In recent years, the rapid development of China's economy has driven the booming logistics industry, and then puts forward higher requirements for the ability and efficiency of the express industry. High-speed rail express, as a new mode of transportation, will play an important role in the improvement of China's logistics capacity. At present, most studies on high-speed rail express network are based on the hub-and-spoke network. This paper firstly analyzes the advantages and disadvantages of fully connected network and pure hub-and-spoke network, and then proposes the necessity of constructing hybrid hub-and-spoke network in high-speed rail express. Then, with the goal of minimizing the total cost of network transportation, an integer programming model is established to construct a hybrid hub-and-spoke network of high-speed rail express, considering the constraints of node operation ability and number of hubs, and a numerical experiment is designed to solve and verify the model. The influence of number of hubs on the optimal target value is analyzed, and the proportion of OD flow taking different transportation modes is calculated. Finally, the optimal target values of fully connected network, pure hub-and-spoke network and hybrid hub-and-spoke network are compared, and it is found that the use of hybrid hub-and-spoke network in the fast freight transportation of high-speed rail can not only exert the scale effect, but also effectively reduce the detour transportation to save the transportation cost.
