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
老师,这道题是用图中的哪个公式呢?若是第一个的话不应该是乘法关系么?为啥题目解析里用的加。另外为什么不能用公式2呢?用产出变化率减生产力变化率减全要素生产率变动算出来为什么不行呢?
