Research on the impact of industrial intelligence on regional green innovation performance：Based on the threshold effect of intellectual property protection

In the current global pursuit of green and sustainable development, industrial intelligence, as a new driving force for industrial upgrading and economic growth, is increasingly prominent in its impact on regional green innovation development. Based on panel data from 30 provinces in China from 2013 to 2021, this study empirically examines the impact of industrial intelligence on regional green innovation performance, and combines panel threshold models to explore the mechanism of the impact of industrial intelligence on regional green innovation performance under differences in intellectual property protection levels. Research has found that industrial intelligence has a significant promoting effect on the improvement of regional green innovation performance, and with the continuous improvement of industrial intelligence level, its driving effect on regional green innovation performance gradually increases, showing a non-linear characteristic of increasing marginal effects. Intellectual property protection not only plays a positive regulatory role in enhancing regional green innovation performance through industrial intelligence, but also shows a marginal increasing trend in its regulatory effect as the intensity of intellectual property protection increases. Regional heterogeneity analysis shows that compared with the eastern and western regions, the industrial intelligence in the central region has a more significant impact on regional green innovation performance. The research results have clarified the mechanism and impact path between industrial intelligence, intellectual property protection, and regional green innovation performance at the theoretical level, and provided theoretical reference and decision support for regional innovation entities to leverage the advantages of industrial intelligence and achieve green innovation development at a reasonable level of intellectual property protection in practice.
