| Innovations in high-tech companies are the “key to breaking the ground” for China to master basic science and technology.Intellectual property protection for high-tech firms protects the rights and interests of subjects of corporate innovation,encourages firms to engage in ongoing innovation activities,and plays a clear role in improving firm innovation performance.This paper draws on literature combing and theoretical derivation to take as an empirical sample data on the direct impact of the intellectual property protection of high-tech firms in 30 provinces,autonomous regions,and municipalities directly under the central government from 2009 to 2020 on innovation performance in China,and explores the mediating effect of R&D investment in the relationship between the two,in order to clarify the transmission path and mechanism of protection of high-tech firms’ intellectual property on innovation performance.The results of empirical research show that improving the intensity of intellectual property protection for high-tech firms can promote improved innovation performance;By improving the level of intellectual property protection for high-tech companies,R&D investments and investments in R&D personnel can be effectively promoted,and then promote the innovation performance of the firm,i.e.,R&D investment plays an intermediary role;The impact of the intensity of high-tech firms’ intellectual property protection on innovation performance varies across regions in some ways.Based on the research findings,this paper gives countermeasures and suggestions based on the real-life situation of high-tech firms: high-tech firms and relevant departments construct a good external innovation environment;Build awareness of intellectual property protection within the company;Improve the company’s internal intellectual property protection system;Develop differentiated IP protection strategies;Increase R&D investments in companies.The results of this study provide useful illumination for relevant departments of high-tech firms in formulating intellectual property protection strategies and promoting business innovation and development. |
