经济学理论是时代的产物,必将随着社会的发展而不断被补充、修正和完善。新一轮经济危机的爆发对新古典经济学理论提出了挑战,自由放任、少政府干预、有效需求理论、"理性人"假设、一般均衡理论等遭到了质疑。本文从跨期消费和投资理论两个视角出发,分析其对新古典经济学理论的超越,揭露集聚性跨期消费和投资行为的时代缺陷,为改进和完善经济理论服务,从而合理引导跨期消费和投资理论的走向,为今后经济发展提供参考。

Economic theory is the product of the era, will be continuously supplemented, amended and improved with the development of the society. The outbreak of a new- generation economic crisis challenged the neo - classical economic theory. The laissez - faire, less govern- ment intervention, effective- demand theory, ＂ rational man＂ assumption, and general equilibrium theory has been questioned. From the perspective of intertemporal consumption and investment theory, we analyze the transcendence of the neo- classical economics theory, and reveal the epoch - limitation of concentrated intertemporal consumption and investment theory, so that to improve and perfect the economic theory. Then we propose a reasonable guide for the intertenporal consumption and investment theory, and give a reference for the economic development in the future.
