摘　　要：不同环境质量产品的替代和厂商间的策略反应会影响环境政策预期目标的实现.通过构建一个纵向产品差异化模型,研究了存在消费者环境偏好和产品环境质量差异的寡头竞争市场中,环境政策对产品环境质量差异程度、产业污染排放以及社会福利的影响.结果表明,产业污染排放标准可以提高产品环境质量,减少产业总污染排放,提高社会福利;而对污染型产品收费则会降低产品的环境质量,增加产业污染排放,降低社会福利.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 influence of some environmental policy on product environmental quality, industrial aggregate emission and social welfare was discussed. The results show that unit emission can reduce industrial emission, improve product environmental quality and social welfare; while product charge will decrease product quality, increase industrial aggregation emission and reduce social welfare.
