碳交易环境下再制造企业生产及减排投资决策

基于碳限额交易政策,对再制造企业生产和减排投资决策进行研究.在碳交易环境背景下,利用非线性凸优化理论,首先分析不减排投资时再制造企业的最优生产决策,然后研究再制造企业对生产新产品或再制造品减排投资时的情形.通过比较,探讨再制造企业进行减排投资时制造/再制造策略的调整,并分析减排投资对社会福利各因素(包括再制造企业利润、消费者剩余和环境影响)的影响.研究表明:对新产品(再制造品)减排将导致新产品(再制造品)产量的增加和再制造品(新产品)产量的降低;减排投资使再制造企业利润和消费者剩余均增加,但是环境影响(碳排放总量)则取决于单位再制造的碳排放量.最后,通过算例分析验证了以上结论.

Research on production and emission reduction investment decisions of the remanufacturing enterprise under carbon trading environment

Based on the carbon cap-and-trade regulation, the paper studies the production and emission reduction investment decisions of the remanufacturing enterprise. In the context of the carbon trading environment, the paper firstly analyzes the production decision of the remanufacturing company not considering emission reduction investment, and then studies the cases considering emission reduction investment in new or remanufacturing products. Through comparative analysis, we explore the adjustment of production strategies when the remanufacturing company considering emission reduction investment, and analyze the impact of emission reduction investment on social welfare(including the profit of remanufacturing enterprise, consumer surplus and environment impact). Studies show that carbon reduction investments in new products(remanufactured products) will result in the remanufacturing company expanding the production scale of new products(remanufactured products) and reducing the production of remanufactured products(new products). The emission reduction investment increases the profit of the remanufacturing enterprise and the consumer surplus, however, the environmental impact depends on the amount of carbon emissions in the remanufacturing process. Finally, the conclusions are verified by a case study.
