垄断带来效率损失的政府管制研究

Government Regulation on Efficiency Loss by Monopoly

本文认为,垄断带来效率损失的理论基础是垄断者拥有垄断势力,而垄断势力的结果是较高的价格和较低的产量,价格与边际成本间的差距带来了社会成本,导致了社会福利损失。通过模型分析,我们可以看到政府对垄断产品价格进行管制以克服低效率、降低无谓损失,提高资源的配置效率的过程。基于这一分析,本文提出,针对我国的具体情况,对不同的垄断分类,政府管制的方式和手段应有所不同。

Monopoly brings low efficiency and vast social cost. The monopoly＇ s force is the base of above. Monopoly can result in high price and low output, and because of social cost which takes by the difference between price and marginal cost, it will result in the social welfare loss. Through the model analysis, we can see such a course that the government carries out price regulation on monopoly products to conquer low efficiency, reduce needless loss, and improve the efficiency of using resources. On the basis of this theory, the text suggests from our country actuality and different sorts of monopoly, the regulation＇ s mode and measure should have diversity.
