Marginal rate of transformation

中文百科

生产可能性曲线 Production–possibility frontier

(重定向自Marginal rate of transformation)

在经济学中,生产可能性曲线Production Possibility CurveProduction Possibilities Frontier,简称PPCPPF)是指用来描述在已知条件下,两种产品之间在用尽所有资源、技术的情况下所有的生产组合的可能,在平面图上所形成之轨迹。

生产可能性曲线是一个简单的经济学模型,这模型有数个假设::

生产可能性曲线便表达了在资源用尽的时候,两种产品可被生产的不同组合。换句话说,曲在线的移动均反映了机会成本,因为生产资源是有限的,经济体系的生产组合不可能在曲线右方,要想多生产甲物品,便必须放弃某数量的乙物品,省下资源作甲的生产。另一方面,曲在线的生产组合又代表最高效率的生产,没有任何资源闲置。处于曲线以内的区域,生产组合可生产,但生产效率较低,因为资源未被尽用。

(重定向自Marginal rate of transformation)
An example PPF with illustrative points marked
Increasing butter from A to B carries little opportunity cost, but for C to D the cost is great.
Marginal rate of transformation increases when the transition is made from AA to BB.
A common PPF: increasing opportunity costA straight line PPF: constant opportunity costAn inverted PPF: decreasing opportunity cost

PPF is a Graphical representation of possible combination of two goods with a constant resources and technology.

In economics, a production–possibility frontier (PPF), sometimes called a production–possibility curve, production-possibility boundary or product transformation curve, is a graph representing production tradeoffs of an economy given fixed resources. It is a graphical representation of the maximal mix of outputs that an economy can achieve using its existing resources to full extent and in the most efficient way.
