| The petroleum industry is the pillar of the national economy. The health and the efficiency of China's petroleum market are directly related to the sustainable and high-speed development of the national economy. However, the structure of China's petroleum market is highly monopolized by three oligarchs, CNPC, SINOPEC, and CNOOC for a long time, which is a great challenge to the order of competition. Especially in recent years, with the accession to the WTO, the domestic market is opening up gradually. Furthermore, as the risen tendency towards the international oil price is more obvious and the behaviors of the domestic oligarch enterprise that disregards the social responsibility for self-interest are more common, the voice of the community to regulate the monopoly of the petroleum industry is becoming louder. The promulgation of Anti-monopoly Law in 2008 was once regarded as a sword to break the monopoly situation of the petroleum industry, but practically there are many limitations for this new law. Therefore, how to perfect Anti-monopoly Law in order to regulate the petroleum industry effectively has become the key problem to establish its central place in our socialist marketing economy.Based on the reasons above, the thesis is designed to give some advices for perfecting Anti-monopoly Law. First of all, the thesis has expounded the theory and practical significance of the research and selected the suitable method. Secondly, the thesis has investigated the history and the properties of the monopoly and particularized the behaviors of the oligarch enterprise with Anti-monopoly Law. At last, necessity and limitations of the law are mentioned and the experiences abroad are compared with each other in order to put forward some suggestions. |
