The environmental awareness of consumers and enterprises has gradually increased, and green production and green consumption have become the main theme of social economy. On the other hand, the complementary product market has become an important source of competitive advantage for enterprises. Considering a complementary product supply chain, and taking account of the consumers' environmental awareness and the green subsidies provided by the government, this paper examines members' decisions in relation to four contract models based on game theory. By solving the model, it is shown that the government's green subsidy plan improves the green degree of subsidized products and complementary products. Furthermore, compared to wholesale price contracts, revenue-sharing and cost-sharing contracts motivate manufacturers to improve the greenness of subsidized products, and they achieve a Pareto improvement for the whole supply chain and its members, when the contract parameters are appropriate. Numerical experiments also reveal that both the greenness of the complementary products and the profit for members increase with the green innovation spillover effect as a result of the complementary products and the scale of green consumers with environmental awareness in the market. This study provides good guidance for decision-making concerning the complementary product supply chain, and further contributes to environmental protection.
消费者和企业的环保意识逐渐增强，绿色生产和绿色消费已成为社会经济的主题。另一方面，互补产品市场已成为企业竞争优势的重要来源。考虑到一个互补产品供应链，并考虑到消费者的环保意识和政府提供的绿色补贴，本文基于博弈论研究了四个合同模型下成员的决策。通过求解模型，结果表明政府的绿色补贴计划提高了补贴产品和互补产品的绿色度。此外，与批发价格合同相比，收益共享和成本共享合同激励制造商提高补贴产品的绿色度，并且在合同参数适当的情况下，为整个供应链及其成员实现了帕累托改进。数值实验还表明，随着互补产品的绿色度和具有环境意识的绿色消费者的市场规模的增加，互补产品的绿色度和成员的利润都随之增加。本研究为互补产品供应链的决策提供了良好的指导，进一步有助于环境保护。
