【摘要】 在环境问题日益严峻的压力下，政府和企业都在积极采取减排措施。其中，碳税政策被政府广泛采用，以旧换新（TON）和以旧换再（TOR）被制造商提供并受到政府补贴。因此，本文主要探讨存在再制造商竞争和碳税政策约束下，制造商的最优TON和TOR决策以及对应的总碳排放情况。本文构建了三个利润最大化模型，并进行了理论和数值分析，最终研究发现，当存在再制造商提供TOR竞争以及碳税政策约束时，原始制造商的最优价格和生产决策主要取决于消费者意愿和碳税率这两个方面。同时，顾客增加对制造商再制造产品的消费意愿会使得制造商的TON需求减少，TOR需求增加；顾客增加对再制造商再制造产品的消费意愿虽然不会影响制造商的TON需求，但会使得制造商的TOR需求减少。此外，本文发现，碳税率的增加总是会降低总碳排放量，但也可能使得制造商利润增加，这主要是因为制造商TOR需求的增加。更多还原

【Abstract】 Facing serious environmental problems, governments and manufacturers are taking action to reduce carbon emissions. Among these endeavors, carbon tax policy are widely adopted by governments, and trade-old-for-new(TON)and trade-old-for-remanufactured(TOR) are offered by manufacturers and subsidized by governments. To explore the effects of remanufacturer competition and carbon tax on the manufacturer’s TON and TOR decisions and the environment,we formulate three profit maximization models and present some theoretical and numerical analyses. The results show that, under the remanufacturer competition and carbon tax, the manufacturer’s optimal price and production decisions mainly depend on consumer willingness and carbon tax rate. A higher consumer willingness to manufacturer’s remanufactured products will decrease the demand for the manufacturer’s TON, but it always increases the demand for the manufacturer’s TOR. A higher consumer willingness to remanufacturer’s products will not affect the demand for the manufacturer’s TON; however, it will reduce the demand for manufacturer’s TOR. In addition, we find that a higher carbon tax rate always reduces total carbon emission reduction, and that it may increase the manufacturer’s profit due to the increase in TOR demand.更多还原
