Research on Supply Chain Decision Making and Coordination of Community Fresh Food Platforms in the Context of Carbon Trading

Community group purchasing, as a core form of new retail, has been favored by the public for meeting consumer demand for fresh food quality and convenience, but the high-frequency transportation brought about by the increase in online purchasing has also significantly increased the carbon emissions of the supply chain.In order to maintain the low-carbon and stable development of the supply chain of the community fresh food platform, based on the three-level supply chain composed of a community e-commerce platform, a fresh food supplier and a community head, the interests of the decision-making bodies in the supply chain of the community fresh food platform under the self-managed logistics model is studied.The optimal preservation, ordering, and pricing strategies of each supply chain entity under this model is analyzed, as well as the impact of cooperation contracts on supply chain coordination, and its endogenous decision-making mechanism is explored.It is found that as the carbon trading price rises, the community e-commerce platform needs to assume greater responsibility for carbon emission reduction, and the system profit will first decrease and then increase.When adopting the combination contract, as long as the fixed costs of the two fee contracts are controlled within a reasonable interval, the supply chain system of the community fresh food platform under the self-managed logistics mode can achieve a perfect coordination.
