The Impact of Generative AI Use on Graduate Students’ Research Competence: The Mediating Role of Critical Thinking and the Moderating Role of Research Self-Efficacy

Abstract

With the development of the digital intelligence era, generative AI is being widely used in scientific research, and its impact on graduate students' research competence has attracted much attention from the academic community. Based on cognitive distribution theory and self-efficacy theory, this study classifies AI applications into three levels from basic to advanced-technical support AI use, text development AI use, and transformation AI use-explores their effects on graduate students' research competence, and examines the mediating effect of critical thinking and the moderating effect of research self-efficacy. The results of the empirical analysis show that all three types of AI use behaviors are significantly correlated with research competence, with the strongest correlation for text development type and the weakest for technical support type. In the relationship between the three types of AI use behaviors and research competence, critical thinking plays a significant positive mediating role, and research self-efficacy plays a significant moderating role. Universities and tutors should guide students to focus on higher-order AI use behaviors in the text development and transformation categories, promoting the use of critical thinking to avoid technology misuse and improving research self-efficacy to help students accumulate confidence and support their research.
