Abstract:Due to the fact that fresh agricultural product suppliers have multiple promotion sales channels, there are differences in carbon emissions among different sales channels, with the selection of sales channels for fresh agricultural product suppliers still a problem that enterprises need to face in response to the low-carbon requirement. Therefore, profit function models have thus been constructed for four strategies: single entity channel and dual channel sales of ordinary fresh agricultural products, single channel and dual channel sales of carbon labeled fresh agricultural products, followed by an analysis of the optimal decisions of each strategy under profit maximization. Based on a comparative analysis and case study, it can be concluded that the opening of dual channels always brings higher profits to fresh agricultural product suppliers, with the sale decision of carbon labeled fresh agricultural products depending on the cost difference between the carbon labeled fresh agricultural products sold by the unit and the ordinary fresh agricultural products sold by the unit.
