然而，尽管经过改进后的SEIR模型能从宏观层面刻画新产品扩散的动力学特

However, despite the improved model SEIR from macro-level new product features characterize the kinetics of diffusion, but the lack of explanatory power of the microscopic mechanism, there is still controversy over whether a true reflection of the heterogeneity of the micro level of individual behavior [ after 1, 3], and the addition of heterogeneous consumers, mathematical model validation is very challenging.

However, although the improved SEIR model can characterize the dynamics of new product diffusion from the macro level, the lack of interpretation of micro-mechanisms is still controversial in the ability to truly reflect the behavior of micro-level heterogeneous individuals, and the mathematical validation of the model is very challenging after adding the heterogeneity of consumers.
