The objective of this study is to explore the curvilinear relationship between innovation and sustainable firm growth, as well as the moderating role of bank funding on R&D, institutional quality and bank market power on this nexus. To do this, we selected a sample of 424 companies over the period 2010-2022. Using a systemic GMM model, the results show that there is a curvilinear (inverted U-shaped) link between innovation and sustainable firm growth. In addition, the outcome shows that bank funding on R&D, institutional quality and bank market power moderate the curvilinear nexus between innovation and sustainable business growth. This study offers valuable insights for strategic innovation planning and elaboration of important implications by highlighting the role of bank funding on R&D, institutional quality and the power of the banking market in promoting firm sustainability.
