问题如下：
Economic data of a country is showed below:
According to the economic data, which of the three counties most likely rely on the capital deepening?
选项：
A.Country X.
B.Country Y.
C.Country Z.
解释：
A is correct.
考点：Cobb-Douglas production function 的变形公式
解析：先写出变形公式：
Growth rate of labor productivity= Growth rate of TFP+ Growth rate of capital deepening（假设劳动力恒定不变）
capital deepening%=△y/y-△T/T
X=2.6-0.8=1.8
Y=1.8-1=0.8
Z=1-(-0.1) =1.1
这个公式怎么得出来的，课上没听到

嗨，从没放弃的小努力你好：
同学你好，本题考查的是R11-Cobb-Douglas 的变形公式
Y=T*K^(alpha）*L(1-alpha）
左右两边同时除以L
（Y/L)=T *(K/L)^(alpha）
Y/L：labor productivity
T：TFP
K/L：capital deepening
假定L不变两边取对数求出下面式子
Growth rate of labor productivity= Growth rate of TFP+ Growth rate of capital deepening（假设劳动力恒定不变）
TFP指的是total factor productivity,reflects the general level of productivity or technology in the economy.描述的是技术进步对经济的影响。
-------------------------------加油吧，让我们一起遇见更好的自己！

老师请问这里a去哪了，不应该取对数后变成系数么
