两种含义的社会必要劳动时间与价值决定新探

A Review of the Dual Implications of Socially Necessary Labor-Time and Commodity Value Determined

从生产和供给的角度重新解释了第1种含义的社会必要劳动时间(必要劳动Ⅰ),从消费和需求的角度重新解释了第2种含义的社会必要劳动时间(必要劳动Ⅱ),在此基础上论证了两种含义的社会必要劳动时间共同决定商品价值的观点;区分了单位商品必要劳动Ⅱ的变化和必要劳动Ⅱ本身的变化,并引入时间因素进行比较静态分析,探讨了短期波动和价值决定的多种具体情况。认为马克思提出第2种含义的社会必要劳动时间,反映了马克思试图将其价值决定中外生化的需求因素内生化的一种努力。

The paper starts with a new interpretation of the dual implications of Socially Necessary LaborTime (i.e. Necessary Labor Ⅰ and Necessary Labor Ⅱ) in terms of production & supply and consumption & demand respectively, and then illustrates the point that commodity value is virtually determined by the two Socially Necessary Time. It also distinguishes between changes of Necessary Labor Ⅱ for separate commodities and of Necessary Labor Ⅱ proper, introduces the time factor into a comparative, static analysis of the Necessary Labor and discusses various possibilities concerning shortterm fluctuation and value determined. In conclusion, it points out that Carl Marx, with his proposal of the second implication of Socially Necessary Labortime, intends to switch demand factor in value determination from the exogenous facet to the endogenous one.
