The number of studies on e-government has increased rapidly in South Korea while the government has implemented world-class e-government. However, there has been little effort to assess the achievements and limitations of e-government studies up to the present. This article analyzes 146 research papers from 43 academic journals by using the meta-analysis method. Our analysis focuses on the papers' perspectives and topics, methodologies and methods, and use of theories. Comparisons to similar foreign studies are also conducted. Our finding shows that there have been substantial improvements and practical contributions of e-government research, mainly in Public Administration and Information Systems literature. Some recommendations are suggested on ways to strengthen e-government research: a multi-disciplinary approach, the rigor and diversity of research methods, theory building, salience, and plasticity.
