ABSTRACT
An aging society refers the process by which the proportion of the aged population to the total population has constantly increased. When the proportion of people aged 60 and older reaches over 10 percent of the total population or when the proportion of people aged 65 and older reaches 7 percent of the total population, the country or the region is considered an aging society. Globally, population aging reflects changes in the age structure. It is an inevitable result of the transition from a high birth rate and high death rate to a low birthrate and low death rate. But countries vary in the speed and scale of population aging and the concomitant economic conditions. Aging in developed countries is a concomitant of urbanization and industrialization and it therefore assumes an incremental process. When the population aged 65 and above reaches 7 percent, per capita GDP usually reaches 10,000 US dollars and the pressure on the economy is not big. However, in China, the demographic transition was late and fast and the scale of the population is large and the corresponding industrialization and urbanization are still in the process of development with low per capita income.2 The impact of population aging is, therefore, a problem that cannot be ignored.
