摘　　要：为研究碳排放权抵消机制对制造/再制造生产决策的影响,分别构建基于配额和基于排放量两种抵消机制的生产决策优化模型。分析抵消上限、再制造品接受度对产量、企业利润、消费者剩余和社会总福利的影响。结果表明,抵消机制会提高新品产量并降低再制造品产量,增加企业利润、消费者剩余和社会总福利,以上变化幅度随抵消上限的提高先增大后减小。再制造品接受度较高时,最优解对抵消上限变化更敏感。政府应将抵消上限设定在低水平且谨慎调整,可通过适度牺牲企业利润提高社会福利。拥有高配额的企业在配额机制下运作更具效益,反之在排放量机制下更优。Carbon offset mechanism is an important supplementary regulation of carbon market.To study the impact of carbon offset mechanism on manufacturing/remanufacturing production decisions,two production decisions models are constructed respectively for emission-based and allowance-based carbon offsets mechanism.Through model solving and numerical analysis,the optimal decisions under the two models are compared to explore the impact of offset cap,and acceptance of remanufactured products on optimal production decisions.The results show that,the offset mechanism will increase the quantity of new products and reduce the quantity of remanufactured ones,and improve the firm's profit,consumer surplus and social welfare.Raising offset cap will strengthen this trend.However,an increase in the offset cap does not always reduce the cost of carbon emissions.This trend reverses when offset cap is too high.Optimal strategies are more sensitive to offset cap when the acceptance of remanufactured products is large.For government,a reasonable offset cap should be set to improve social welfare,although this may reduce the firm's profit.Manufacturers with high free allowance can earn more profit under allowance-based mechanism than that under emission-based mechanism,and vice versa.
