ABSTRACT
This study aimed at filling the theoretical and empirical knowledge gaps regarding the debate on determinants of e-Procurement adoption model for green procurement using UTAUT and TOE model. Positivism philosophy and cross-sectional survey research design were adopted. The study also used purposive and stratified sampling techniques. Sample size was 157 respondents. 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. Finally, an integrated e-Procurement adoption model for green procurement was validated of which legal framework and relative advantage seem to have indirect influences towards e-Procurement adoption system. However, performance expectancy has direct and indirect influences towards e-Procurement adoption system. Above all, attitude has direct influence towards e-Procurement adoption system. The study has significant contribution in terms of filling the theoretical and empirical knowledge gaps. This would have practical implications in terms of public procurement policy implementation and applicability of e-procurement in the public sector for developing countries, Tanzania in particular. The model can be used by the Government leaders and policy makers as a framework of analysis for decision making. This study would help other future researchers to use the final integrated model in the process of adding new knowledge to the existing literature when conducting researches related to buyer-supplier perspectives.
