Recent advancements in Digital Communication Systems and Web Technology tendered information systems cheaper and allow people to move into the electronic Government (eGov) platforms. eGov is the use of information and communication technologies (ICTs), whereas good governance refers to how well public authorities manage public and social resources. eGov supports excellent governance practices, yet it also has certain limitations. In this article, we enhance the study of Jiyuan City’s Internet-based e-government system based on an analysis of theoretical knowledge and application state. First, we gathered all government affairs platform websites; then, we built the supervision system function code in accordance with the supervision system activity diagram. Finally, the office platform's system deployment was completed, and the government office platform’s analysis environment was provided, and it was validated via experiments. The experimental results show that when there are 300 government affairs tasks to be handled, the data recall rate of the design platform’s government affairs website is 95%, and the design platform’s government affairs processing time is 15 minutes. The proposed government affairs platform has a high processing efficiency and data-carrying capacity.
