Second, we propose a new model based on coupled with improved HAM SEIR model binding model. Traditional SEIR epidemic model improvements, combined with heterogeneous body of empirical simulation model to overcome the macro-dynamics model depicts only superficial defects. The coupling mechanism of nonlinear dynamics model can explain new product diffusion from the micro-level, bridges the gap between macro and micro.

Secondly, a new coupling model based on the combination of improved SEIR model and HAM model is proposed. The traditional SEIR epidemiological model is improved, combined with the heterogeneous subject model, and the empirical simulation experiment sifts through the defect skew of the surface phenomenon from the macrodynamic model only. The coupling model can explain the nonlinear dynamics mechanism of new product diffusion from the microlevel level, and build a bridge between macro microscopic.

Secondly, a new coupling model based on the combination of improved SEIR model and ham model is proposed. The traditional SEIR epidemic model is improved, and the empirical simulation experiment is carried out with the heterogeneous agent model, which overcomes the defect of only describing the surface phenomenon from the macro dynamic model. The coupling model can explain the non-linear dynamic mechanism of new product diffusion from the micro level and build a bridge between macro and micro level.
