碳交易及消费补贴下的服装行业碳减排决策问题

在“双碳”目标下,全国碳交易市场悄然上线,为使服装企业更好地应对碳交易,建立由原料供应商、制造商、零售商和回收商组成的服装闭环供应链模型,着重探讨了政府对再制造服装消费者补贴及制造商碳减排投资对服装行业发展、供应链成员利润及供应链碳排放总量的影响等。研究发现:随着碳交易价格的上涨,若无减排及无补贴,服装企业难以长久维系;仅制造商投资减排的情形有利于增加传统服装、再制造服装的需求及供应链成员的利润,但同时也会刺激碳排放;既减排又补贴时,再制造消费补贴可提升制造商的最优减排率,增强再制造服装的竞争优势,降低供应链的碳排放总量;本文研究可为碳交易下服装生产企业碳减排投资决策及政府的政策制定提供指导和参考。

Decision of carbon emission-reduction in garment industry under carbon trading and consumption subsidy

With the promotion of the"dual carbon"target,the national carbon trade market has been launched without causing much attention.In order to make clothing enterprises better respond to carbon trading policy,the clothing closed-loop supply chain model was established,which was composed of raw material suppliers,manufacturers,retailers and recyclers.The impacts of government subsidies to consumers of remanufactured garment and manufacturers′investment in carbon emission reduction on the development of clothing industry,profits of supply chain members and the total supply chain carbon emission were analyzed and discussed.The study shows that the clothing enterprises could not sustain for a long time with the rise of carbon trading price without committing to emission reduction and without subsidies.The situation that only manufacturers invest in emission reduction is conducive to increasing the demand for traditional clothing and remanufactured clothing and the profits of supply chain members,but it also stimulates carbon emission.When emission reduction is combined with subsidy,the consumption subsidy of remanufactured clothing can improve the optimal emission reduction rate of manufacturers,enhance the competitive advantage of remanufactured garment,and can also reduce the total supply chain carbon emission.The research can provide reference for garment manufacturers′carbon emission reduction investment decision and government policy making under carbon trading.
