Modeling Dynamics Of Population Migration Driven By Interest

Migration is one of the most common phenomena that the social system superimposed among th e natural and city system.Natural factors, social-economic factors, political factors, cultural factors play a main regulative role on inter-urban migration. According to the results of quantitative analysis on the behaviors of human migration among amounts of people, the researchers find that urban population appears to be the power-law distribution over time.This dissertation attempts to study the dynamic mechanics of Chinese inter-urban migration. The relevant data that are selected among31provinces and cities from China Statistical Yearbook will be used as the original data. And we will make an empirical analysis on these data to find out the relations on urban population evolution over time.In order to make a further study the dynamic mechanics of Chinese inter-urban migration, a model of urban population migration and evolution have been built. This paper makes a lattice point on selected cities and analyzes the evolution result of every lattice point. According to the result, it can be found the same power-law distribution. Moreover, we make a comparison on accumulative probability distribution of urban population. The analysis result is that the accumulative probability distribution of inter-urban migration appears to be the power-law distribution and practical survey data inosculates with model evolution result. Lastly, this paper uses the network structure diagram and the structure entropy to suggest the process population migration evolution. It provides the theoretical basis for the implementation of relevant policies and reasonable distribution of population-economic structure.
