After more than a decade of research in the field of e-government, it is now timely and appropriate to reflect upon the overall developmental directions in the area. The purpose of this paper is to explore research progress to date by systematically analysing the existing body of knowledge on e-government related issues. Usable data relating to e-government research currently available were collected from 434 research articles. Based on the investigation of the various studies, our findings reveal that survey was the most utilised research method, and the Technology Acceptance Model was the most utilised theory to explain research models. Although a large number of theories and theoretical constructs were borrowed from the reference disciplines, their exploitation by e-government researchers appears largely random in approach. The paper also presents limitations and further research directions.
