The invention discloses a statistical analysis method, system and equipment for key time parameters of an infectious disease transmission chain and a medium. The method comprises the following steps: acquiring statistical data of an incubation period and a sequence interval based on infectious disease contact tracking data; according to the statistical data of the incubation period and the sequence interval, constructing a statistical model for jointly estimating the incubation period and the intergenerational interval distribution parameters, wherein the statistical model for jointly estimating the incubation period and the intergenerational interval distribution parameters is used for estimating the incubation period distribution parameters and the intergenerational interval distribution parameters; calculating the asymptomatic propagation proportion according to the estimated incubation period distribution parameters and the inter-generation interval distribution parameters; and estimating the average valu
