用(170-120)/120再减1得出来的数不就是增长率嘛?

NO.PZ2018062003000089

问题如下:

Last year, the annual value of final goods and services of country. A increased from $200 billion to $400 billion, the GDP deflator increased from 120 to 170. In this condition, the real GDP of country A increased by:

选项:

A.

35%.

B.

41%.

C.

52%.

解释:

B is correct.

Real GDP in the year before last was: $200/1.2= $167

Real GDP in the last year was: $400/1.7= $235

($235- $167)/$167=41%

考点: GDP deflator

解析:运用 GDP deflator 反解出一年前后的真实GDP数值,

一年前:$200/1.2= $167

一年后:$400/1.7= $235

在进一步求得真实GDP的增长率,($235- $167)/$167=41%

用(170-120)/120再减1得出来的数不就是增长率嘛?

嗨,从没放弃的小努力你好:


用(170-120)/120再减1得出来的数不就是增长率嘛?


是的,理解正确,用(170-120)/120就是增长率。


但是,都是增长率,要搞清楚,是什么项目的增长率。


用(170-120)/120,是GDP deflator的增长率。


但是本题问的是real GDP的增长率,但没有问GDP deflator的增长率


real GDP = 名义GDP/GDP deflatior
