Why China's authoritarian regime has not failed? Scholar explain that authoritarian regime got resilience. This study focus on the influence of ideology, analysis that whether Chinese got populism and nationalism as political attitudes, and will the political support for the authoritarian regime influenced by populist nationalism? This study assumed that those who got populist nationalism might have higher political support for authoritarian regime, and it can explains why China got its authoritarian resilience. My research uses the fourth wave of Asian Barometer Survey in China. The results show that in China, the proportion of people with the value of populist nationalism is the highest, while people who got populist nationalism are those less affected by modernization. By measuring the political support of the authoritarian regime for institutional identity and political trust, find out those who have the value of populist nationalism have higher political support for institutional identity and trust of central authority institution, but they got less political trust with the actual governance institutions. It shows hierarchical political trust and the authoritarian regime remain its legitimacy from populism and nationalism ideology in China.
