碳规制下考虑碳排放转移影响的供应链企业最优运营策略研究

Research on Optimal Operation Strategy of Supply Chain Enterprises Considering Carbon Emission Transfer under Carbon Regulation

摘要:

主要研究供应商碳配额不足、制造商碳配额富余、零售商碳配额富余情景下，考虑碳排放转移影响的三级供应链企业间最优运营策略问题。运用变分不等式理论构建超网络模型，研究结果表明：(1)网络内生性的碳排放转移率能弥补供应商碳配额不足，有助于确保网络均衡状态下供应商碳排放量在政府规定的碳配额范围之内；(2)随着碳排放转移率的升高，供应链超网络的网络均衡交易数量总体呈现下降趋势，网络均衡交易价格总体呈上升趋势；(3)由于碳排放转移效应的存在，供应链整体的利润下降，供应链企业应警惕碳排放转移带来的影响。

Abstract:

This paper mainly studies the optimal operation strategy of three-tier supply chain enterprises considering the impact of carbon emission shift under the scenario of insufficient supplier carbon allowance, manufacturer carbon allowance surplus and retailer carbon allowance surplus. The super-network model is constructed by using the variational inequality theory. The results show that: (1) The endogenous carbon emission transfer rate of the network can make up for the insufficient carbon quota of the supplier, which helps to ensure the supplier's carbon emission under the network equilibrium state. (2) As the carbon emission transfer rate increases, the number of network equilibrium transactions in the supply chain super network generally shows a downward trend, and the network equilibrium transaction price generally shows an upward trend. (3) Due to carbon emission shift, the existence of the effect, the overall profit of the supply chain declines, supply chain enterprises should be alert to the impact of carbon emissions transfer.
