邊際效用遞減（diminishing marginal utility）是經濟學中的基礎概念，指消費者連續消費某一商品時，每增加一單位消費所獲得的額外效用（滿足感）逐漸減少的現象。這一規律由19世紀經濟學家赫爾曼·海因裡希·戈森（Hermann Heinrich Gossen）首次系統闡述，後經威廉·斯坦利·傑文斯（William Stanley Jevons）等學者完善。
核心解釋
以飲水為例：當一個人極度口渴時，第一杯水帶來的滿足感最高；第二杯水的效用次之；當飲用量達到飽和後，額外一杯水可能産生零效用甚至負效用（如腹脹不適）。這種邊際效用隨消費量增加而遞減的趨勢，反映了人類需求滿足的非線性特征。
數學表達
邊際效用公式可表示為：
$$
MU = frac{Delta TU}{Delta Q}
$$
其中，MU為邊際效用，ΔTU為總效用變化量，ΔQ為消費量變化量。隨着Q增加，MU呈現遞減趨勢。
現實應用
該原理被廣泛應用于定價策略與政策制定。例如：電力公司對超額用電實施階梯電價，即基于用電量越高、單位電價越高的原則，符合邊際效用遞減規律。在公共政策中，累進所得稅制也體現了高收入者貨币邊際效用較低的理論基礎。
"Diminishing marginal utility"（邊際效用遞減）是經濟學中的一個核心概念，主要用于描述消費者行為。其核心含義是：隨着某種商品或服務消費量的連續增加，每新增一單位消費所帶來的額外效用（滿足感）會逐漸減少。以下是詳細解釋：
例如：
饑餓時吃第一個包子帶來的滿足感最大，第二個次之，吃到第五個時可能已感到不適，此時邊際效用為負。
邊際效用公式為：
$$ MU = frac{Delta TU}{Delta Q} $$
其中，( MU ) 是邊際效用，( Delta TU ) 是總效用的變化量，( Delta Q ) 是消費量的變化量。
隨着消費量 ( Q ) 增加，( MU ) 逐漸減小，最終趨近于零或負數。
若需進一步了解邊際效用的曆史背景（如戈森第一定律）或與其他經濟模型的關聯（如無差異曲線），可參考經濟學教材或相關文獻。
