Abstract:Based on the Upper Echelons theory and Resource-Based View theory, the impact of executives' disciplinary knowledge background on firm sustainable growth, as well as its intrinsic mechanism and context of action, is empirically examined using GEM-listed companies from 2009-2021 as the research sample. The results indicate that the influence of executives’ disciplinary knowledge background on firm sustainable growth is characterized by " cross-disciplinary background > scientific background > business background > humanities background", which holds both in the data of executive teams and CEOs. The extended study finds that the interdisciplinary knowledge background of executives contributes to sustainable growth through technological innovation and business model innovation and that the influence of multidisciplinary knowledge background on sustainable development is strengthened by the background of executives who have studied abroad, which also strengthens the mediating role of technological innovation and business model innovation. The findings provide new guidelines for technology start-ups to optimize the internal configuration of their executive teams and achieve sustainable growth through dual innovation models, as well as empirical evidence for cultivating innovative executive leaders.
