Coordination of Cross-Border Supply Chains Based on Differential Game under Carbon Price Asymmetry
摘要
Abstract
The implementation of the Carbon Border Adjustment Mechanism(CBAM)by the European Union intensifies the uncertainty and disruption risks of cross-border supply chains under asymmetric carbon prices.This study considered a cross-border supply chain composed of a manufacturer in a developing country,a retailer within the CBAM jurisdiction,and a third-party international freight forwarder.Based on a differential game model,it compared equilibrium strategies under decentralized and centralized decisions and introduced a bilateral cost-sharing contract to achieve coordination.The study finds that the manufacturer's emission reduction effort is proportional to the degree of carbon price asymmetry.A greater degree of carbon price asymmetry narrows the feasible range of cost-sharing ratios and may result in contract failure under extreme conditions.Within a moderate cost-sharing range,the contract enables reasonable cost allocation and mutual benefits.However,when the retailer's share of the manufacturer's emission reduction cost exceeds a threshold,maintaining coordination requires the retailer to avoid short-sighted behavior.This study provides theoretical support for supply chain coordination and emission reduction decisions under carbon price asymmetry.关键词
