A comparison of operating performance management between Taiwan banks and foreign banks based on the Meta-Hybrid DEA model

The empirical results show that: 1) the risk factor - the proportion of the total amount of overdue loans to total loans - affects the value of firms' technical efficiency. 2) From the standard deviation of the three-year average TGR between domestic and foreign banks, domestic banks reach 0.19802, which is much higher than foreign banks' 0.00388. This represents that there are great differences in average group efficiency and the technology gap ratio between foreign banks and domestic banks. 3) The operating performance of foreign banks is significantly better than domestic banks.
