摘　　要：将Diamond的二期代际交叠模型(OLG模型)扩展为三期,并基于罗尔斯在《正义论》中对代际正义问题的探讨,对OLG模型作出了一些必要的修正;另外,通过适应预期模型对代际正义的关键问题——正义的储存进行简单的量化,在此正义的约束下通过假设消费者效用函数为常相对风险厌恶函数,求解为实现个体一生跨期消费效用的最大化而进行的储蓄;最后,进一步探讨了正义储存和传统意义上的储蓄本质上的不同,形成了一种对解决我国高储蓄问题的新探讨和新思考。In this paper, the second phase over-lapping generation model （OLG model） is extended to three periods, and based on the discussion of the issues concerning inter-generational justice in Rawls Theory of Justice, some corrections on OLG model have to be made. In addition, the storage of jus-tice, or the key problem of inter-generational justice, is simply quantified through the adaptive expec-tation model. In this case, we can calculate the savings that are intended to maximize inter-temporal consumption utility through one＇ s life by assuming that the consumer utility function proves to be aversion function of constant relative risk. At last, a kind of new exploration and thinking to solve the problem of China＇s high savings is developed through further exploring the essential difference between the justice storage and traditional savings.
