In the context of healthcare digital transformation，enhancing the digital literacy of healthcare professionals has become a key factor in improving the quality and efficiency of healthcare services. Based on the Theory of Planned Behavior（TPB），this study constructed a structural equation model（SEM）to explore influence paths of behavioral attitudes，subjective norms，perceived behavioral control，and hospital resource inputs on the willingness of healthcare professionals in Guilin to improve their digital literacy. The results showed that the mean score for willingness to improve digital literacy among medical staff was 3.90 ± 0.70. Significant differences in willingness were observed across different age groups and education levels（P＜0.05）. Behavioral attitudes，subjective norms，and perceived behavioral control all had significant positive effects on the willingness to improve. Subjective norms and the perceived behavioral control mediated the effect of hospital resource inputs on willingness to promote digital literacy. The study suggests that improving the digital literacy of healthcare professionals should consider both individual belief factors and external resource support，with particular attention to the needs of those with lower levels of educational attainment and younger groups.
