变动的生命年金保险,是年金保险及人寿保险中有待开发的组成部分。由于该类保险能较好地适应国民经济和居民收入的变化情况,因而比固定的生命年金保险具有更强的生命力。由于每年按比例递减的生命年金保险极为罕见,故本文只打算就每年按比例递增的生命年金保险进行求算。 The variable life annuity insurance is an integral part of annuity insurance and life insurance to be developed. Because such insurance can better adapt to the changes of national economy and residents’ income, it has more vitality than fixed life annuity insurance. Since life annuity insurance, which is scaled down proportionately each year, is extremely rare, this article only intends to make a calculation on the annual annuity insurance, which increases proportionately with each year.
