Analysis on System dynamics of Population Migration and Population Urbanization in Shaanxi Province

By using the method of system dynamics,an analysis on the population migration and population urbanization in Shaanxi Province is made and a prediction model of the population urbanization level is constructed.From systematic simulation analysis,it has been revealed that the growth of the difference of income between urban and rural areas will give rise to the massive migration of the rural population to cities,thus speeding up the process of urbanization;the scientific and technological level imposes expressed impact on the migration between rural and urban areas;when the labor productivity is raised,this will result in the reduction of the scale of the rural and urban population migration,thus posing a given influence on the population urbanization level.However,the lowering of labor production is only able to boost the rural population migration to cities,and this cannot raise the urbanization level in the long run.When the land in rural areas is subject to strict control,there will be a definite inhibition effect on the population migration.When the natural growth rate of the rural population increases,the migrating population between rural and urban areas will be augmented to some degree and the population urbanization level will be reduced somewhat.
