三级价格歧视与政府排污权配额初始定价问题研究

Research on Third-degree Price Discrimination and Initial Pricing of Government's Pollution-discharge Right Quota

三级价格歧视理论广泛应用于市场经济的各个领域,文章探讨了政府依据三级价格歧视对排污权配额进行初始定价的可行性及分配方式,分析了政府依据三级价格歧视对排污权配额初始定价所带来的社会经济福利影响,并给出了增进社会经济福利水平的定价条件,即政府在控制排污权总量水平下,对需求弹性大的行业制定低价所引起的对配额的增加量一定要大于对需求弹性小的行业制定高价所引起的对配额的减少量。

The third--degree price discrimination theory is widely applied in various fields of market economy. This paper discusses the feasibility to set an initial price for pollution-discharge right quota and its allocation mode for the government according to the third-degree price discrimination theory, and then analyzes its impact on social economic benefits. The research suggests a price level that is able to increase the social economic benefits. On the premise that the government controls the aggregate level of poUution-diseharge, the increase of quota by high demand elasticity industry must be greater than the reduction of quota by low demand elasticity industry.
