Abstract: Firstly, the hypothesis of logistics supply chain coordination model was put forward, the profit function of manufacturers and retailers was constructed based on Stackelberg game and single cycle newsboy model, and the logistics supply chain was analyzed; in order to realize the coordination of logistics supply chain, the specific form of repurchase contract was studied; finally, an example was analyzed by MATLAB software. The results showed that under the wholesale price contract, even if the information asymmetry of agricultural products existed, it would not necessarily damage the total income of the supply chain; the repurchase contract could ensure the sharing of agricultural product information and effectively coordinate the supply chain.

Key words: information asymmetry, logistics, supply chain, agriculture products, coordination
