In accordance with the regulation by “State Council’s Guiding Opinions on Carrying out New Rural Social endowment Insurance”,the individual account pension divisor coefficient of new rural social endowment insurance in China now is 139.Calculation from deducing the formula of individual account pension divisor coefficient of new rural social endowment insurance shows that the individual account pension divisor coefficient of new rural social endowment insurance is quite low,and individual accounts will face the risk of deficit in the future.The individual account of new rural social endowment insurance is full funding system and is the full account from the beginning.When deficit occurs,it is necessary to find out reasons from system design and operation instead of putting state finance to bear the responsibility.Therefore,this paper suggests that individual account pension divisor coefficient should be adjusted in proper time.Meanwhile, individual account pension should implement market-oriented investment and operation in order to increase rate of return of individual account.
