This paper first establishes a literary communication SICR model on the basis of the communication SICR model. It adopts cultural communication state transfer to construct a social network composed of N-closed individuals. Secondly, the dissemination threshold when the model reaches a stable state is discussed from the beginning and end of the literary work dissemination process. Finally, numerical simulation research using MATLAB software is used to analyze the propagation process of modern Chinese literary works, with examples provided. The results show that the number of literary ignoramuses (I) transformed into literary propagators (S) gradually rises when the initial values are
