E-government adoption in Cambodia: a partial least squares approach

Purpose - The purpose of this paper is to investigate factors influencing end-user acceptance and use of government administration information system (GAIS). Design/methodology/approach - A conceptual structural model of end-user acceptance and use of the GAIS was developed with technology acceptance model as a theoretical background and tested using a structural equation modeling with partial least squares (PLS) approach on a data collected from a survey among 112 public officers in 12 ministries in Cambodia. Findings - The results indicate that the factors influencing end-user adoption of the GAIS are significantly affected by perceived usefulness, relative advantage, and trust. Perceived usefulness of the GAIS is directly affected by subjective norm, image, output quality, and perceived ease of use. Practical implications - The results are of practical significance to all those interested in this area, mainly the government policy makers and practitioners in Cambodia's public services. Originality/value - The paper is the first to investigate end-user adoption of the GAIS. It is unique to Cambodia. It adds to the limited literature in e-government in Cambodia. Simultaneously, the PLS approach use in this study is quite unique with government information system research. As such, it contributes to the methodology development in the government information system research field.
