我国自改革开放以来,经济高速发展,逐渐实行了社会主义市场经济制度。市场经济的本质特征是竞争,没有竞争的市场算不上市场经济。但是市场经济中的竞争和垄断是如影随形、相生相伴的。特别是随着市场化程度的不断提高,各种垄断现象也日渐明显。企业联合限制竞争、优势企业滥用支配地位、或者通过合并试图垄断市场等行为,都阻碍了统一、开放、竞争的市场的形成,影响了国民经济的快速发展,有效规范竞争秩序已成为当务之急。本文将从滥用市场经济支配地位的定义、分类、对其进行规制的必要性进行阐述,并提出我国在这方面的不足和完善建议。 Since the reform and opening up, China has witnessed rapid economic growth and gradually implemented the socialist market economic system. The essential feature of market economy is competition, and the market without competition is not market economy. However, the competition and monopolization in the market economy are complicated and complicated with each other. In particular, with the continuous improvement of the degree of marketization, various monopolies have become increasingly apparent. The combination of restriction of enterprises, the abuse of dominance by dominant enterprises or the attempt to monopolize markets through mergers have hindered the formation of a unified, open and competitive market, affected the rapid development of the national economy and effectively regulated the order of competition. This article will elaborate from the definition of abuse of market dominance, classification, and the need to regulate them, and put forward our country’s inadequate and perfect suggestions in this regard.
