An information propagation path analysis method, comprising: acquiring propagation record information of a network (201); dividing the network into at least one community network according to the propagation record information, and determining candidate sampling nodes and an initial propagation node in each community network (202); calculating the node composition ratio of connection nodes, key nodes and ordinary nodes in the candidate sampling nodes by means of node type identifiers of the candidate sampling nodes (203); determining a sampling policy on the basis of the calculated node composition ratio and a preset node association relationship, wherein the node association relationship comprises the connection nodes being associated with the key nodes and the key nodes being associated with the ordinary nodes (204); sampling the initial propagation nodes and the candidate sampling nodes according to the sampling policy (205); and performing visual presentation on collected initial propagation nodes and candidate sampling nodes to generate an information propagation path map (206). In addition, the propagation record information can be stored in a blockchain. By means of the method, the accuracy of information propagation path analysis is improved.
