Abstract
<p><big>Based on provincial panel data from 1998-2018, this paper estimates research and development (R&amp;D) factors, and a stochastic frontier analysis (SFA) model is constructed to examine the effects of R&amp;D factors on regional total factor productivity (TFP). The results show that both R&amp;D capital stock and R&amp;D personnel can significantly promote regional TFP, but the productivity-enhancing effect of R&amp;D factors is different between regions. Specifically, R&amp;D capital and R&amp;D personnel can promote TFP in eastern and central provinces, and the promotion effect is not significant in western provinces. In addition, compared with investment-driven regions, innovation-driven regions are more likely to enhance TFP by R&amp;D factors.</big></p>
