Digital innovation in education: a study of e-procurement technology acceptance models

This study investigates the factors influencing school principals’ continued use of a newly launched e-procurement system in Indonesia, employing an extended Technology Acceptance Model (TAM). Based on a national survey of 3,110 middle schools and analyzed using partial least squares structural equation modeling (PLS-SEM), the findings reveal that e-procurement quality dimensions – processing, content, usability, and professionalism – significantly enhance principals’ perceptions of usefulness and ease of use, which drive continued system use. The study highlights the critical role of digital leadership capability (DLC) and school digital capacity (SDC) in shaping technology acceptance in schools, offering a novel extension to the TAM. Emphasizing human and infrastructural digital readiness, this study offers practical recommendations for improving digital governance, such as enhancing digital leadership, targeting training at procurement personnel, and strengthening school ICT infrastructure. In doing so, it contributes to ICT4D debates by providing context-specific evidence on sustaining digital public service platforms in education.
