Research on Multi-Channel Supply Chain Decisions Considering Carbon Emission Cost and Consumer Loyalty

Considering carbon emission cost and consumer loyalty, this paper establishes a three-level multi-channel supply chain composed of the leading manufacturer, retailer, builds with centralized decision-making decentralized modes, optimal under both modes is solved. The study found that reduction level better than same cost, can improve level. Manufacturers open direct channel to help reduce emissions need consider in their decisions. Consumer loyalty also directly impacts Only when costs are within reasonable range new sales channels be opened bring profits. Simultaneously, total profit greater decision-making, but double marginal utility parties decreases increase costs.
