差异化竞争与产品排放标准效应分析

Analysis of Differential Firm Competitive and Effects of Unit Emission Standards

通过建立纵向差异化模型,研究了寡头竞争市场中,当消费者对产品环境质量具有不同偏好,差异化厂商进行产量竞争和价格竞争时,产品排放标准对产品环境质量、产业总污染排放以及社会福利的影响。结果表明,厂商进行产量竞争时,产品排放标准可以提高产品质量,减少产业污染排放,提高社会福利;厂商进行价格竞争时,产品排放标准可以提高产品质量,增加产业污染排放,减少社会福利。

In a vertical product differentiation model, under the condition of consumer differ in their environmental preference and the coexistence of substitute products with different environmental impacts, the effects of unit emission standards on product environmental quality, industrial aggregate emission and social welfare is discussed, when the firms behave in quantity and price competitive. The results show that can under Cournot condition, unit emission standards can reduce industrial emission, improve product environmental quality and social welfare; while under Bertrand condition, unit emission standards will increase industrial emission, reduce product environmental quality and social welfare.
