中文摘要：

为分析专利费用对再制造产品销售市场的影响,本文以当前政府“以旧换再”补贴政策为背景,建立了新产品制造商和再制造商博弈模型.对比分析了两种情形下,专利费用对政府补贴、废旧产品边界回收率、零售价格、销售利润、消费者剩余、社会剩余及环境的影响.研究结果表明：新产品制造商对再制造产品制造商征收的专利费用与再制造产品节省成本及政府补贴额度成正比;不收取专利费用时,新产品销售利润与政府补贴成反比,收取专利费用时,其利润与政府补贴成正比;再制造产品需求不受废旧产品回收率限制及新产品制造商不收取专利费用情形下,消费者剩余和社会剩余最大;两种情形对环境的影响与两种产品的环境影响比有关.

英文摘要：

In the background of government subsidies for exchanging old with remanufactured ones, this paper establishes a game model between a manufacturer and a remanufacturer, in order to analyze the effect of patent fees on the remanufactured products＇ sales market. It comparatively analyzes the influence of patent fees on government subsidies, margin return rates of waste products, retail prices, sales profits, consumer surplus, social surplus, and environments under two conditions （one is that a manufacturer does not charge for the patent fee and the other is that a manufacturer charges for the patent fee）. The results show that： the patent fee is proportional to the remanufacturing cost savings and government subsidies; sales profits of new products are inversely proportional to government subsidies without the patent fee and proportional to government subsidies with the patent fee; consumer surplus and social surplus are the largest without the patent fee when the demand for remanufactured products is not subject to the restrictions of waste product recovery; the environmental impact under the two conditions is related to the environmental impact for the two products.
