Solow (1974) shows that, given a degree of substitutability between produced capital and natural resources, one way to design a sustainable consumption program for an economy is to accumulate produced capital sufficiently rapidly so that the pinch from the shrinking exhaustible resource stock is precisely countered by the services from the enlarged produced capital stock.
Solow （1974）指出，鉴于生产资本和自然资源之间存在一定程度的可替代性，为经济体设计可持续消费计划的一种方法是充分快速地积累生产资本，通过扩大生产资本存量提供的社会服务来精确抵消不可再生资源存量消耗的压力。
