According to the classical Bass model,a product information diffusion model was proposed based on user experiences from the perspective of consumers.In the light of the model,the relationship between the total number of product users and the channel coefficient as well as the impact of unpleasant experiences on the purchase of products were analyzed by using mathematical methods for solving differential equations.Then,the model was validated under different parameters conditions by simulation ananlysis on the influence of two types of informations on the classic and new products information diffusion and on the diffusion status differences.Finally,the analog data and charts resulted from the model simulation were analyzed and a policy which can enable enterprises to continue to operate and win the market share was proposed.Some conclusions and constructive suggestions were provided,which help the product to expand the competitive market.Moreover,guidances and theoretical supports for the strategic formulation were also suggested.
