碳交易政策下供应链碳减排与低碳宣传的微分对策研究

为分析不同类型的碳交易政策对供应链中企业运营产生的长期影响，在考虑产品商誉能够影响消费者需求且具有动态变化过程的基础上，构建了供应链中制造商和零售商的三种微分博弈模型。研究结果表明：与没有碳交易相比，基于企业碳排放历史数据的碳交易政策的实施能够从长期角度提升制造商产品的碳减排水平和零售商的低碳宣传水平，同时产品最终的商誉和零售商的利润也有所增长；此外，基于产品碳排放数据的碳交易政策的实施能够进一步提升产品的碳减排水平、商誉和零售商利润，而零售商的低碳宣传水平保持不变；当政府的政策满足特定条件时，基于产品碳排放数据的碳交易政策对制造商更有利。

Differential Strategies of Carbon Emission Reduction and Low-carbon Promotion of the Supply Chain under Cap-and-trade Policy

With the rapid modernization and urbanization, environmental issues such as global warming caused by carbon emissions are attracted more attention by the international community. Due to its advantages on flexibility and implementation, cap-and-trade regulations are considered as an effective mechanism for supply chains to reduce carbon emissions.In order to analyze long-term impact of different cap-and-trade policies on low-carbon operations of enterprises in the supply chain, three differential game models between the manufacturer and the retailer in a supply chain are established, which are based on the consideration of influencing effects on market demands and dynamic features of the goodwill. In our model, both cap-and-trade regulations and the goodwill of the product are considered, and the goodwill of the product is affected by carbon emission reduction efforts of the manufacturer and low-carbon promotion efforts of the retailer. Compared with no cap-and-trade regulation, carbon emission reduction level of the product and low-carbon promotion level of the retailer can be improved by the implementation of the cap-and-trade policy based on enterprise’s historical carbon emission data. Furthermore, the goodwill of the product and retailer’s profits canalso be improved from the long-term perspective. Compared with cap-and-trade policy based on enterprise’s historical carbon emission data, carbon emission reduction level,the goodwill of the product and retailer’s profits can be further improved by the implementation of the cap-and-trade policy based on product’s carbon emission data, although low-carbon promotion level of the retaileris the same. Once certain conditions of government’s policies are met, the cap-and-trade policy driven by product’s carbon emission data is more beneficial for the manufacturer. Management insights for carbon emission reduction strategies of supply chain members are provided by our research.
