绿色会计理论表明，在某个时间点出现负的真实储蓄意味着不可持续性。因此，最近的研究主张使用真正的储蓄措施进行实证检验：负指数意味着拒绝可持续性。然而，这一标准不能确定可持续性，因为当前的实际储蓄为正数并不排除未来的实际储蓄不足。本文在假定技术进步和资源可再生性的条件下，推导出资本-资源增长模型中长期真实储蓄的符号与持续效用的限制条件之间的一一对应关系。这一结果表明，扩展真正的储蓄方法，包括限制条件的测试：如果这个条件是经验拒绝，积极的电流真正的储蓄传递一个错误的信息。
Green accounting theories have shown that negative genuine savings at some point in time imply unsustainability. Consequently, recent studies advocate the use of the genuine savings measure for empirical testing: a negative index implies that sustainability be rejected. However, this criterion cannot ascertain sustainability, because positive current genuine savings do not rule out genuine dissaving in the future. This paper derives a one-to-one relationship between the sign of long-run genuine savings and the limiting condition for sustained utility in the capital-resource growth model, assuming technical progress and resource renewability. This result suggests to extend the genuine saving method to include a test of the limiting condition: if this condition is empirically rejected, positive current genuine savings are delivering a false message.
