大多数增长模型或者基于劳动力和资本固定生产系数的假设，或者基于要素之间可替代性的假设。本文提出了一个假设，这是一个妥协之间的这些极端，即，生产的任何增加都可以通过劳动和资本投入的不同组合来获得，而任何已经安装的资本在其整个寿命期间将继续由恒定数量的劳动来操作。首先，提出了一个“一般模型”。接下来，在不同的特殊情况下求解该模型。最后，建议提出的假设将特别适合于研究新技术的引进和人口增长，储蓄率和“结构性”失业之间的关系。
Mosti growth models are based either on the assumption of fixed production coefficients for labour and capital or on the assumption of substitutability between factors. The present paper proposes a hypothesis which is a compromise between these extremes, viz., that any increment in production can be obtained by different combinations of increments in labour and capital inputs, whereas any piece of capital which is already installed will continue to be operated by a constant amount of labour throughout its life span. First, a "general model" is presented. Next, the model is solved in different special cases. In conclusion it is suggested that the proposed hypothesis would be particularly appropriate in studying the introduction of new techniques and therelationship between population growth, the rate of saving and "structural" unemployment.
