But, as fertility declines and populations age, the labor engine’s contribution to growth will fall sharply, to little more than 0.3 percentage points of annual growth. Even if productivity continues to rise at the same rate, global GDP growth could slow to just over 2% annually, on average – a 40% drop from the last 50 years.
但由于生育率下降及人口老龄化，经济增长劳动力引擎的贡献率将大幅下降，对年增长的贡献率仅略高于0.3%。即便生产率能保持同样的增长速度，全球GDP增长可能放缓至年均略超2个百分点——与过去50年相比下降40%。
