例如，资本形成发生在生产周期延长时这一说法并不重要。

The difficulty', he writes, 'of passing from gross to net capital formation, that is, the difficulty of correcting for the consumption of existing durable commodities, is not only in the lack of data.

It seems probable that capital formation and capital consumption, as used by the Austrian school of economists, are not identical either with investment and disinvestment as defined above or with net investment and disinvestment.

奥地利经济学家学派所使用的资本形成和资本消耗似乎很可能既不等同于上述定义的投资和撤资，也不等同于净投资和撤资。
