以下文章来源于海豚投研 ，作者海豚君 海豚投研 . 有灵魂的思考、有态度的研究。 来源 | 海豚投研 自4月3日美国总统特朗普正式宣布"对等关税"以来，中美之间多次互相提高关税，目前双方相互加征的关税都已在100%以上。且随着贸易摩擦 的升温，中美两国之间的角力有着进一步向其他领域扩散的风险。 值得关注的是：① 近日美国财政部长曾表示， 不排除以在美上市的中概公司强制退市，作为两国间谈判的筹码之一；② 2月21日， 白宫发布 了"America First Investment Policy"备忘录中，也提及了在一定情况下限制美国资金投资于部分中国公司/资产的可能性。 虽然上述两条潜在的风险截至目前仅停留在口头阶段，美国政府尚没有进行任何实质性的动作。但历史上，中概退市威胁并非没有先例： 2020 年~2022年间美国政府就曾以HFCAA法案下，无法获得中概上市公司的审计监管权的原因，正式推进过中概在美退市。 尽管后续中美两国政府达成了协议，中概从美股全面退市并没真正发生，但仍有中移动等公司在争端期间被美政府强制退市，后有如中国石油等 在争端缓解后仍主动选择退市。 由此可见，无论是 强制中概从美股退市、抑或禁 ...
