Mobile and wireless technologies (MWTs), such as wireless laptop computers, personal digital assistants (PDA), mobile phones, smart phones, etc., have deeply penetrated our lives. Government agencies use MWTs to enhance their managerial effectiveness and provide high-level services to citizens taking advantage of its characteristics of mobility, ubiquity, provision of other location-based government services, and on-time information delivery. Mobile government (m- Government) is forming diversely within (as well as between) different countries. China currently has 738.57 million mobile phone users and 29 cities are deploying “Wireless City” projects. Within this context, we chose six different cities in China to examine m-Government maturity and assess the deployment of m-Government services. We further explored mobile and wireless technology (MWT) application and implications in conjunction with a special project in Beijing. Results are discussed and conclusions are drawn.
