Abstract
How do graduate students perceive the quality of digital education? With considering the characters of postgraduates, this research examined the mediating role of academic self-efficacy and the moderating effect of digital literacy in the basic model. A survey of 1,256 graduate students in the southwestern region of China was conducted, and structural equation modeling and curve fitting were adopted for mechanism analysis.The research found that the level of digitization in higher education institutions affects postgraduate students' perception of academic self-efficacy, which in turn influences their perceived education quality. Furthermore, in digital education within higher education institutions, postgraduate students with high digital literacy perceive higher perceived education quality compared to those with low digital literacy. The relationship between digital technology and postgraduate students' perceived education quality is not linearly increasing, but rather follows a steep and then smooth upward curve.
