| Summary: | 碩士 === 銘傳大學 === 經濟學系碩士班 === 95 === The study uses DEA and chooses interest expense, employee expense, constant asset and non-performing loans as input variables; interest revenue, non-interest revenue and total investment are output variables. The objective is to estimate efficiency on whole banks which are divided into two groups, including non-financial holding banks and financial holding banks in order to compare their differences in total technical efficiency, pure technical efficiency and scale efficiency. In addition, this study measures an influence on efficiency after government implemented the first stage financial reform. At last, it uses Mann-Whitney test to analyze whether managerial efficiency of banks is significant difference or not. All results are as follows:
1. China Development Industry bank, Cathay United bank, Taishin International bank, Central Trust of China and Industrial bank of Taiwan are perfect efficient banks from 2001 to 2006.
2. Except 2003, pure technical inefficiency is the main cause of inefficiency of banks within the other years.
3. Taking 2006 as an example in the slack analysis, there are 14 banks do not decrease input and increase output. These banks’ all kinds of efficiency are 1 and their input and output are optimal. They reach CCR-Efficiency.
4. Financial holding banks are better at technical efficiency, pure technical efficiency and scale efficiency than non-financial holding banks.
5. Technical efficiency, pure technical efficiency and scale efficiency in whole banks after implementing the first stage financial reform are not better than before.
