摘　　要：在宏观经济学中常使用两个以微观为基础的基本模型来分析消费和投资的优化问题:其一是拉姆赛提出的无限期界模型;其二是萨缪尔森和戴蒙得提出的世代交叠模型。结合这两个基本模型的假设,可以构造一个扩展的无限期界的模型。根据这一模型分析,我国需求的支撑重心要逐步从过分倚重固定资产投资,向消费需求和投资需求均衡支撑过渡;经济增长的动力机制应从目前的投资主导型向居民消费和社会投资双轮驱动型转换。There are two micro-patterns used to analyse the optimal problem in macro-economics:One is the indefinite pattern put forward by Lamsy;and second is the overlap pattern put forward by Samurson and Daimon.Combined these two basic patterns,an indefinite pattern could be built up and meanwhile a negative problem can be raised.According to this analysis,the core of our demand should transit over-dependent capital into the consumption demand and investment demand.The energetic mechanism of the economic growth should change from the investment to the residential consumption and social investment.
