Impact Of Population Age Structure Change On Economic Growth

To study the influence of population age structure change on economic growth is conducive to the scientific formulation of economic development policy and population policy.As one of the seven major administrative regions in China,the change of population age structure brought by population change is also quietly occurring in recent years,in addition to the increasing population.At present,the economy of northwest is entering the "new normal",and the phenomenon of social aging is more and more remarkable.Obviously,under the background of rapid change of population age structure,it is of great theoretical and practical significance to explore the influence of age structure change of population in northwest China on economic growth.Based on this background,this article comprehensively uses the literature analysis method,the comparative analysis method,the demonstration research method and so on various methods to explore the Northwest region population age structure change to the economic growth influence.First of all,this paper has formed the research frame of this paper on the basis of combing and summarizing relevant domestic and foreign literatures.Secondly,this paper uses descriptive statistic method to focus on the population scale and population transition since the foundation of the Northwest China.The population dividend and age structure type of population in northwest China were judged according to the data of previous census.Thirdly,this paper mainly uses the method of empirical study to analyze the influence of population age structure change on GDP,social saving rate and residents' per capita consumption in northwest China.The results showed that the increase of fixed capital investment and employment number had a positive effect on GDP in northwest China,and the increase of total dependency coefficient had negative effect on GDP.The growth of children's dependency coefficient has a certain negative effect on the savings rate of residents in northwest China,but it has a certain positive effect on consumption.The increase of the old-age dependency coefficient has a certain positive influence on the residents ' saving rate in the northwest,which will have negative effect on the consumption,but the results are not significant.In this paper,we use the principle of statistics to forecast the change of population age structure in the future northwest.Finally,based on the results of theoretical analysis and empirical analysis,the paper puts forward some countermeasures and suggestions on how to achieve economic growth in the background of changing population age structure.
