【#先声夺人# ｜关税之下：美国再次对华加征关税，历史教训警示贸易保护主义风险】美国执意以芬太尼问题为由, 再次对中国输美产品加征10%关税。中方斥责此举系"恩将仇报"并迅速反制，宣布自3月10日起对美部分商品加征关税并采取非关税措施。美国经济学家警告，加税将推高物价、削弱贸易，损害美国经济。约翰霍普金斯大学教授史蒂夫·汉克指出，1930年《斯穆特-霍利关税法案》曾导致美国进口锐减70%，加剧了大萧条。彼得森研究所研究员杰弗瑞·肖特表示，美国政府不得不在1934年颁布《互惠贸易协定法》，通过削减关税谈判来扭转局面、缓解危机。如今，美国再次采取单边关税措施，试图通过贸易保护主义手段解决问题，却可能重蹈覆辙，最终伤及自身。The U.S. is citing the fentanyl issue as a pretext to impose an additional 10 percent tariff on Chinese imports. China condemned this as "repayment of kindness with hostility" and retaliated by increasing tariffs on U.S. goods and implementing non-tariff measures starting March 10. American economists warn that these tariffs will backfire. Historically, the Smoot-Hawley Tariff Act of 1930 led to a 70 percent drop in U.S. imports and exacerbated the Great Depression. The U.S. later enacted the Reciprocal Tariff Act of 1934 to reduce tariffs and ease the crisis.
