E-government is the use of information and communication technologies, especially the Internet and World Wide Web, to improve the efficiency, cost and quality of the government services and information provided to its stakeholders: citizens as well as businesses, employees and other government agencies. However, despite the governments' growing investment in electronic services, at both national and local government levels, e-government research results present evidence of low-level citizen adoption of e-government services.Therefore, this book aims to discuss issues related to e-government adoption in developing countries. Particularly, this book investigates citizen adoption of e-government and explores factors affecting the level of adoption of e-government services. Importantly, this book develops a conceptual framework that is based on previous literature of Technology Acceptance Model in order to examine the relationships between certain factors (government trustworthiness, culture and perceived public value) and citizen adoption of e-government services. Target audience for this book includes students, researchers and practitioners in the field of e-government.
