| 摘要: | 本研究探討當企業由過度自信經理人領導時，內部人持股淨增加比率是否對公司財務績效產生正向顯著影響。研究樣本涵蓋2011年至2020年間台灣上市櫃公司共11,283筆內部人持股淨增加之交易，並依據Malmendier與Tate（2005, 2008）所提出之經理人過度投資比率衡量經理人是否過度自信，再以資產報酬率（ROA）與權益報酬率（ROE）評估公司績效。研究結果顯示，在過度自信經理人帶領下，內部人持股淨增加比率與公司財務績效之間具有更強的正向顯著關聯。此外，財務政策亦會調節此關係：當公司槓桿較低或現金流量允當比率較高時，過度自信經理人能創造更佳的績效表現。本研究強調經理人過度自信與內部交易訊號之間的交互關係，揭示財務政策如何強化或限制其對公司績效的影響。
This study investigates whether the insiders' net purchase ratio significantly impacts a firm's financial performance when overconfident CEOs lead the firm. Using a sample of 11,283 net insider purchases from Taiwan's listed companies between 2011 and 2020, we measure CEO overconfidence by employing the managerial overinvestment ratio proposed by Malmendier and Tate (2005, 2008) and assess firm performance using ROA and ROE. Our findings indicate that insiders' net purchase ratio is more strongly associated with improved financial performance in firms managed by overconfident CEOs. Furthermore, financial policies moderate this relationship; overconfident CEOs achieve better outcomes under lower leverage or a higher cash flow adequacy ratio. This study emphasizes the interaction between overconfident CEOs and insider trading signals, revealing how financial policy can amplify or constrain their effect on firm performance. |
