西方经济学的分析工具是经济总量的供需均衡模型,而没有分析其内部结构与非均衡过程。马克思用“两个部类”价值流通过程来分析社会再生产条件,由本质生成现象。在此基础上建立的再生产理论的主要贡献是：第一,指出简单再生产是扩大再生产的前提条件,扩大再生产要求简单再生产的两部类流通过程发生变化以趋向于新的均衡;第二,指出资本增值动力驱动下的货币贮藏（储蓄）与投放（投资）,形成货币资本系统与生产资本系统之间的流通与转换,从而对这种均衡趋势的冲击,产生下述两种非均衡趋势：一是通过货币贮藏而导致社会生产普遍过剩;二是通过投资乘数机制而导致经济增长,由此形成社会经济的起伏震荡。

The analytical tool of western economics is supply-demand equilibrium model of economic aggregate, but it does not analyze its internal structure and non-equilibrium process. Marx uses value circulation process of ＂two categories＂ to analyze social re-production conditions from the nature to phenomenon. The contribution of re-production theory on that base in- cludes： first, simple re-production is the prerequisite of expanded re-production which needs the changes in the circulation pro- cess of two categories of simple re-production to converge to new equilibrium. Second, hoard of money （savings） and input （in- vestment） driven by capital appreciation form the circulation and conversion between the system of money capital system and pro- duction capital system, which gives shocks to the equilibrium trends and leads to two types of non-equilibrium trends： one is the general surplus of social production through the hoard of money, the other is economic growth by investment multiplier mecha- nism. As a result, the fluctuation and shocks of social economy come into being.
