| As we know, market-directed economy is competitive and it's ruled with law, so the legislation and enforcement of antimonopoly law is one of the most important tache in establishing socialistic market-directed economy system. Antimonopoly law is devoted to restore free competition. It's in favour of economizing resource and generating efficient market-directed economy running. So our country has quickened its pace of legislating antimonopoly law.The basic principle of antimonopoly law is the spirit, general guiding idea, and the embodiment both of value orientation and legislative tenet of the antimonopoly law. The basic principle of antimonopoly law is the junction of its rule and value. The uncertainty of the antimonopoly law may result in unjust, so principle is called for making up for justice.According to our basic national conditions, the uncertainty of the rule of antimonopoly law, the change in our economic policy and the foreign legislation's experience, I conclude that there're two most important basic principles, that is, rationalization and efficiency in accordance with just. The principle of rationalization is used to notarize whether any behaviour or situation is illegitimate. It needs comprehensive analysis. The other principle means the law must have efficiency, meanwhile, it should be accord with just. They're based on the value of economic democracy, economic freedom and competitive order. However, these principles are not absolutely abstract, they're also embodied in concrete systems, such as illegal cognizance system, report and register system, exception of application system and executable system. |
