In the context of healthcare digital transformation, the improvement of medical staff's digital literacy has become a key factor in improving the quality and efficiency of healthcare services. Based on the Theory of Planned Behavior (TPB), this study constructs a structural equation model (SEM) to explore the paths through which behavioral attitudes, subjective norms, perceived behavioral control, and hospital resource inputs influence the willingness of medical staff to improve digital literacy in Guilin.The results showed that: the score of medical staff's willingness to improve digital literacy was (3.90±0.70); there was a significant difference in the willingness to improve among medical staff with different age groups and education levels (P<0.05); behavioral attitudes (β=0.152), subjective norms (β=0.516), and perceived behavioral control (β=0.122) had a significant positive effect on the willingness to improve; and the subjective norms and the perceived behavioral control play a mediating role in the effect of hospital resource investment on willingness to promote.The study suggests that improving the digital literacy of healthcare workers needs to be balanced between individual belief factors and external resource support, with particular attention to the needs of low-education and young groups.
