摘要
基于电器电子行业,考虑翻新产品竞争及废旧产品可再利用率,构建由制造商与回收处理商组成的闭环供应链,建立无政府政策、财政政策与环境规制政策三种情形下的博弈模型,比较分析三种模型下新产品、翻新产品的产量与价格最优决策,讨论决策及利润与主要参数间的关系。研究表明:产品翻新制造成本存在某一阈值,当制造成本大于阈值上限时翻新产品产量为零,低于阈值下限时翻新产品产量为最大产能,属于三种模型下成本区间的交集时,财政政策下新产品产量更低、翻新产品产量更高,两类产品价格更高。财政政策使制造商利润下降,两种政策均使回收处理商利润增长。
Based on the electrical and electronic industry, considering the competition of refurbished product and renewable rate of waste products, this paper establishes three game models under different situations, there are anarchy policy, government finance and environmental regulation policy, and then, it discusses the optimal decisions of new and refurbished products, and the relationship between optimal strategies and various factors. Results show that, there is a certain threshold for the cost of product refurbishment. When the cost is greater than the upper limit of the threshold, the refurbished product production is zero, and the production is the maximum capacity when the cost is smaller than the lower limit. Besides, the finance policy will reduce new products' production and increase refurbished product production, and the price of two products will increase. The manufacturer's profit will decline under finance policy, and the recycling processor's profit will increase fewer than two policies.

①当(2bξ+b+τ-2)/2=0时,利润函数与产品产量呈线性关系;当(2bξv+b+τ-2)/2>0时,利润函数为凸函数,随着产品产量的增加,利润先降后增;显然(2bξv+b+τ-2)/2<0的情况更符合实际。
