过去的反垄断研究主要集中于政府规制,消费者的作用被长期忽视。本文从中国房地产行业的实际情况出发,提出了新的反垄断理论,认为“消费者价格同盟”的存在和加强可以对垄断厂商起到很大的制约作用,而政府在这一过程中应当转换角色,从规制者转变为信息的提供者或监督者,以实现社会福利最大化或损失较小。 The past antitrust studies mainly focused on government regulation, and the role of consumers was neglected for a long time. Based on the actual situation in China’s real estate industry, this article proposes a new antitrust theory that the existence and strengthening of the “consumer price alliance” can play a very large role in the monopoly of manufacturers, and the government in this process The roles should be changed from regulators to information providers or supervisors in order to maximize or minimize social welfare.
