商品价值是由生产商品的社会必要劳动时间决定,而不是由均衡价格决定,价值的本质是计量社会劳动的工具,是社会公平分配的依据。随着时代发展,创造商品价值的劳动不能单纯限定在物质生产部门,凡是有利于增加社会福利的活动都创造价值,都应依据其一般劳动耗费而取得相应的利益回报。 The value of a commodity is determined by the socially necessary working time of producing the commodity, not by the equilibrium price. The essence of the value is a measure of social labor and a basis for the fair distribution of the society. With the development of the times, the labor that creates the value of the commodity can not be confined to the material production sector. Any activity that contributes to the increase of the social welfare creates value. All these should be rewarded according to their general labor cost.
