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%
請問爲何不是(170/120)-1? 最後也≈41%,謝謝
