How does multidimensional R&D investment affect green innovation? Evidence from China

Under the background of green development, multidimensional R&D investment and institutional quality have injected strong power into green innovation. Based on China's provincial panel data from 2009 to 2018, this study examines the threshold effect of R&D and R&D personnel input on China's green innovation capability from three perspectives, namely, political institutional quality, economic institutional quality, and legal institutional quality. The core study results show that the influence of R&D on China's green innovation capability has an obvious double-threshold effect based on institutional quality. This study expands the research on the influencing factors of green innovation and the influence effect of multidimensional R&D investment and provides a theoretical basis for regional green innovation management. In addition, the research results of this study provide a reference for accurately formulating regional green innovation capability promotion strategies.
