外资并购有不同的规制方式，其中较常见的就是市场准入规制和反垄断规制。两种规制方式既有区别又有联系，既存在冲突也可以相互协调。根据本国不同经济发展阶段的要求，东道国政府会在两种规制方式中做出有侧重性的选择。长期以来我国吸引外资的态度以鼓励为主，对外资并购的规制更多地采用市场准入规制方式，近年来则逐渐开始加强反垄断规制。但是，毕竟外资并购在我国出现的时间较短，我国对外资并购的规制经验也不足，存在诸多问题和缺陷，造成了某些行业被外资控制的局面。因此，我国可以借鉴国外政府对外资并购规制的成功经验，加强相关理论的研究工作，并在实践中不断完善和健全我国的外资并购规制体制。本文共分七章。第1章是绪论，交待本文的选题背景和选题意义，介绍本文的研究思路和结构、研究方法，并提出本文研究的创新和不足之处。第2章是相关理论研究综述，是本文开展研究的理论背景和基础。首先对外资并购、市场准入规制和反垄断规制的概念做出界定，其中对外资并购的概念界定将以跨国并购概念作为起点。然后对市场准入规制的理论来源和外资并购市场准入规制的相关理论基础做出综述，最后对外资并购反垄断规制的理论基础和实践依据做出介绍和综述，并对国内相关研究做出评述。第3章专门对外资并购的市场准入规制进行理论研究。首先在介绍市场准入规制的实践背景的基础上，建立市场准入规制的基本模型。然后对市场准入规制中的两个主要问题即产业准入范围和外资股权比例限制分别进行理论分析，其中前者将在基本模型的基础上做出分情况讨论，对于后者将建立一个博弈模型对股权比例限制和技术转移之间的关系进行研究。最后分析市场准入规制在不同经济条件下的适用性。第4章专门研究外资并购的反垄断规制。本章将对外资并购中垄断的认定、垄断的来源和传导过程作出详细分析，并研究外资并购如果对东道国市场结构造成影响，据此提出在不同市场结构条件下政府对外资并购进行反垄断规制的政策取向。在本章的结尾，还将对外资并购的市场准入和反垄断规制之间的关系进行讨论，并提出二者之间的协调方法。第5章介绍国外政府对外资并购进行市场准入和反垄断规制的实践经验，每一部分都列举了两个国家作为研究对象，在对不同国家的实践进行分析和对比的基础上，提出对我国的启示。第6章分别对我国外资并购市场准入和反垄断规制的现状做出介绍，并通过对典型案例的分析研究我国对外资并购规制的做法，并提出其中存在的问题和缺陷。第7章在之前介绍国外成功经验和分析我国实践中存在问题的基础上，提出我国外资并购市场准入和反垄断规制的政策取向，并有针对性地提出政策建议。

As the main form of international direct investment (FDI), cross-border merger and acquisition (M&A) play an important role in promoting economic globalization and economic development of countries in the world. We should not ignore the possible negative impact of it while enjoying the benefit of cross-border M&A. The aim of regulations of foreign M&As by the government of host country is increasing the positive effects of M&A while reducing it negative effects. Different countries have different methods of regulation, in which the common ones are market entry regulation and anti-monopoly regulation. There are differences and relations between the two methods which might conflict or coordinate with each other as well. With the requirements of economic development in different stage, the government would made choice by focusing on one of the two methods. For a long run, the attitude of China on attracting foreign capital is mainly encouragement while the main method of regulation of foreign M&As is market access. But in recent years, anti-monopoky regulation is gradually strengthened. After all, it is a short time since foreign M&As entered, China has inadequation in experiences of regulation of forgeign M&A. With problems and defects of regulation, some industries have been controlled by foreign capital. Therefore, China can learn the successful experiences of regulating foreign M&A from other countries strengthen the research on related theories and improve and perfect the system of regulation of foreign M&A. This dissertation is divided into seven parts.Chapter 1 is an introduction which explains the background and significance of the research and introduces the train of research, the structure, research method, innovations and deficiencies of the desertion.Chapter 2 is a review of the theories, which is the theoretical background and foundation of the reseach. First, I will define foreign M&A, market entry regulation and anti-monopoly regulation. The concept of foreign M&A comes from the concept of cross-border M&A. Then, I will review the theoretical source and foundation of market access and anti-monopoly regulation. At last, I will comment on the related researches done by Chinese scholars.Chapter 3 is especially on the theoretical research on the market entry regulation. First, I will establish a basic model of market entry regualion on the basis of introduction on the practice background of market access. Then, I will analyse the industry entry and foreign equity limit, which are the two main issues of market access. First one of them will be disscussesd on the basic model while the latter one will be researched on a game model. Last, I will analyse the applicability of market access in different cenomic condition.Chapter 4 is especially about anti-monopoly regulation. I will analyze the identification, the source and the process of monopoly and research on the effects of foreign M&A on market structure of host country. Then I will propose the anti-monopoly policy on foreign M&A in different market structure. At the end of this chapter, I will disscuss the relationship between market access and anti-monopopoly regulation and the coordination between them.Chapter 5 is the introduction on the experiences of market access and anti-monopoly regulation in foreign country, which include two countries as the object of study in each part. I will analyse and compare the practices in different countries and propose the inspiration of them for China.Chapter 6 is the introduction on the status of market access and anti-monopoly regulation in China. With the analysis of typical case on the practice of regulation in China, the problems and shortcomes could be found.Chapter 7 is suggestion. On the basis of introduction on the experiences of foreign counties and problems of regulation in China, I will put forward policy orientation and pointed suggestions on market access and anti-monopoly regulation of foreign M&A in China.
