The emergence of Information Communication Technologies(ICTs)has changed the interaction channels between government and citizens. The government has been making significant attempts to make its services and information available on the Internet. Digital empowerment is crucial to achieving sustainable development. However, digital opportunity seems to be undoubtedly an obstacle that the public faces. The study aimed to explore the use of e-government services by adopting cross-year traverse and longitudinal analysis. The study is based on a survey, entitled "Digital Opportunity of Individual/Household" from 2002 to 2018, by National Development Council. Results from the study reveal that the percentage of utilization of e-government services fluctuates between 25% to 35%. Middle-aged people, people with high education level, and the municipal people have a relatively high utilization rate. The results also indicate that digital divides exist in the citizens' ages and education levels. Persistent lower levels of connectivity among people with older and less educated. Luckily, the diffusion rates among gender and geographical/administrative areas are increasing; therefore, there is room for improving digital access as time goes by. The results of the present study help our government to develop a new policy, enhance access to technology among underprivileged groups and broaden the scope and complexity of building digital-government services, which would facilitate more effective, responsible, responsive, inclusive and participatory public governance.
