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
是用到变形公式里的y=T*k的α次方吗,为什么是用加法呀?是根据其他答案圈出来的讲义文字就可以做加法吗,不是很理解
