Abstract："Belt- plate transportation" can effectively improve the efficiency of urban distribution. The pallets of logistics company dominate the entire pallet market，so the effective circulation of pallet resources under the way of shared scheduling has become one of the research hotspots. Considering a large number of pallets in logistics companies on the background of shared scheduling and the situation of non-cooperation and cooperation of logistics companies，based on the multi-point scheduling of a single logistics company，the multi-point sharing scheduling of multiple logistics companies is studied. Besides，inventory cost， leasing cost，and scheduling cost are taken as the influencing factors，and the integer programming pallet sharing scheduling model is established according to the multi-cycle transportation thinking. The program of solving the model is compiled with the help of MATLAB software and the validity of the model is verified by an example. The results show that，under the cooperation mode of logistics companies，pallet sharing and scheduling can achieve the goal of effective resource circulation and the lowest total logistics cost. The cost of renting pallets is obviously higher in the non-cooperative mode of logistics companies. The sharing and scheduling of pallets under the cooperative mode gives priority to the idle pallets of logistics companies，which can effectively reduce the cost of renting pallets or purchasing pallets and improve the efficiency of resource recycling. The Shared pallet scheduling based on the cooperation mode of logistics companies realizes the recycling of their own resources，effectively promotes the efficiency of urban distribution services.
