Abstract: Concerning the selection of pivot points and radiant points in the spoke-and-spoke network，a model of radiation between nodes based on hyperpath was proposed. Taking Shandong area as the example，social network analysis theory，information theory，and hypergraph theory were used as the research methods. Firstly，according to the modified logistics gravity model，the relationship of logistics gravity between the nodes of the logistics network was obtained，and the relationships of logistics gravity were graded to obtain three kinds of gravitational relationships，such as strong radiation gravity，medium radiation gravity，and weak radiation gravity. Secondly，from the hypergraph theory，the quantitative relationships of different gravitational relationships were obtained，6 pivot points and 10 radiating points of the logistics network in Shandong area were determined. Finally，by using the inter-node radiation quantity model based on super-path， the radiation quantity between any two nodes was calculated，and the node with the largest radiation quantity was selected as the radiation point of the pivot point，so as to obtain the hub-and-spoke logistics network in Shandong area.
