Abstract

Purpose This study aims to investigate and comprehend the key factors that affect citizens’ adoption of electronic government (e-government) in Nigeria. In addition, the exploration intends to assess the potential determinants that may affect the Nigerian’s behavioural intention (BI) to adopt e-government services. The findings can be helpful for policymakers and government officials to provide e-government practices effectively. Design/methodology/approach The research adopted a quantitative method using the unified model of e-government adoption (UMEGA). In this study, data are collected from 410 citizens aged above 18 years old and analysed using partial least squares path modelling technique. Findings The results showed that performance expectancy and effort expectancy positively influenced attitude (ATT) towards e-government. In contrast, perceived risk negatively impacted ATT towards e-government. However, social influence did not have a significant influence. The results showed that ATT and facilitating conditions (FC) positively influenced the BI to use e-government services. The explanatory and predictive power of UMEGA in Nigeria accounted for 63.9%. Originality/value To the authors’ knowledge, no prior studies analysed citizens’ adoption of e-government in Nigeria. This study, however, filled this gap. This study has contributed to the current knowledge of e-government adoption in Nigeria, which policymakers and government officials can use.
