Stimulating enterprise innovation is an important way for the state to promote economic development and social progress.Using data from listed manufacturing companies on the Shanghai and Shenzhen stock ex-changes in China from 2010 to 2022,this paper analyzes the impact mechanism of R&D subsidies and intellec-tual property protection on enterprise independent innovation inputs and empirically tests the relationship be-tween government R&D subsidies,intellectual property protection,and enterprise independent innovation in-puts.The study finds that R&D subsidies exert a suppressive effect on enterprise independent innovation in-puts,while intellectual property protection exerts an incentive effect.At the same time,R&D subsidies and intellectual property protection have an interactive effect on enterprise independent innovation inputs,and the level of intellectual property protection can weaken the suppressive effect of R&D subsidies on enterprise inde-pendent innovation inputs.The heterogeneity analysis shows that the suppression effect of R&D subsidies on enterprise independent innovation inputs is stronger in state-owned enterprises and enterprises with weaker market competition,while the incentive effect of intellectual property protection is stronger in non-state-owned enterprises and enterprises with stronger market competition.Further research reveals that R&D subsidies can only promote the quantity of enterprise innovation output,while intellectual property protection can improve the quality of enterprise innovation output and incentivize substantive innovation,which indicates that the inhibito-ry effect of R&D subsidies on enterprise autonomous innovation input is the key factor causing enterprises to prioritize innovation output"quantity"over"quality".
