Abstract:
The aim of this study was to fill the knowledge gap through assessing the influence
of relative advantage towards e-procurement adoption in developing countries, Tanzania in
particular. The study adopted positivism philosophy and cross-sectional survey research
design. The study also used stratified sampling technique. Sample size was 157.
Questionnaires and documentary review were used for data collection. The collected data
were analysed by using Partial Least Squares Structural Equation Modelling with the help of
SmartPLS 3 software. Findings reveal that in the presence of attitude, relative advantage has
direct and indirect influences towards e-procurement adoption. Grounding on the theoretical
and empirical gaps, the hypothesized relationships of the determinants of new technology
(relative advantage and attitude) have therefore filled these gaps which leads to the
theoretical, empirical and practical contributions.The study recommends attention to be paid
for relative advantage towards e-procurement adoption in Tanzania and in all developing
countries which intend to adopt new technologies in public sector
