由单位商品价值量和单位商品劳动量共同决定的单位劳动价值量是衡量资源配量效率高低的价值指标,它是由均衡价格决定的一般利润率的价值基础;同时,利润率又是单位劳动价值量的价值表现形式,两者统一于马克思的劳动价值论。在资本有机构成提高的条件下,决定单位劳动价值量的动态变化因素的是商品的价值技术弹性。 Unit labor value, which is determined jointly by unit commodity value and unit commodity labor, is a measure of the efficiency of resource allocation. It is the value basis of the general rate of profit determined by the equilibrium price. At the same time, the profit rate is the unit labor value The form of value, the two are united in Marx’s labor theory of value. Under the condition that the organic composition of capital increases, the factor that determines the dynamic change of the unit labor value is the value elasticity of the commodity.
