In the recent decade, the global retreat of democratic supportespecially among younger generations - and authoritarian diffusion becomes salient issues. In particular, the contested model of “democracy” comes into focus between the U.S. and China strategic competition. This study explores the democratic support in Taiwan, where it is often ranked as a top liberal democracy in Asia but also a frontline of the great power competition. We focus on the China factor, testing whether citizens’ evaluation on China, especially the negative impacts, is associated with people’s assessment of democracy. This study utilizes the China Impact Survey (2016) and Taiwan’s Election and Democratization Study (TEDS 2021) to examine levels of democratic support in Taiwan. In the data of 2016, I find that the China factors become significant in shaping political attitudes. People who value national sovereignty and have negative evaluation on China’s government tend to express support for democracy. Furthermore, the data of 2021 demonstrates that democratic support is significantly associated with evaluations of China and the U.S. That is, the U.S.-China competition and the fight for legitimacy between democracies and autocracies in global politics do have impacts on democratic support at the individual level.
