As the decline of fertility and the extension of life expectancy,the population age structure has had the great change.The population age structure changes must have a signifi cant impact on the economic growth and economic structure. To this end,this article assumes an ideal situation that urban and rural population remain constant in base year level, it quantitatively analyzes the impact of changes of only population age structure using the CGE model. Simulation study shows that the only population age structure changes make the economy show a reduced tendency,also have certain influence on consumption structure and industrial structure, make pension insurance and medical insurance expenditure increase rapidly at the same time, thus increase the accumulated debt and the fi nancial burden. It is important signifi cance for making population policy,grasping the development trend of industrial structure, maintaining economy stable and healthy sustainable development.
As the decline of fertility and the extension of life expectancy, the population age structure has had the great change.The population age structure changes must have a significant impact on the economic growth and economic structure.
