我今年大一，学校布置的宏观作业要求我们找从2004到2014美国和英国的经济增长数据……这个倒没什么
但是要求我们把Real GDP growth rate 的数据和Consumption Investment, Govt Spending, net exports这些的数据也找到并进行对比我就蒙蔽了。。。请问这些component每年的数据到哪里能找？还是要自己通过其他的indicator计算啊？

Collect data for gross domestic product (GDP) and aggregate demand (AD) components
for the period 2007-2014 for (only) two economies from the following list:
1. United Kingdom
2. United States
3. Germany
4. Spain
Describe the contributions and dierences in the role of the AD components to GDP
growth during this period. What might explain the dierences seen in the role of con-
sumption and investment during the period considered?



这是题目。。。求大神帮忙T-T-我找了一个下午了还是找不到想要的数据
