有些概念有广义（extensive）和狭义（intensive）之分，或者说是外延和内涵。
　　你直接翻译为 “广义和狭义的范畴” 即可。
　　具体理解如下：
　　--------------------------------------------------------------------------------------------
　　margin就是对范围的一个限定。这里是对概念范围的圈定。
　　In economics, a margin is a set of constraints conceptualised as a border.
　　Margins are sometimes conceptualized as extensive or intensive.
　　
　　extensive margin 是包含所有可用的：
　　An extensive margin corresponds to the number of usable inputs that are in some sense employed. For example, hiring an additional worker would increase an extensive margin.
　　
　　intensive margin 只包含实际在用的：
　　An intensive margin corresponds to the amount of use extracted within a given extensive margin. For example, reducing required production from a given set of workers would decrease the intensive margin.
　　
　　下面是关于“劳动力”这个概念的解释：
　　In the context of the workforce, the intensive margin can refer to people already in the workforce. The extensive margin refers to all members of the labor force, employed and unemployed.
　　intensive margin指所有在职工人的总数；而extensive margin指所有具有劳动能力的人的总数（含在职的和失业的）。
