This study considers a manufacturer with ambidextrous sustainable innovation capability selling products in environmentally conscious market through an independent retailer in a two-period game setting. We design a two-period game theoretic and dyadic supply chain (SC) model considering exploitative and exploratory nature of environmental innovations. We study five different contract types, namely, wholesale price contract, vertical Nash game structure, cost sharing contract, revenue sharing contract and two-part tariff contract. We demonstrate the impact of market sensitivity towards sustainable innovation and cost parameters on optimal level of decision parameters. The equilibrium results reveal that a suitably designed two-part tariff contract can be used to achieve coordination in a fragmented SC. The equilibrium results assist managers to optimise the SC based on the two-period contract model. The results obtained in this study can help the decision-makers to take decisions on investment in the ambidextrous sustainable innovation under different types of contract structures.

具有双元可持续创新的两期供应链协调策略

本研究考虑了在两阶段博弈环境中通过独立零售商在具有环保意识的市场中销售产品的双元可持续创新能力的制造商。考虑到环境创新的开发性和探索性，我们设计了一个两期博弈论和二元供应链 (SC) 模型。我们研究了五种不同的合同类型，即批发价格合同、垂直纳什博弈结构、成本分摊合同、收益分享合同和两部分关税合同。我们展示了市场敏感性对可持续创新和成本参数对决策参数最佳水平的影响。均衡结果表明，适当设计的两部分关税合同可用于在分散的 SC 中实现协调。均衡结果有助于管理者基于两期合同模型优化供应链。本研究获得的结果可以帮助决策者在不同类型的合同结构下进行双元可持续创新的投资决策。
