A primary dilemma for multinational firms facing different emissions reduction regulations is determining what to produce in-house and what to outsource. We study a supply chain with manufacturers and overseas suppliers each facing different carbon tax rates. We present an in-house production and outsourcing equilibrium decision model as well as a modified projection algorithm for this supply chain. Numerical examples focus on examining how carbon tax rates and consumer’s carbon awareness affect in-house production and outsourcing decisions. Analysis of the numerical results provides important managerial insights and carbon policy implications which are thoroughly discussed in this paper.

对于面临不同减排法规的跨国公司来说，一个主要的困境是决定内部生产什么，外包什么。我们研究了制造商和海外供应商的供应链，每个供应商都面临不同的碳税率。我们提出了一个内部生产和外包均衡决策模型以及该供应链的改进投影算法。数值示例侧重于研究碳税率和消费者的碳意识如何影响内部生产和外包决策。对数值结果的分析提供了重要的管理见解和碳政策含义，本文对此进行了深入讨论。
