    Snippet: This study has several strengths. First, based on the theory of infectious diseases, the theory of complex network system and the characteristics of COVID-19, considering that the incubation period was still infectious, we propose an epidemic model which describes how people move between cities and spread disease; Second, the concept of "effective distance", which is not related to geographical distance, but related to transportation and populati.....
    Document: This study has several strengths. First, based on the theory of infectious diseases, the theory of complex network system and the characteristics of COVID-19, considering that the incubation period was still infectious, we propose an epidemic model which describes how people move between cities and spread disease; Second, the concept of "effective distance", which is not related to geographical distance, but related to transportation and population size, is introduced to analyze the effect of effective distance on epidemics and the transmission mechanism of the COVID-19; Third, big data and data mining technologies are used to retrieve the database of population migration data, Baidu Index and so on. Fourth, by applying the methods of descriptive statistics, multivariate analysis, econometrics, and the mathematical modeling methodology, we verified the effect of prevention and control efforts on reducing the transmission of COVID-19 among cities.
