本研究以2003年至2011年台灣產險業為研究對象，運用資料包絡分析法(Data Envelopment Analysis，DEA)及Malmquist生產力指數，評估台灣產險業的經營效率與其生產力變動，並以Tobit迴歸模型檢測公司治理變數與資訊揭露評鑑系統與台灣產險業績營效率之關聯性。實證結果顯示台灣產險業之整體總平均總生產力變動呈現衰退現象。在公司治理變數方面，經理人持股比例、大股東持股比例、董監持股比例及資訊揭露評鑑對技術效率存在正向影響，而負債比例、成立年限及金控成員則存在反向影響。而正向影響純技術效率的有經理人持股比例、大股東持股比例、董監持股比例、資訊揭露評鑑及董事長兼總經理，反向影響的則為金控成員。大股東持股比例及董監持股比例對規模效率為正向影響，成立年限及金控成員則為反向影響。 This study adopted the sample from 2003-2011 of the property and casualty insurers in Taiwan , At first we apply Data Envelopment Analysis(DEA) and Malmquist Index to analysis the performance and productivity change for the property and casualty insurers in Taiwan. Secondly, employ a Tobit regression to analysis the effects of corporate governance and Information Disclosure on performance influence efficiency factors. The results show that the average productivity is decline. In term of the corporate governance, management ownership, largest shareholding ratio, major shareholders proportion and Information Disclosure have significantly positive effects on technical efficiency In contrast, debt ratio, the establishment of life, members of the financial holding have negative and significant effects on technical efficiency In addition, we find that management ownership, largest shareholding ratio, major shareholders proportion, Information Disclosure and CEO duality has significantly positive effects on pure technical efficiency, and members of the financial holding has negative effects on pure technical efficiency. Largest shareholding ratio, major shareholders proportion has significantly positive effects on scale efficiency and the establishment of life, members of the financial holding has negative effects on scale efficiency.
