ABSTRACT : Recently, the term Digital Economy has been mentioned by the media and even economists as a trendy word. This study focuses on assessing the impact of the information technology (IT) industry group including IT manufacturing and IT services on a number of other industries in the economy. This study examines the relationship of the Information technology (IT) with the Vietnamese economy based on input – output analysis. The input – output table was updated by the research team for the year of 2022 with 20 industries. The research results show that the overall spillover effects of the IT manufacturing and IT service industries are both low. The final products of IT sector induced impacts little to domestic production but strongly to imports. This means that Vietnam’s IT manufacturing mainly spills over to imports. Domestic supporting products for IT production are relatively weak. The research results suggest some important macro policy implications to focus on developing the IT industry and some industries with good spillover effects to contribute to promoting Vietnam’s economic growth in the future.
