本文的成果主要体现在两个方面:第一,将时间维度导入效用函数,实现了对边际效用递减规律认识的一次真正的飞跃；第二,将需求在需求要素的层次上进行分解,使边际效用递减规律有了更为准确和牢靠的基础.在这两个成果的基础上,对效用的可测量性、商品的同质性假说等问题进生了前瞻性的探讨.%Two main progresses were made in the research of the law of diminishing marginal utility in this paper. One of the great strides was the integration of time dimension into the utility function with the result of bettering the understanding of the diminishing marginal utility law. The other great strides was the fundamental decomposition of the demand at die level of Demand elements so that the diminishing marginal utility law has more accurate and solid bases. Furthermore, this paper conducted the prospective study of the law of diminishing marginal utility on the measurability of the utility, and the commodity homogeneity hypothesis.
