Abstract: In order to solve the problem of the influence of uncertain quantity of recycled products on fiscal intervention policy and pricing decision in double competitive closed-loop supply chain, a pricing decision model of double competitive closed-loop supply chain with uncertain quantity of recycled products is constructed by using game theory and MATLAB numerical simulation method. It is analyzed and verified from four dimensions that uncertain quantity of recycled products affects competition intensity, sales and pricing decision of closed-loop supply chain. The research results show that when the quantity of recycled products fluctuates greatly, the recycling price and repurchase price of recyclers and remanufacturers show an increasing trend. In closed-loop supply chain, the profit of recyclers, retailers and social welfare show an increasing trend, but the profit of manufacturers decreases, i.e., returns. Uncertainty of receipt quantity directly affects the enthusiasm of manufacturers who play a leading role in closed-loop supply chain to implement remanufacturing.

Key words: closed-loop supply chain, double competition, uncertainty, fiscal intervention, pricing decision

摘要： 为解决双重竞争闭环供应链中回收产品数量不确定对财政干预政策及定价决策影响的问题，运用博弈论和Matlab数值仿真的方法，构建回收产品数量不确定的双重竞争闭环供应链定价决策模型，从4个维度剖析并验证回收产品数量不确定对闭环供应链竞争强度、销售及回收价格、供应链节点企业利润及社会福利、回收率的影响规律，研究结果表明：当回收产品数量波动较大，回收商和再制造商的回收价格及回购价格呈现增加的趋势；闭环供链中回收商利润、销售商利润以及社会福利呈现增加的趋势，但是制造商利润下降，即回收数量不确定直接影响闭环供链中起主导作用的制造商执行再制造的积极性。
