    摘要:

    在碳交易和碳税并行的混合碳政策下,考虑由一个制造商和一个零售商组成的供应链系统,通过Stackelberg博弈方法,构建供应链系统分散决策模型,确定制造商和零售商的最优减排与定价决策,并基于此分析制造商低碳转型过程中的的技术选择策略,探讨低碳产品最优减排率与碳配额和碳税之间的关系,为政府制订政策提供理论依据。研究表明:制造商低碳转型过程中的技术选择主要取决于普通产品与低碳产品碳排放成本的差额,当差额小于阈值时,两种产品共同生产,否则普通产品将被停产;政府可以通过增加碳配额促进低碳产品最优减排率的提升;而碳税对低碳产品最优减排率的影响较为复杂,当减排相对成本较低时,提高碳税可以促进低碳产品减排率的提升,而当减排相对成本较高时,碳税的提高会使减排率呈现先增加后下降的趋势。最后通过算例验证了上述结论。

    Abstract:

    Under the mixed carbon policy of carbon tax and carbon trading, based on the supply chain perspective, this paper studies whether the manufacturer in the process of promoting of clean production technology still need to retain the general technology, and explores the relationship between the optimal reduction rate of the low-carbon product and the carbon quotas and the carbon tax, which provides a theoretical basis for the government to formulate policies. Research shows that whether the manufacturer still retains the general technology depends on the difference between the carbon emission costs of ordinary products and low-carbon products. When the difference is less than the threshold, the two products are jointly produced, otherwise the ordinary products will be discontinued. The government can promote optimal reduction rate of the low carbon product by adding carbon quotas. The impact of carbon tax on the optimal reduction rate is more complex. When the emission reduction cost of clean technology is relatively low, the increase of the carbon tax can promote the reduction rate of low-carbon products. When the cost is high, the increase of a carbon tax will make the emission reduction rate increase first and then decrease. Finally, an example is given to verify the above conclusions.
