继2025年底的疲软表现后，美国制造业产值在第一季度反弹，且增长扩大到人工智能领域以外。

　　美联储周四公布的数据显示，剔除计算机和半导体等高科技产业后，制造业产值折合年率增长2.8%。这是2021年以来最为强劲的增速之一，当时经济正从疫情中恢复。

　　美联储的数据显示，机械、汽车、矿产品和电气设备等行业均在第一季度实现大幅产出增长。

　　尽管伊朗战争推高投入成本给制造商带来新的不确定性，但制造业显现出复苏的苗头。随着贸易政策不确定性缓解，以及企业利用有利税收政策，资本支出今年可能保持强劲。

　　3月制造业产值下降0.1%，主要受汽车生产疲软拖累。剔除汽车后，制造业产值小幅增长0.1%，为连续第三个月上涨。
