A theoretical framework for key factors affecting adoption of e-procurement

We proposed a theoretical framework to identify key factors influencing e-procurement adoption. The framework combines the theory of planned behaviour and the model of technological acceptance, commonly used in B2B analyses. Through a literature review, we developed the model, drawing insights from a leading B2B e-commerce company in China. Data from 518 completed questionnaires were analysed using structural equation modelling. The study found that behavioural attitudes, subjective norms, and behavioural control are crucial for predicting e-procurement technology usage. Internal and information barriers are important for corporate clients integrating new procurement platforms. The study provides suggestions to solution providers to overcome barriers and promote electronic procurement. The paper concludes by discussing the study's limitations and future research directions.
