Abstract

The hybrid DEA model can solve the difference between radial inputs and non-radial inputs and evaluate efficiency. This is a pioneering study that uses the hybrid DEA model, evaluating the proportionate inputs with a radial measure and the non-proportionate inputs with a non-radial measure, in order to examine the impact of non-performing loans (NPLs) on the efficiency of Taiwan's banking sector from 2006 to 2010. In summary, this research demonstrates the following: (1) Only nine banks remained in the top efficiency list during these years: China Development Industrial Bank, Mega International Commercial Bank, Chinatrust Commercial Bank, Cathay United Bank, Bank of Kaohsiung, Industrial Bank of Taiwan, Taiwan Cooperative Bank, Land Bank, and Bank of Taiwan. (2) Risk is an important factor that should be taken into consideration when evaluating banking efficiency. (3) From the hybrid DEA model, we find that most of the inefficient banks have an inefficiency factor caused primarily by too many NPLs (risk). (4) The efficiency of Taiwan's large-scale banks is significantly better than the small-scale bank. By looking at the inefficiency index, the large-scale bank's inefficiency is caused by NPLs. For the small-scale bank, both radial variables and non-radial variables have equal importance in improving its efficiency.
