认真讲 现在美国的状况跟二战前的大萧条完全不同
1929那次 是产生关税壁垒战争
因为大家争相提高关税 造成贸易紧缩 经济崩溃
但是现在各国进出口的物资差异性极大
就算提高关税 贸易影响相对较小
具体来说 看美国出口的物资
大多不是靠价格优势 要不然早就有保护
Machines, engines, pumps: US$205.8 billion (13.7% of total exports)
Electronic equipment: $169.8 billion (11.3%)
Aircraft, spacecraft: $131.1 billion (8.7%)
Vehicles: $127.1 billion (8.4%)
Oil: $106.1 billion (7.1%)
Medical, technical equipment: $83.4 billion (5.5%)
Plastics: $60.3 billion (4%)
Gems, precious metals, coins: $58.7 billion (3.9%)
Pharmaceuticals: $47.3 billion (3.1%)
Organic chemicals: $38.8 billion (2.6%)
就算美国提高关税
其他国家相应报复 影响也有限
进口也一样 iPhone加征35%的税金 还是一堆人买吧 不然要用美制的Android吗???
