Abstract
Despite rapid digital growth, Indonesia faces challenges such as the digital divide. This study investigates key factors affecting sustainable digital economy development among e-commerce users, including ICT infrastructure, perceived security, perceived risk, and digital literacy. A quantitative survey of 135 urban young adults is conducted online using Likert scale questionnaires. Probability sampling facilitates data collection and analysis with SPSS. Findings reveal that ICT infrastructure, perceived security, and digital literacy significantly influence business sustainability in Indonesia, while perceived risk has no impact. This research offers valuable insights into digital economy advancement and provides a framework for future studies.
