Scholars at home and abroad have different views on the specific stages of e-government and the names of each stage. Professor Xu Xiaolin, an expert in public management at Huazhong University of Science and Technology, made a systematic exposition in his book The Essence of Public Management Research in China (P424-428, Wuhan Press, 2003), including four stages, five stages and six stages. There are several viewpoints in each stage of the theory.

The four-stage theory mainly includes European Commission's stage planning, IDC's stage planning, Eisenzhe's stage planning and Hong Kong's e-government stage planning. The five-stage theory, mainly represented by the United Nations and the American School of Administration (UN/USPA), holds that e-government can be roughly divided into five stages: the emergence of websites, the improvement of websites, the interaction of websites, online processing and all-round government integration.

The six-stage theory divides the development of e-government into three stages: the establishment of e-mail and local area network, cross-departmental information exchange and public access to information; Two-way information exchange stage, value transaction stage, electronic democracy stage, government inter-departmental cooperation stage, etc.
