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
题目问的是哪个国家更依赖capital deepening来获得经济增长,解题算的是哪个国家capital deepening增长率更高,这两者之间是正相关吗?为什么不能用capital deepening再除以GDP growth rate来计算呢?
