Abstract
Advancements of information and communication technologies (ICT) have made it possible for governments to shift a vast majority of their services online, creating what is known as electronic government (e-gov). Many researchers have been studying the factors influencing users' behavioural intentions to use such services. This study methodically examines and visualizes the various relationships between variables and their overall performance by reviewing the findings of 51 publications in the context of the Arab gulf countries (known as GCC countries). The study provides a holistic diagrammatic representation of the synthesized models depicting the various types and directions of relationships between variables, followed by a weight analysis of the frequently used relationships in order to determine their overall cumulative performance. The outcomes of this review contribute to theory and practice by identifying e-gov adoption research patterns and gaps and by providing recommendations to policymakers and officials involved in developing and implementing e-gov systems.
