统一碳税和差异化碳税下的再制造绩效评价

分别在无碳税、统一碳税和差异化碳税三种政策下,构建了垄断制造商的利润最大化决策模型,研究实施不同碳税政策对制造商的再制造生产决策、碳排放和社会福利的影响.研究表明:相比于无碳税政策,政府征收碳税减少了制造商的利润和碳排放,在一定条件下有利于提高社会福利;实施碳税政策有利于鼓励更多类型的制造商参与再制造,并且差异化碳税比...

Performance evaluation of remanufacturing strategies under uniform carbon tax and discriminated carbon tax

This paper constructs profit-maximization models for a monopoly manufacturer in three situations,where there are no carbon tax,uniform carbon tax and discriminated carbon tax,respectively.Different carbon tax’s impacts on the manufacture’s optimal remanufacturing production decisions,carbon emission and social welfare are studied.The results indicate that implementing carbon tax reduces the manufacturer’s profit and carbon emission,but increases social welfare in certain conditions.It encourages more manufacturers to adopt remanufacturing.Further,discriminated tax is more flexible than uniform tax.By theoretical comparison and numerical experiment,this paper studies the performance differences of profits,carbon emission and social welfare,after unidirectional and bidirectional tax adjustment on uniform tax.The results show that neither carbon tax is always dominant.The government should choose rational tax adjustment to optimize social welfare according to the characteristics of remanufacture products,unit pollution coefficient,uniform carbon tax level and adjustment range.
