摘要

金融控股公司在多角化經營下，其經營績效是否如預期般樂觀並帶來正面效益，是一個值得思考的議題。本研究採用資料包絡分析法(DEA)，探討我國金融控股公司旗下之銀行業與證券業異業結合下之經營效率與最適規模。首先以CCR模式求出總技術效率(TE)，其次藉由BCC模式求算純粹技術效率（PTE），最後再進行規模報酬分析(SE)、效率集合參考分析及差額變數分析求最適規模。
實證顯示，全體金融控股公司平均總技術效率值為0.672，意謂著金融控股公司有32.8%的投入資源沒有產生任何效益，有出現嚴重浪費投入資源與產出不足的問題。另外，本研究亦發現金融控股公司的技術無效率，有53.41%來自純技術無效率，而規模無效率，佔46.59%。且受到2008年的金融海嘯，在2008年9月，這13家金融控股公司之平均效率值為0.619，較前一季降低5.33%，可知銀行業與證券業異業結合後之金融控股公司，在面臨這一波金融危機中，其經營效率沒有如預期一樣出現合併之後的綜效。

It is a crucial topic to investigate the performance of financial holding companies with a diversified business as expected. The present study employs the data envelopment analysis (DEA) to demonstrate the operational efficiency and optimal scale under cross-industry alliance between the banking and security sectors of the domestic financial holding companies. In the first place, the CCR model is applied to obtain the technical efficiency (TE), followed by calculating the pure technical efficiency (PTE) using the BCC model. We finally obtain the optimal scale in terms of returns to scale (SE), efficiency reference and analysis and analysis of variance.
Empirically, we show that the average technical efficiency of all financial holding companies is 0.672, which implies that 32.8% of the resource fails to show efficiency and results in the serious waste of resource and an insufficient output. Furthermore, the present study also finds that the key factor giving rise to a technical inefficiency of 53.41% for financial holding companies is due to a purely technical inefficiency. The scale inefficiency, however, is accounted for 46.59%. In addition to these, under the influence of the Financial Tsunami in 2008, the average efficiency of these 13 financial holding companies is 0.619, which is 5.33% lower than that during the period of the previous season. It should be concluded, from what has been said above, that the operating efficiency of the financial holding companies after cross-industry alliance between the banking sector and security sector, does not meet the synergy of integration as expected previously as facing the financial crisis.
