As awareness of environmental protection increases worldwide, enterprises have been building their supply chains in ways that conserve natural resources and minimize the creation of pollutants. One of the practical ways to make supply chains more sustainable is for enterprises to utilize green innovation strategies and to increase resource reuse. In this work, we focus on a closed-loop supply chain (CLSC) consisting of a manufacturer, a retailer, and a collector. In the investigated CLSC, the manufacturer and the retailer drive the green innovation strategy either individually or simultaneously to boost market demand. In the reverse flow of the CLSC, the collector is responsible for collecting consumers' used products and transferring them to the manufacturer for remanufacturing. By combining two types of the market leadership and three types of green innovation strategies, we establish six different Stackelberg game models and solve them analytically. Through an extensive comparative analysis, we show who should have market leadership and who should drive the green innovation strategy in the CLSC. Various numerical examples are also given to support our major findings. One of our key findings suggests that the supply chain members must participate in green innovation activities at the same time to achieve a win-win scenario in the CLSC.
随着全球环保意识的提高，企业一直在以节约自然资源和减少污染物产生的方式构建其供应链。使供应链更具可持续性的一种实用方法是企业利用绿色创新战略并增加资源再利用。在这项工作中，我们专注于由制造商、零售商和回收商组成的闭环供应链 (CLSC)。在所研究的 CLSC 中，制造商和零售商分别或同时推动绿色创新战略，以促进市场需求。在 CLSC 的逆向流动中，回收商负责收集消费者使用过的产品，并将其转移给制造商进行再制造。通过结合两种类型的市场领导地位和三种类型的绿色创新战略，我们建立了六个不同的 Stackelberg 博弈模型，并进行了分析求解。通过广泛的比较分析，我们展示了在 CLSC 中谁应该拥有市场领导地位以及谁应该推动绿色创新战略。还给出了各种数值示例来支持我们的主要发现。我们的一个关键发现表明，供应链成员必须同时参与绿色创新活动，才能在 CLSC 中实现双赢局面。
