Abstract
Indonesia's digital economy has been driven by solid internet connectivity, widespread smartphone use, and growing e-commerce platforms. However, the digital implementation gap affects equitable access to technology and digital skills across various age groups. This research investigates factors influencing sustainable digital growth among urban e-commerce users in Indonesia, focusing on ICT infrastructure, perceived security, perceived risk, and digital literacy. A survey of 135 young adults was conducted online, with data analysed using SPSS. Findings indicate that ICT infrastructure and digital literacy significantly impacted digital economy sustainability. These insights are crucial for policymakers and stakeholders aiming for inclusive digital economic development.
