IMPACT OF ELECTRONIC PROCUREMENT PRACTICES ON THE SUPPLY CHAIN PERFORMANCE OF LISTED CONSTRUCTION COMPANIES IN NIGERIA

Abstract

Electronic procurement has emerged as a critical tool for enhancing supply chain performance, particularly in the construction industry, where procurement inefficiencies often undermine operational efficiency. This study examines the impact of electronic procurement practicesspecifically electronic sourcing, electronic tendering, electronic ordering, and electronic invoicing, on the supply chain performance of listed construction companies in Nigeria. Guided by Transaction Cost Theory and Resource-Based View, the study employs a quantitative research design, collecting secondary data from annual reports, procurement databases, and industry records spanning 2014-2023. Data analysis was conducted using structural equation modeling (SEM) to evaluate the relationships between electronic procurement practices and supply chain outcomes. Findings reveal that all dimensions of electronic procurement exert positive and statistically significant effects on supply chain performance, with electronic ordering exhibiting the strongest impact. The study concludes that digital procurement technologies enhance operational efficiency, reduce procurement cycle times, improve transparency, and strengthen supplier collaboration. Recommendations include increased investment in digital procurement infrastructure, standardization of electronic tendering, staff training, and government support for digital transformation. The study contributes to procurement and supply chain literature by providing empirical evidence of the effectiveness of electronic procurement practices within the Nigerian construction sector
