Research On The Impact Of Population Aging On China's Economic Growth

China's economy has developed rapidly depended on the huge demographic dividend since the reform and opening.With the full implementation of the family planning policy in China,the fertility rate of our country has been effectively controlled.At the same time,the mortality rate has dropped significantly and the average life expectancy is also prolonged because of the gradual improvement of basic medical facilities.Under the influence of these two effects,the population age structure of China has undergone tremendous changes,and China has been fully entered an aging society in 2000.Population aging is no longer a simple demographic problem,its structure can influence one country's economy through saving rate,human capital and other aspects.It has a more far-reaching impact on economy growth compared with population size.Moreover,since the twenty-first century,the aging of the world's population has become an irreversible fact.Therefore,the study of the impact of population aging on economic growth is important.This paper aims to study the impact of population aging to economic growth in China.It mainly focuses on the following five parts.First,it introduces the background,significance and research methods of the topic,then find out the breakthrough point by combing the researches of other scholars.The second part explains the concept and theoretical basis of population aging,and analyzes the theory from demographic perspective,economics perspective and the relationship between demography and economic growth perspective.It also discusses the transmission mechanism of population aging on savings rate,human capital formation and labor force.The third part discusses the process,status and the causes of population aging in China.This paper argues that the aging problem is the combination of the decline of the birth rate,the decline of the mortality rate and the extension of life expectancy.The fourth part builds an economic growth model containing aging,and establishes a vector autoregressive model to analyze the impact and its intensity of population aging on economic growth quantitatively.The empirical result shows that population aging will have a certain impact on economic growth and human capital,but the direction of the impact varied from different period of time.Finally,according to the mathematical analysis and empirical test results of this paper,feasible and effective policy suggestions are put forward.
