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
为什么答案不是C???
我的解题思路跟答案一样,从数值上看,确实是X国的资本深化速度更快,Z国的技术进步为负值,其经济增长完全依赖资本深化,Z的资本深化占经济增长比重更大,再审题,题目中问的是:三个国家中哪一个国家的经济增长更依赖资本深化?应该选C啊
