The Impact Of Population Aging On The Savings Rate In Japan

Japan is in the leading position among country which have the highest level of population aging.Japan entered the aging society as early as 1970,and took only 24 years for old age ratio doubling(from 7% to 14%).In 2007,Japan entered the super-aging society,which is much faster than other countries.The aging of the population is developing very rapidly and the deepest degree,the serious population aging Transformation affects all aspects of Japan's economy and society.It has been30 years since the Japanese economic bubble burst,but Japan 's economic stagnation has continued.With the deepening of Japan's population aging,the impact of aging on the economy has become prominent,and more and more scholars have begun to explain the long-term stagnation of the Japanese economy from the perspective of population aging.According to the life cycle theory,the most intuitive effect of population aging on the economy is savings,so this article chooses the saving rate as the entry point to study the impact of Japan's population aging on the savings rate.China's population is aging ahead of schedule,with the phenomenon of "getting old before getting rich".When the "demographic dividend" is about to disappear,the issue of coping with population aging needs to be put on the agenda urgently.This article studies the relationship between Japan's aging population and the savings rate,and aims to provide a forward-looking theoretical basis for China's response to the problem of population aging,and provides policy recommendations from the perspective of the savings rate to mitigate the impact of the decline in the savings rate on the economy.This article conducts research from the following aspects: The first part is the first three chapters,mainly related to the research background,literature and theoretical basis,the first chapter introduces the relevant background,research methods,literature review and other contents,and the second chapter mainly introduces the Keynesian consumption-saving theory,Life cycle theory,permanent income theory,random walk hypothesis,preventive savings theory and life expectancy effect,Chapter 3 analyzes the savings rate caused by population agingfrom three paths: the household savings rate,the enterprise savings rate and the government savings rate.The second part is Chapter 4,which introduces the changing trend of Japan's aging population and saving rate,and analyzes the impact of Japan's aging population on the saving rate in combination with data.The third part is Chapter5.Through empirical research,an econometric model is used to analyze the relevant data in Japan,proving that the aging population has a significant negative impact on the Japanese savings rate.The fourth part is Chapter 6,which analyzes the current problems faced by China and the challenges that may arise in the future,draws on Japan's relevant experience,and puts forward relevant policy recommendations for China's national conditions.
