本研究以台灣汽機車製造業之中的三家上市公司為研究對象,主要目的為探討個案公司治理評鑑結果與經營績效是否有直接關係。本研究結果發現,雖個案公司治理評鑑在前5%,但也不能直接把公司治理評鑑結果與個案公司的經營決策能力直接劃上等號,而評鑑結果落在中後段者,也並非經營獲利能力較差;公司治理機制確實能實現資訊透明,確保有效之公司治理架構並維護股東權益。此外,架構在公司治理機制上的企業董事會成員的組成,對於經營方針決策的適切性與公司治理評鑑結果並無直接正相關。本研究結論除可提供個案公司治理評鑑制度及強化公司治理實務之參考外,也可做為公司董事會內部運作之參考方針。;This study examines whether there is an association between corporate governance evaluation and financial performance for three selected listed companies in motor manufacturing industry in Taiwan. The findings indicate that firms ranking in the top 5% of corporate governance evaluation unnecessary have excellent operational and decision-making abilities. In contrast, those ranking in the latter half of governance evaluation may not have poorer financial performance. However, corporate governance mechanism does realize information transparency and ensure effective corporate governance function, thereby protecting shareholders’interests.In addition,board composition is not closely related to the appropriateness of business strategy and the corporate governance evaluation performance. The research offers suggestions to the companies examined in this study for enhancing their corporate governance evaluation and improving their corporate governance practical operation. Finally, corporate boards can take our findings as a reference for internal operation as well.
