Investment rate

The investment rate is calculated by dividing gross fixed capital formation by gross value added at current prices. This is multiplied by 100 to express it as a percentage of value added.投资率的计算方法为：以现行价格（current prices）计算的固定资本形成总额（gross fixed capital formation）除以总增加值（gross value added）。将该结果乘以100，即可表示为增加值的百分比。
