E-government applications have become an important interface between citizens and public administration. However, quantitativeresearch on e-government usage shows a tendency toward generic research models and in part lacks statistical rigor. Especially mediating conditions are often not taken into account appropriately. This contribution addresses this gap and provides a conceptually extended model of technology acceptance in the context of online city portals. The proposed model is tested with a large sample (n = 1,273) using structural equation modeling. Ease of use, usefulness, and privacy were found to be determinants of e-government portal acceptance, which in turn determines continuance intention of e-government portals. Furthermore, Internet competence and need for personal interaction were found to be direct determinants of continuance intention on the level of individual user appeal. The findings are discussed in terms of theory, and implications for public managers of online city portals are derived.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
