This conclusion, however, would overlook the distinction between the effects of the marginal propensity to consume and those of the average propensity to consume.

然而，这个结论会忽略边际消费倾向和平均消费倾向的影响之间的区别。

For whilst a high marginal propensity to consume involves a larger proportionate effect from a given percentage change in investment, the absolute effect will, nevertheless, be small if the average propensity to consume is also high.

因为虽然高边际消费倾向涉及给定投资百分比变化的较大比例效应， 但如果平均消费倾向也很高， 则绝对效应将很小。
