Via quantitative analysis and interviews, this article examines the credibility and sustainability of Beijing’s patronage policy towards Taiwanese business. The new finding is that the rise of economic nationalism and local protectionism in China is undermining and constraining Beijing’s patronage policy. Consequently, China’s rising economy does not deepen cross-Strait integration but rather crowds out Taiwanese business. Moreover, considering the growing influence of Chinese domestic constraints, this article attempts to provide a bilateral two-level game to grasp the new dynamics on cross-Strait relations under the new normal.
