摘要
随着生育水平的下降与预期寿命的延长,我国人口年龄结构已发生了极大转变。人口年龄结构的变动势必对经济增长及结构产生重大影响。为此,本文模拟一种理想状态,采用CGE模型定量分析仅人口年龄结构变动(假定城乡人口总数保持基年水平不变)对我国经济发展的影响。模拟结果表明,仅人口年龄结构变动将使我国经济总量呈现出缩减的趋势,对消费结构与产业结构产生一定影响,同时使养老金与医疗保险支出迅速增加,进而增大累计债务,加重财政负担。这对我国制定适宜人口政策,把握产业结构发展方向,维持社会经济稳定、健康、持续发展具有一定启示意义。
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. 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 financial burden. It is important significance for making population policy, grasping the development trend of industrial structure,maintaining economy stable and healthy sustainable development.
