Averaging the numbers assumes that all components are substitutes: if you cannot improve on one, you can compensate by improving on another. But I think of them as complements: if you cannot build your plant, you do not benefit from more accommodating trade rules.
包括我在内的一批人发现基础指标比平均指标包含的信息量更大。数字平均化假设所有成分都是替代性的：如果你无法改善甲数字，你可以通过改善乙数字作为补偿。但我认为这些指标是互补性的：如果你无法建立你的工厂，就无法通过调整贸易规则获益。一个问题就可以是致命的，即使其他指标十分强大。
