International digital talents are critical strategic resources for countries to improve their comprehensive national power and global competitiveness. To better respond to the challenges of economic globalization, it is essential to deepen the reform of the international digital talent training system, clarify the development direction of international digital talent training, and build an international digital talent training mechanism. Based on the grounded theory, the study constructs a global digital talent education system model with three core categories of “input-process-output” and seven main categories through three-level coding and selects 200 data for analysis. The study results show that the current international digital talent education mechanism is imperfect, and the quality of talent is low; the teaching technology, teacher quality and social resources are poor. At the same time, the study proposes countermeasures and suggestions for the weak links from three levels: input elements, process elements and output elementsproviding some theoretical guidance for the school to cultivate better talents.
