联合限制竞争行为的主体界定直接关系到相关法律规范的适用。但我国目前对该主体的界定由于缺乏足够的实践而略显理论不足。笔者从主体界定的必要性、行为主体的本质特征与具体形态等方面对主体制度进行了研究,比较分析了欧美国家在该方面的法律规制,并在此基础上对如何界定联合限制竞争行为主体提出了立法建议。 The main body of the joint restricting of competition behavior is directly related to the application of relevant legal norms. However, the current definition of this subject in our country is slightly less theoretical due to lack of adequate practice. The author studies the subject system in terms of the necessity of the subject definition, the essential feature of the subject of action and the concrete form, and compares and analyzes the legal regulation of the countries in Europe and the United States. On this basis, Put forward the legislative proposal.
