目前,日本人口在世界上的老龄化速度非常快,人口老龄化会使年轻一代的缴费负担日益加重,从而使年轻一代对日本公共养老金体制产生信任危机,而事实上日本现收现付的公共养老金体制已经难以适应人口老龄化到来时养老保险费用膨胀的需要。因此本文认为日本未来的改革趋势是对公共养老金实行基金积累制。 At present, Japan’s population is aging at a very fast rate in the world. The aging population will make the young generation pay a heavier burden so that the younger generation will have a crisis of confidence in Japan’s public pension system. In fact, Japan is paying off Public pension system has been difficult to adapt to the needs of the population when the aging of old age insurance costs. Therefore, this paper argues that Japan’s future reform trend is to implement the system of accumulation of funds for public pensions.
