本周四，美國商務部在第三季度GDP預測中表示，國內生產總值增長折合成年率為3.5%，遠高于之前報告的3.2%。

在第二季度1.4%的低迷增速之后，第三季度的GDP創下了2014年以來的最大增幅。

對建筑和知識產權產品的商業投資增加，鞏固了經濟基本面，因此產值也大幅提高。經濟基本面好轉促使美聯儲在上周宣布加息。

路透社調查的經濟學家曾預測，第三季度GDP增長將被上修至3.3%。

而從收入方面衡量，美國經濟增速為4.8%，而不是之前報告的5.2%。這是自2014年第二季度以來國內總收入的最快增速，在第二季度僅增長了0.7%。

約占美國經濟活動三分之二以上的消費者支出，在第三季度增長了3.0%，超出了上個月報道的2.8%。但這一速度比第二季度4.0%的增長速度依舊有所放緩。

非住宅建筑支出，包括石油與天然氣井在內，增速達到12.0%，創下了2014年第一季度以來的最快增速。之前報告的非住宅支出增速為10.1%。

出口增長預測從之前報告的10.1%，小幅向下修正為10.0%。這是自2013年第四季度以來的最快增長速度。出口增長主要反映出阿根廷與巴西大豆歉收之后，美國大豆出口的大幅增加。

上一季度，商業庫存累積速度為71億美元，而不是上個月報告的76億美元。（財富中文網）

Gross domestic product increased at a 3.5% annual rate instead of the previously reported 3.2% pace, the Commerce Department said in its third GDP estimate on Thursday.

Growth was the strongest since the third quarter of 2014 and followed the second quarter's anemic 1.4% pace.

Output was also lifted by upward revisions to business investment in structures and intellectual property products, underscoring the economy's solid fundamentals, which contributed to the Federal Reserve raising interest rates last week.

Economists polled by Reuters had expected that third-quarter GDP growth would be revised up to a 3.3% rate.

When measured from the income side, the economy grew at a 4.8% pace, instead of the previously reported 5.2% clip. That was the fastest pace of increase in gross domestic income since the second quarter of 2014 and followed a 0.7% rate of increase in the second quarter.

Consumer spending, which accounts for more than two-thirds of U.S. economic activity, increased at a 3.0% rate in the third quarter and not the 2.8% pace reported last month. That was still a slowdown from the second quarter's robust 4.0% pace.

Spending on nonresidential structures, which include oil and gas wells, increased at a 12.0% rate, the fastest pace since the first quarter of 2014. Nonresidential outlays were previously reported to have increased at a 10.1% pace.

The export growth estimate was revised a touch lower to a 10.0% rate from the previously reported 10.1% pace. It was the fastest pace since the fourth quarter of 2013. The spike in exports largely reflected a surge in soybean exports after a poor soy harvest in Argentina and Brazil.

Businesses accumulated inventories at a $7.1 billion rate in the last quarter, rather than the $7.6 billion pace reported last month.
