The government then send it to all listed company to instruct them to do self-assessment, which is the first time that the Taiwan government makes all listed company to do so. In addition, the Taiwan Stock Exchange (TWSE) follows Corporate Governance Evaluation and selects 100 stocks to form The ‘TWSE Corporate Governance 100 Index’, hoping to guide the investors how to make investment on the constituent stocks, and also to encourage corporations to work on their corporate governance. This research uses Corporate Governance Evaluation and stock price, which are included in TWSE Corporate Governance 100 Index, to discuss the relevant abnormal return with event study. It is known that the company which included in the index will creates positive abnormal return and it also creates positive abnormal return to constituent stock once the news has released.
