供应链企业间碳排放权共享协调策略研究

Research on Sharing and Coordination Strategy of Carbon Emissions in Supply Chain Enterprises

碳排放限制给企业运营带来了新的挑战,为实现供应链企业间碳排放权的共享协调使用,考虑由一个供应商和一个制造商组成的二级供应链,研究政府碳排放限额下的供应链企业碳排放权共享协调问题,并与无协调的情况进行比较。研究结果表明:当制造商共享碳配额后,若供应商不再被政府惩罚,碳排放权共享能提高供应链的绩效。此时,与无协调的情况相比,需求量增加,供给价格降低,且供应商和制造商的收益都增加。

Carbon emissions limits bring new challenge to enterprises, in order to achieve the sharing of carbon emission rights between enterprises of supply chain, the sharing and coordination of carbon emission permits under the carbon emissions targets of government was discussed with considering the two stage supply chain, which is consisted of a single supplier and a single manufacturer, and we fur- ther compared the result with the condition of no coordination. The research results show that when manufacturer shared carbon quotas, if the supplier is no longer punished by government, the sharing of carbon emissions rights can improve the performance of supply chain. At this point, compared with no coordination, the demand increased, the supply price reduces and the profits of supplier and man- ufacturer both increase.
