劳动生产率与商品价值量变化关系探讨

On Changing Relationships Between Labor Productivity and Goods Value Quantity

只有劳动生产率变化而劳动量不变的假定成立时,单位商品价值与劳动生产率成反比才能成立。然而,当劳动生产率提高时,生产商品的物化劳动和活劳动都会增加,从而生产商品的劳动量增加。同时,劳动生产率变化还会使商品供求关系变化,从而使价值总量发生变化。因此,单位商品价值与劳动生产率不成反比。一般来说,单位商品价值与劳动生产率成反方向变化。

When the labor productivity is variable,the labor capacity is not unvariable. The inverse ratio between the unit goods value and the labor productivity is able to be established. However,when labor productivity rises,the materialized production commodity materialized labor and living labor are to increase, so labor capacity of production commodity is able to increase. The change of labor productivity also can cause the change of the commodity supply and demand relations thus the total value quantity is changed. Therefore, unit goods value and labor productivity are not inverse ratio. Generally speaking,the unit goods value and the labor productivity become the reversed direction change.
