政府补贴下制造/再制造竞争机理研究

以政府“以旧换再”补贴政策为背景,建立了原始制造商、再制造商与零售商两阶段博弈模型.基于此博弈模型,考虑政府不采取补贴政策、政府补贴给再制造商及政府通过零售商补贴购买再制造产品消费者3种情况,对比分析了政府不同补贴策略对两种产品单位批发价格、零售价格、销售量、利润、消费者剩余及环境的影响.结果表明:当再制造产品的需求不受废旧产品回收量限制,政府补贴可以降低两种产品单位零售价格,增加再制造商和零售商的利润,提高消费者的剩余;当再制造产品的需求受到废旧产品回收量限制时,政府补贴可以增加两种产品的单位批发价格和两种产品制造商的利润,但是会降低零售商的销售利润.

Competition mechanism of manufacture/remanufacture considering government subsidies

The game model between an original equipment manufacturer (OEM) and a remanufacturer is established considering government subsidies for "exchanging the old with a remanufactured one".The effects of three different policies-no government subsidy at all,government subsidizing the remanufacturer,government subsidizing the consumers of remanufactured products-on the wholesale prices,retail prices,sales volume,profit,consumer surplus,and environments are compared and analyzed.The results are:when the demand for remanufactured products is not limited to recycled used products,government subsidies could reduce the unit retail price for the two products,increase the profits of remanufacturers and retailers,and raise consumer surplus;when the demand of remanufactured products is limited to recycled used products,government subsidy could increase the wholesale price of the two products and the profit of OEM and remanufacturer,and reduce the retailer's sales profit.
