本研究主要目的為檢視銀行業的多角化對於經營效率的影響，此外也會分別就金融控股公司及獨立董事之兼任問題進行探討。許多文獻基於不同理論和模式，均已指出多角化與成立金融控股公司對公司績效的好處和壞處,其中綜效及風險降低為主要的正向理由，而負向影響則多基於代理問題、資源分散與低競爭力等論點。獨立董事在董事會中扮演著獨立監督公司經營者的角色，由於其監督影響力及與市場的連結，有助減緩股東和經理人間的資訊不對稱問題。尤其甚者，獨立董事可以就其專業背景對於公司的投資與經營決策提供良好建議，而可能降低多角化的負面影響。因此多角化、金融控股公司、獨立董事兼任問題與銀行經營效率之間的關係實為一值得瞭解及深究的議題。
我們將採用資料包絡分析法 (DEA) 進行實證研究，計算出國內銀行的相對效率值，再利用 Tobit 迴歸分析多角化、金融控股公司以及獨立董事忙綠程度與經營效率之間的關聯性。研究結果顯示，多角化對於銀行的經營效率呈現顯著的負相關，顯示了銀行的多角化不僅不會使得銀行的經營效率提升，反而會造成反效果；金融控股公司與獨立董事忙碌程度對於銀行的經營效率呈現顯著的正相關，顯示出了成立金融控股公司及兼任多職的獨立董事，對於提升營行的經營效率皆有正面助益。

This study examines the impact of diversification on the efficiency of banking firms, with the consideration of the issue regarding financial holding companies and busy directors. Based on previous theories and models, numerous researchers have pointed out effects coming from both the bright side and dark side attributed to diversification. The most positive impacts result from Synergy and risk reduction while negative ones are agency problems and the lack of competitiveness. Hence, it is critical to understand the relation within institutional ownership, diversification and performance.
We employed Data Envelope Analysis (DEA), which is a nonparametric method and well-documented in evaluating performance of banking firms, to capture the efficiency of bank performance. We further use Tobit Model to construct the connection within diversification, financial holding company and busy independent directors. The result shows that bank’s diversification is negatively related to performance. On the contrary, financial holding companies and busy independent directors is positive related to performance.
