中文摘要：

针对同时从事制造和再制造的寡头垄断生产商,假定其第1期仅生产新品,第2期同时进行新品制造和旧件再制造生产,新品和再制造品异质且竞争替代。在整个制造/再制造生产过程中,受到外部碳排放政策（碳限额与交易政策）的约束,企业需要基于利润和碳排放约束,决策新品和再制造品的数量组合。基于构建的集成碳限额与交易约束的企业制造/再制造二阶段生产决策模型,通过模型求解、性质分析以及数值仿真,剖析碳限额与交易政策（碳限额和碳交易价格）对企业制造/再制造生产、定价、碳排放量和总利润的影响趋势和程度,探讨碳限额与交易政策约束下企业最优的制造/再制造生产策略。

英文摘要：

We study a monopoly firm that makes a new product in the first period and make new and remanufactured products in the second period. The remanufactured product is different from the new product and they are competing products in the same market, incur different carbon emissions. The firm must decide the product portfolio based on profits with carbon cap and trade mechanism. We develop a two-period profitmaximization model considering of carbon cap and trade mechanism to characterize the optimization production problem. Through the optimal solution of model and analysis of strategy and numerical experiment, we study the impact of carbon cap and trade mechanism on the enterprises manufaeturing/remanufacturing decision and pricing decision, as well as on the carbon emissions and gross profits.
