Abstract
Considering the e-commerce platform with a self-built logistics system as the decision-making member of E-supply chain system, the research considers the influence on the decision-making of supply chain members under the participation of e-commerce debit rate, and finally realizes the coordination of supply chain through the design of commission coordination mechanism. The article firstly constructs a decentralized decision model and a centralized decision model of the E-supply chain, determines the optimal decision of each member of the supply chain for each model, and compares and analyzes the different decision results; secondly, based on the above, the commission coordination mechanism is designed. The results of the study show that: with the increase of e-commerce deduction rate, the price of logistics service will gradually decrease, the comprehensive service level will gradually increase, and the sales price of goods will gradually decrease; under different decision-making models, there are optimal decisions to make the profit of each member in the E-supply chain system reach the optimum; the commission coordination mechanism can realize the overall coordination of E-supply chain. Finally, numerical analysis is used to verify the conclusions.
