The financial memorandum of understanding (MOU) signed by Taiwan and the Mainland China on November 2009 is an important agreement because it’s the first time for the government of China to allow Taiwan’s banking industry to operate in China. This paper uses event study to examine whether MOU would affect the cumulative abnormal returns (CAR) of banking securities listed on Taiwan Stock Exchange (TSE) and Over-the-Counter (OTC) market. The results are as follows: (1) During the window dates, sample companies had a significant positive CAR. (2) The relationship between CAR and sample companies’ ROA is positive. (3) The relationship between CAR and the number of representative offices established by the sample companies is positive. (4) Bank’s size has no significant relationship with CAR.622252 bytesapplication/pdfen-US事件研究法金融合作備忘錄MOU累積異常報酬率Event StudyCumulative Abnormal ReturnsRepresentative Officesthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/257610/1/ntu-100-R98722035-1.pdf
