Broadly speaking, we shall find that they make the rate of interest to depend on the interaction of the schedule of the marginal efficiency of capital with the psychological propensity to save.

从广义上讲，我们会发现他们使利率取决于资本边际效率表与心理储蓄倾向的相互作用。

But it is the first explicit statement of the fact that capital is brought into existence not by the propensity to save but in response to the demand resulting from actual and prospective consumption.

但这是第一个明确的事实， 即资本的产生不是由于储蓄倾向， 而是对实际和预期消费产生的需求的反应。

It would, however, be an unlikely coincidence that the propensity to save in conditions of full employment should become satisfied just at the point where the stock of capital reaches the level where its marginal efficiency is zero.

然而，恰好在资本存量达到其边际效率为零的水平时，充分就业条件下的储蓄倾向应该得到满足，这不太可能是巧合。
