老师，请问labor cost in total factor cost（%）这一项是指（1-α）吗？

问题如下：

Medeva says, "I'm glad to see the data in Exhibit 1. However, I would be more interested in measuring the growth rate in potential GDP using the labor productivity growth accounting equation. It will help me to consider increasing equity exposure to the country with the highest growth rate in potential GDP."

Using the approach suggested by Medeva and the data in Exhibit 1, which of the three countries most likely indicates the highest growth rate in potential GDP?

选项：

A.Country X B.Country Z C.Country Y

解释：

Using the labor productivity growth accounting equation, Country Z indicates the highest growth rate in potential GDP.

Growth rate in potential GDP = Long-term growth rate of labor force + Long-term growth rate in labor productivity

使用劳动生产率增长方程，Z国表示潜在GDP增长率最高。

潜在GDP增长率=长期劳动力增长率+长期劳动生产率增长率，具体计算结果参考上表。
