日本人口年齡結(jié)構(gòu)對(duì)消費(fèi)影響的實(shí)證研究
[Abstract]:Consumption has always been the focus of economic research. With the emergence of Modigliani's life-cycle consumption theory, the age structure of population has become one of the factors that affect consumption. Especially now, with the increasing proportion of the world's elderly population in the total population, countries have entered the aging society, the impact of population age structure on consumption is becoming more and more prominent. Taking Japan, the world's most aging country, as the research object, this paper explores the changes in the age structure of Japan's population and its impact on the level of consumption and marginal propensity to consume. This is of great significance to China, which has just stepped into an aging society in 2002. This article systematically combs all kinds of consumption theories, and combines the existing literature to study the influencing factors of consumption. The factors that affect consumption are summarized as economic factors, institutional factors, population factors and environmental psychological factors. On the basis of combing the consumption theory, this article has carried on the qualitative analysis to the Japanese population age structure and the consumption change separately, elaborated the Japanese population quantity and the population structure two aspects between 1944 and 2015 the change characteristic. The changes of total consumption expenditure per capita actual consumption expenditure and consumption rate in Japan are described and the relationship between each index of population age structure and consumption level and consumption rate is preliminarily forecasted. This paper uses the age structure index and consumption index of Japanese population from 1980 to 2015 to construct a vector autoregressive model (VAR), using impulse response function analysis method and variance decomposition analysis method to explore the change of population proportion in three stages. Real consumption expenditure and consumption rate of the impact of the direction and size of the impact. The study shows that the change of the age structure of the population does have an impact on the consumption, the increase of the children's dependency ratio will restrain the increase of the per capita actual consumption expenditure, while the increase of the old-age dependency ratio and the proportion of workers will promote the increase of the per capita consumption expenditure. The influence of child dependency ratio on consumption rate is uncertain, and the dependency ratio of old age and the proportion of workers have positive and negative effects on consumption rate, respectively. In addition to the impact of consumption itself, the most important factor that affects the actual consumption expenditure in the short term is that the actual GDP, per capita in the long run is the child dependency ratio. The most important factor affecting consumption rate has been real GDP. per capita from beginning to end. In the long term, compared with the proportion of the elderly, the proportion of children has a greater impact on consumption. Based on the above research results, this paper puts forward some suggestions on how to make good use of the aging society in China from the angles of economic policy formulation, pension policy formulation and industrial structure adjustment.
