美国第二季度经济增长1.5% 低于市场预期

美国商务部公布的第二季度国内生产总值首次预估数据显示，实际GDP按年率计算环比增长1.5%，不仅低于市场预期，也明显低于第一季度2.1%的增长率1。

在经济增长的驱动因素上，个人消费支出增长3.2%，拉动当季经济增长2.12个百分点1。然而，其他因素对经济形成了拖累。非住宅类固定资产投资增长8.4%，但较第一季度的10.6%有所下降1；政府消费支出和投资从第一季度的增长4.4%转为下降0.8%1。住宅类固定资产投资增长1.5%，这是连续5个季度下滑后首次实现增长1。

私人库存投资拖累当季经济增长0.67个百分点，净出口拖累幅度达1.01个百分点1，共同导致了二季度经济增速放缓。

The U.S. Department of Commerce released its preliminary estimate for second quarter gross domestic product, showing annualized growth of 1.5%, marking a deceleration from the first quarter's 2.1% expansion and falling below market expectations 1. Personal consumption expenditures provided the primary growth driver, expanding 3.2% and contributing 2.12 percentage points to overall economic growth 1.

Investment activity presented a mixed picture during the quarter. Non-residential fixed investment increased 8.4%, a slowdown from the first quarter's 10.6% gain, while residential fixed investment rose 1.5%, ending five consecutive quarters of decline 1. However, government consumption spending and investment contracted 0.8%, reversing the first quarter's 4.4% expansion 1. Additionally, private inventory investment subtracted 0.67 percentage points from growth, and net exports reduced quarterly expansion by 1.01 percentage points 1.
