本文主要是在控制公司治理機制、銀行特性和國家特性的影響下，利用最小平方法調查銀行CEO或CFO過度自信與各類風險承擔程度間之關係，同時比較銀行在面對不同的經濟景氣與銀行盈損時，管理者過度自信對於銀行風險承擔行為之影響是否存有顯著不同，並期望能找出減緩管理者過度自信所可能帶來的不良影響之有效機制。研究樣本涵蓋G20與台灣的金融機構，研究期間為2005年至2012年，風險部分則包括信用風險、流動性風險、活動風險與無法清償風險。實證結果指出：管理者過度自信的確會使其銀行承擔較多的風險，不過在不同的經濟環境及盈餘情況下，也會造成不一樣的效果。銀行可藉由董事會規模的擴大來減緩過度自信管理者所帶來的負面影響，監理主管機關也可透過監理機制的強化、股東權利增強來使銀行風險程度降低。

This thesis investigates the impacts of CEO or CFO overconfidence on bank risk taking by using ordinary least squares (OLS) method under controlling the effects of corporate governance, bank-and country-specific variables. It also compares the impacts of managerial overconfidence in different economic situations and in a profit or loss situation and further seeks an effective mechanism that could mitigate the adverse effect of managerial overconfidence on bank risk taking. The sample consists of banks in G20 nations and Taiwan in the periods of 2005-2012. The risks are defined as credit risk, liquidity risk, activity risk and insolvency risk. The empirical results show that banks managed by the overconfident CEO or CFO have more risks, but there are different effects in different economic situations and in a profit or loss situation. Banks can mitigate the negative impact of managerial overconfidence by expanding the size of the board. Supervisory authorities can reduce bank risk by strengthening official supervisory power and enhancing anti-director rights.
