Providing a balanced account of government performance under Tsai’s Ing-wen’s reign, chapters in this edited volume combine theory and extensive empirical data to highlight both achievements and shortfalls of her administration. Chapters range comprehensively from topics of the implementation of same-sex marriage, curriculum reform, ‘transitional justice’, industrial policy and pension reform, which have been celebrated by domestic Tsai Ing-wen supporters, but have also met with considerable opposition from within Taiwanese society. Externally, cross-strait relations, the New Southbound Policy and the triangular relationship with China and the USA, which embodied major challenges for Tsai’s first administration, are also analysed as key reference points throughout. Featuring contributions from twenty six internationally renowned Taiwan scholars, is an essential resource for students and scholars of Taiwanese politics and society, cross-strait relations and international relations.
