So far, foreign studies on how political uncertainty affects corporate investment and financing decisions have been abundant. However, the impact of politics on the economy varies from place to place. Taiwanese political activities not only affect domestic economic policies, but also affect cross-strait relations. This study wants to explore whether the political uncertainty caused by Taiwanese election activities will affect the capital structure of Taiwanese enterprises, and is divided into a control group and an experimental group based on whether the enterprises invests in China. Analyze whether companies investing in China have reduced debt financing. According to the results, after the election year, the increase in corporate financing costs is consistent with our hypothesis. However, in the case of rising borrowing costs, some companies investing in China have increased their debt financing. In addition, this study finds that after the election in 2004, companies that have invested in mainland China have significantly increased their return on assets (ROA) and profit and loss on investment in China.政治不確定性選舉不確定性資本結構融資成本大陸投資Political uncertaintyElection uncertaintyCapital structureFinancing costInvestment in China
