本研究主要係探討2015年至2016年期間政府針對勞動基準法多次進行修改，對於航運類股股價的影響。本研究採用事件研究法來分析2016年勞基法歷經多次的修正，各法令修正時期對於航運類股是否產生顯著的異常報酬，資料來自台灣經濟新報資料庫(TEJ)，擷取自2010年至2020年，共計10年的時間19檔台灣證交所上市航運類股。研究結果顯示:在勞動基準法修正案尚在草擬階段時期，宣告期間之異常報酬表現並不顯著，直至由立法院三讀通過勞動基準法修正案宣告後，宣告日前後十天產生了顯著的負向異常報酬及累積異常報酬，表示航運類股投資人對於該法案通過是給予負面評價的。 The present study explores the effect of the government’s multiple amendments to the Labor Standard Act during 2015 and 2016 on the stock prices of freight shipping companies. This study uses the event study method to analyze whether the multiple amendments to the Labor Standard Act in 2016 resulted in significant abnormal returns on freight shipping stocks and collect data from the 2010–2020 database of Taiwan Economic Journal. Sample data from the 10-year period comprise 19 freight shipping stocks listed on Taiwan Stock Exchange. The research results revealed that abnormal returns are not significant during the drafting phase of the Labor Standard Act amendments. Significant negative and cumulative abnormal returns are observed 10 days before and after the promulgation of the Labor Standard Act amendments following the Legislative Yuan’s passing of the third reading on the amendments, suggesting that investors of the freight shipping stocks held a negative view of the amendment to Labor Standard Act.
