为啥不选A

NO.PZ2016010801000046

问题如下:

Which of the following is not a correct approach to calculate GDP for a given country within a given time?

选项:

A.

Sum the market value of all purchases and sales occurred in the country in that period of time.

B.

Sum the market value of all final goods and services produced in the country in that period of time.

C.

Sum all the income earned by households, companies, and government in the country in that period of time.

解释:

A is correct.

GDP can be measured with expenditure approach (B) and income approach (C). The summation of market value of all purchases and sales will double account those sales of intermediate goods.

考点:GDP核算

解析:国内生产总值可以用支出法和收入法来衡量,B和C选项正确。

但是如果把所有购进和销售的市场价值加总,就会使这些中间产品的销售重复计算。所以A选项的说法错误。

为啥不选A

嗨,努力学习的PZer你好:


为啥不选A


Hello,亲爱的同学!

GDP 衡量最终产品的价值总和才对,并不是所有产品,中间产品是不能加上的。

比如生产一台iPhone,它属于最终产品,这台iPhone的价格就可以统计进入GDP。

但是呢,这台iPhone的生产过程中,它生产了芯片、它生产了屏幕、它生产了摄像头,如果把这些中间产品的加起来,那就是重复计算了。

所以A不对。

我觉得C也不对,这几个公式都没有提到C的算法,收入法的公式也不对
