The invention provides a social Internet of Things information propagation model and a caching strategy, and the method comprises the following steps: S1, abstracting communication between devices in the social Internet of Things into an information propagation process, providing a hierarchical information propagation model (L-SICR) facing the social Internet of Things, and building a propagation kinetic equation of the model based on a microscopic Markov chain method; s2, performing theoretical analysis on the information propagation threshold; and S3, comprehensively considering social attributes of the nodes and global and local information popularity, and formulating an information dynamic caching strategy (DCS). And S4, performing information propagation simulation based on an artificial network and an actual network. According to the method, the information spreading process in the social internet of things network can be well predicted according to the network structure information, the user node attri
