Abstract

Public e-procurement is increasingly promoted as a means of improving transparency, efficiency, and accountability in the procurement operations of public institutions, yet its adoption in Nigerian tertiary institutions remains empirically under-examined. This study assessed the impact of digitization on the adoption of a public e-procurement portal among procurement officers, tender board committee members, and procurement department staff in eight tertiary institutions in Gombe State, Nigeria, using the Technology Acceptance Model as the theoretical framework. A descriptive survey design was adopted, and a total enumeration technique was used to draw a sample of 104 respondents. Primary data were collected using a structured, five-point Likert-scale questionnaire administered via Google Forms, yielding 104 valid responses (100% response rate). Data were analyzed using descriptive statistics, Cronbach's alpha reliability testing, Pearson correlation, and multiple/simple linear regression in SPSS version 25.0. The research instrument demonstrated high internal consistency (Cronbach's alpha = 0.835- 0.885 across constructs; overall alpha = 0.960). Regression results showed that Perceived Usefulness (β = 0.630, p < .001) and Perceived Ease of Use (β = 0.390, p < .001) jointly explained 81.9% of the variance in Attitude Towards Use; Perceived Ease of Use explained 57.8% of the variance in Perceived Usefulness (β = 0.589, p < .001); Attitude Towards Use (β = 0.513, p < .001) and Perceived Usefulness (β = 0.403, p < .001) jointly explained 83.2% of the variance in Behavioral Intention; and Behavioral Intention explained 33.2% of the variance in Actual System Use (β = 0.570, p < .001). All six hypothesized paths were supported at the 5% significance level. The findings confirm that TAM provides a robust framework for explaining e-procurement adoption in a Nigerian tertiary-education setting and indicate that usability and demonstrable usefulness are the most critical levers for sustaining adoption. The study recommends continued investment in portal usability, regular capacity-building for procurement staff, and strengthened institutional policy support, and calls for future studies to extend TAM with facilitating-condition and trust constructs.
