| Abstract: | 本研究探討2018年美中關稅政策對美國企業獲利能力的影響，聚焦於電子製造服務（EMS）產業與非EMS產業。透過分析2013至2024年間168家美國上市公司的縱橫資料，針對資產報酬率（ROA）與股東權益報酬率（ROE）進行迴歸分析。結果顯示，2018年後ROA明顯下滑，反映政策整體帶來負面影響。然而，EMS與非EMS產業之間並未呈現顯著差異，顯示產業層級的政策曝險並非決定獲利下滑的主因。本研究強調企業層級的應變能力，並對政策脆弱性以產業結構劃分的假設提出質疑。
This study examines how the 2018 U.S.–China tariff policy affected the profitability of U.S. firms, focusing on Electronics Manufacturing Services (EMS) and non-EMS industries. Using panel data from 168 publicly listed firms (2013–2024), regression analysis was conducted on ROA and ROE. Results show a significant decline in ROA after 2018, indicating overall negative policy impact. However, no significant difference was found between EMS and non-EMS firms, suggesting that industry-level exposure did not determine profitability loss. The findings highlight the importance of firm-level adaptability and challenge assumptions about structural policy vulnerability. |
