OECD的報告：http://www.oecd.org/dataoecd/2/7/49112938.pdf
2012Q1到低點1.7%，Q2 到1.9%

請問一下美國 2011 Q4的GDP成長是多少啊?

2011Q3是2.0
2011Q4是2.5
2012Q1是1.7
2012Q2是1.9

請問報告中的GDP是YoY還是QoQ?

多謝分享
請問一下美國有沒有像我們主計處這種政府官方公布數據的機構呢??

不確定

裡頭有一句話：Real GDP growth and world trade growth (the arithmetic average of world merchandise import and export volumes) are seasonally and working-day adjusted annualised rates.

不知道這算不是YoY?

Real GDP growth and world trade growth (the arithmetic average of world merchandise import and export volumes) are seasonally and working-day adjusted annualised rates.

我也是看到這句話在遲疑.

Real GDP growth and world trade growth (the arithmetic average of world merchandise import and export volumes) are seasonally and working-day adjusted annualised rates.

剛重看了這段話,先前乎略了這兩個字.看來應該是YoY.

如果要官方數據，要看Bureau of Economic Analysis
(http://www.bea.gov/newsreleases/national/gdp/gdpnewsrelease.htm)
或這裡：http://www.bea.gov/national/an1.htm#2011AnnualRevision

不過我眼花，好像沒看到estimate在哪裡..

"seasonally and working-day adjusted annualised rates" 重點是seasonally 跟 working-day 都是adjusted 的語助詞...也就是說這是一個adjusted annulized rate(矯正過後的年度報酬率)

Real GDP growth and world trade growth (the arithmetic average of world merchandise import and export volumes)" 這麼長一句其實我們也不鳥後面那一段什麼word trade grwoth 跟用來解釋他的括糊.

所以這句話簡化之後是Real GDP growth [is] adjusted annualised rates. 也就是說他是 當季百分比 x 4 = 年度百分比 因為之前提到過的"矯正過後的年度報酬率"的其中一個矯正是季節的矯正. seasonally adjusted annaulized rate 的翻譯應是 經過年化矯正的季度報酬率.

我的結論是這句話沒講到這是QoQ或YoY GDP.

多謝 sheeplvl1 大的解釋.
你的解釋是對的.

2012F 2.0
1Q 1.7
2Q 1.9
3Q 2.2
4Q 2.3

看以上數字也知，一定是YoY
