The first two decades of the 21st century have been marked by extraordinary transformations driven by the rapid integration of digital technologies and the relentless process of globalization, including Southeast Asia (Bertola & Teunissen, 2018; Dayley, 2019). This study, therefore, aims to assess the current state of the digital economy in Southeast Asia in 2006-2022 period. This study employs definition of digital economy of Abendin & Duan (2021). In other words, digital economy was measured by three dimensions, namely access side factors, usage side factors, and skills side factors. Principle Component Analysis (PCA) was employed to calculate digital economy index from data of 3 factors. The study finds that overall digital economy index in Southeast Asia has increased significantly in 2006-2022 period, indicating a positive trajectory towards greater digitalization. Singapore consistently leads the region with the highest digital economy score; Brunei Darussalam and Malaysia also show strong performance. Cambodia, Lao PDR, Myanmar, and Timor-Leste remain significantly behind the average index. The study reveals significant progress in Southeast Asia's digitalization journey. However, persistent disparities and emerging challenges highlight the need for continued efforts from governments, businesses, and civil society to build a more inclusive and resilient digital future for the region.
