On 21 August 2019, Hsu was elected chairman of the New Power Party by a 7–5 vote of its executive council.

Despite Kuomintang opposition, Hsu and the New Power Party moved to abolish the Red Cross Society Act of the Republic of China in July 2016.

Hsu joined the New Power Party on 21 June 2015, after failing to secure a legislative nomination in the Taichung area from the Democratic Progressive Party. Hsu was named a deputy leader of the NPP on 13 September 2015, and stepped down from that position in March 2016. He serves the party within the Legislative Yuan as its first caucus whip.

Citing survey data from the Mainlander Taiwanese Association, Hsu opined in 2005 that differing views of the 228 Incident are no longer an ethnic issue, but instead a cross-party conflict. He has criticized the Kuomintang and People First Party’s electoral strategy in the 2000 presidential elections, comparing it to the Democratic Party’s loss in the United States presidential elections held that same year. Shortly after the 2006 protests led by Shih Ming-teh, Hsu wrote that the proposed formation of a third presidential ticket in the 2008 election would have taken more votes from the Democratic Progressive Party, leading to an easy Kuomintang victory. The KMT won that election without the materialization of a third-party candidate.

Hsu earned his doctoral degree in political science from the University of Michigan in 1999 before beginning his teaching career at National Chung Cheng University. In the mid-2000s, Hsu was a political analyst and research fellow at Academia Sinica’s Research Center for Humanities and Social Sciences. He later joined the faculty of Soochow University, where he taught political science, and served as director of the Taiwan Brain Trust think tank.
