Intellectual property protection is a powerful support for improving the efficiency of digital industry innovation and an important point for promoting the construction of an innovative country.Using a progressive double difference model and data from listed companies in China from 2010 to 2022,this study examines the impact of intellectual property protection on innovation effi-ciency in the digital industry.The results show that:(1)intellectual property protection can positively improve the innovation effi-ciency of the digital industry,and as the innovation efficiency of the digital industry continues to improve,the positive driving effect of intellectual property protection shows a marginal increasing characteristic.(2)The mechanism test results show that intellectual property protection can promote the improvement of digital industry innovation efficiency by promoting knowledge spillover,enhan-cing technological innovation,and enhancing human capital levels.(3)The heterogeneity test results show that compared to the western and northeastern regions,the media service industry,and state-owned enterprises,intellectual property protection can better promote innovation efficiency improvement in the eastern and central regions,software development and information technolo-gy service industry,and non-state-owned digital enterprises.Based on this,it proposes countermeasures and suggestions to im-prove the intellectual property protection mechanism through multiple approaches,enhance the innovation efficiency of the digital in-dustry through multiple approaches,and promote the coordinated development of the digital industry according to local conditions,so as to to provide relevant theoretical experience for improving the innovation efficiency of the digital industry.
