Question

请教一道英文的求GDP的宏观经济题目，非常感谢

题目是这样的：item:wages paid to labour;households'financial consumption expenditure;exports;government transfer payments;private gross fixed capital;rent for land; consumption of fixed capital; imports;government expenditures;personal taxes;firms'profits.
a:calculate GDP using the expenditure approach
b:calculate net investment
对于A题，公式是：Y=C+I+G+X-M。 C代表consumption expenditure;I代表invest expenditure;G代表government expenditure;X代表export;M代表import.我是不知道ITEM的那些项都是对应公式里的哪项，请讲解。
对于B题， 我知道净投资等于总投资减去折旧，可是我还是不知道ITEM里的哪项是总投资，哪项是折旧。

Answer 1

第一，GDP 宏观角度有三个sector.household,firm and government

A 题是我认为， 首先 Y=收入=消费=value added。
如果是从expenditure approach 算的话，那就应该是个人消费+公司消费+政府消费+税收+出口-进口。households'financial consumption expenditure+government expenditures+government expenditures+consumption of fixed capital+personal taxes+X-I。

B题呢我觉得是，firms'profits-rent for land

但是说实话，这两道题做的我有点儿越答越蒙，你就参考一下吧。肯定不十分准确。
