Purpose: Drawing on familiar concepts such as inclusive leadership and organizational support theories, and the input-mediator-output-input model, this study aims to explore civil servants’ intention towards digital transformation adoption in the public sector of Vietnam. Method: This study takes the form of a case study of the Vietnam context and employs a quantitative method. A printed questionnaire was distributed to collect data from 892 civil servants. After excluding cases with missing data, 863 valid cases were used for data analysis. Primary data analysis was conducted using SPSS 20, Amos 20, and SMARTPLS version 4, which included descriptive statistics, testing the proposed model and hypotheses using the SEM approach, and conducting the importance-performance map analysis. Findings: The current study revealed that inclusive leadership, government support, and organisational support have both direct and indirect effects on the intention towards digital transformation adoption through the partial mediating role of organisational innovative climate. Moreover, the importance-performance map analysis revealed that while organisational support is the most important factor, it has the lowest performance. Originality: This study is pioneering in its use of the IMOI model to predict intentions towards technology adoption, particularly in the context of digital transformation, a new aspect in developing nations, including Vietnam. The study contributes to our understanding of digital transformation adoption in the public sector and will be of particular interest to government, policymakers, and service providers of new technology systems.
