Abstract To integrate the operating ability and to enhance the operating efficiency of financial institutions, the government of Taiwan promulgated the act of financial holding company in June 2001. Fourteen licenses of financial holding company have been issued since then and the purpose of forming financial holding companies is to increase their international competitiveness which is important to Taiwan since she has become a member of WTO. Among those 14 financial holding companies they are different in scales, in operating strategies and in operating performances. Can those small-scaled financial holding companies survive in the market with increasing competitiveness? Should they merge with other large scaled financial holding companies? The purposes of this thesis are to analyze the previous two questions. In other words, we examine the impact of the Act on the operating strategy and performance of two small-scaled financial holding companies: Jin Sun and Waterland financial holding companies. To address the second issue mentioned previously, we also analyze the operating strategies and performances of the Fubon financial holding company, which is known as having the advantage of stores and branches and of marketing financial products. Our research provides critical operating strategies for Jin Sun and Waterland financial holding companies to enhance their operating performances.
