关于三种价值论的评论

传统劳动价值论存在四大问题:一是社会必要劳动量难以计量;二是复杂劳动和简单劳动的倍加比例难以准确确定;三是无法解释自然产品为何也具有价值、价格;四是存在价值归属上的理论悖论。生产要素价值论不能全盘否定,但资本、土地不能“创造”价值,只能“生成”价值。边际效用价值论所揭示的边际效用递减规律是正确的;应当正确看待用效用衡量商品价值;事实上,马克思的商品价值论与边际效用价值论具有相通之处。

A Review on Three Theories of Value

Four issues remain unresolved with the conventional theory on labor value:first,the necessary social labor is difficult to measure in quantity;second,complicated work and simple work are hard to ascertain with accuracy in terms of multiplication and addition;third,it is impossible to explain why natural products also have prices and values;there still exists a theoretical paradox with regard to the value affiliation,i.e.,the theory of production factors can not be completely overthrown while capital and land can not "create" value,but only "generate" value.The law of the diminishing marginal benefit expressed in the marginal benefit theory is correct;commodity evaluation in terms of their benefit needs to be justified;in fact,the theory of commodity value by Karl Marx and the theory of marginal benefit value are relevant to each other.
