資本對於銀行經營績效之影響-以現金增資為例

摘　　要銀行資本大小代表著銀行規模大小，規模較大的銀行除了享有較高的聲譽，容易擴展業務，作為提升績效之助益，在資訊、技術共享、人力資源專業分工下，亦可降低資金成本，進而獲取更多的收益。我們從文獻回顧得知，目前大多數關於銀行產業資本的研究多以國外的資料進行實證(例如：Warner,1977；de Guevara et al.,2007；Carb’o et al., 2009；Berger and Bouwman,2009 & 2013），實證研究結果大多支持資本對於銀行績效有正向影響。本文以臺灣地區自2003年至2018年間辦理現金增資共計16家銀行合計31筆現增事件，探討的主題為透過一般民眾，以現金增資方式增加普通股，使銀行資本增加，對於金控銀與傳統銀經營績效之影響做討論與研究。銀行資本的定義分別以權益比率及資本適足率衡量之，實證結果發現：資本對於銀行績效的影響，會因衡量變數的不同而有不同的結果，若以權益比例衡量資本，在現金增資後，傳統銀行的績效比金控銀行較具顯著性。

Abstract The amount of capital on banks represent the size of banks. Besides substantial banks with an excellent reputation, it is easy to expand their business and benefit to improve performance.Under the information technology sharing and specialization for human resources, it can reduce the capital costs and get more revenue.From the related documents, we know most of research about financial service industry focused on foreign data,such as Warner(1977), de Guevara et al.(2007), Carb'o et al.(2009) and Berger and Bouwman(2009 & 2013).Most of the empirical research results support that capital hasa positive impact on bank performance,but competitiveness can be improved immediately and acquire more profits if bank capital expansion and scale increases, which may not be the case.This dissertation discusses and studiesthe impact on increasing common stocks through the seasoned equity offerings for ordinary people with 31 data from 16 banks that have handled cash replenishment from 2003 to 2018 in Taiwan.The empirical result shows the impact of capital on bank performance will be different due to the different measurement variables and the performance of traditional banks will be more significant than that of financial banks when the capital is measured by the equity ratio.
