The Pension insurance,as an essential component of the social insurance,is also one of the core components in total social security system.The current pooling level of pension insurance is not high, so it is difficult to play a part in helping each other and spreading the risk.Gradually raise the pooling level to lower risk funds and improve the level of protection, to achieve the ultimate realization of the national level at base of the provincial level. It not only meet the essential requirement of the socialization of pension insurance, but also the developing direction of the pension insurance system in our country.In this paper, the author first hackle the related concept of unified basic pension insurance, the theoretical basis and practical basis of pension insurance. Take Guangdong province for example, analyse the current level of development of pension insurance, and analyse income redistribution and its effects in the process of provincial level. Specifically, the author study income redistribution of the unified pension treatment to the representative areas of different income groups, apply annuities, discounted present value model to make empirical analysis, it demonstrate that although the new pension payment method can establish incentive mechanism for participation in the schemes on adding the payment amount or extending payment age in a certain way, resulting in impaired intragenerational redistribution interdependent function, so put forward paying attention to the correction of Matthew effect in process of implementing the new method, to prevent the international inequality in redistribution. Besides, the author study unified payment provides, study the fund's income redistribution if representative areas gradually unify the ratio of payment in Guangdong province, apply grey system prediction model and the fund of income and expenditure model to make empirical analysis, it demonstrate that the pension burden in Zhongshan city will be less and less, and the increasingly heavy burden in Zhanjiang under the existing ratio. The sensitivity analysis on the ratio of payment shows that both intensify adjustment and delay the adjustment time will widen the gap between representative areas. Therefore, the pace of unification should be step by step and gradually accelerate. The sooner adjustment, and grasp of the pace well, the better adjustment of interests between parties.
