The Electronic Government (E-Government) is via the information network systems, connecting the government agencies, the citizen, and the information, establishing a real-time interactive system, which leads to the convenient and faster access to government information and services, making the convenient services to the citizen a reality. Based on the E-Commerce application models, there are four types of E-Government. They are Government to Citizen (G2C), Government to Business (G2B), Government to Government (G2G) and Government to Employee (G2E). The purpose of the G2G application model is to establish the information exchanges and integration application among the agencies so that the government can provide faster and convenient services to the citizen. This study uses the property management of the lands owned by the City of Kaohsiung as an example. The property management agency of Kaohsiung municipal government desperately needs the shared information provided by other agencies to resolve the complicated issues of property management. However, the municipal government does not have a standard process for the agencies to follow. If the negotiation between the information supplier and information consumer falls through, or there is no negotiation channel at all, the information cannot be shared among the agencies. Currently because of the following reasons: (1) no central mechanism in charge of the planning and management of the whole information business for the municipal government, (2) self-centered and conservative attitude of the agencies which own the information, (3) no mechanism for negotiation and assessment, (4) no sufficient budget and man power, the information integration and resources circulation is not a reality just yet. The municipal government does not take advantage of the available Internet resources and, therefore it is not able to provide the services of better quality to the people. In the continuing development stages of the E-Government, information sharing and integration application is the goal for the current important administration overhaul of the government. How to effectively execute information sharing among the government agencies is, as a matter of fact, the centerpiece of this study. The purpose of this study is through the exploration of shorter work flow due to the land information management and the current inter-agencies information sharing integration services, to provide an innovative thinking direction, hoping the execution can achieve the following: (1) Establish a standard work flow for the operation of information sharing among the municipal government agencies so that the information supplier and consumer agencies can follow. (2) Speed up the information sharing and messages circulation among the municipal agencies; simplify the internal administrative procedures of the agencies reaching the goal of efficiency and effectiveness of the services to citizen. Through the in-depth interviews, research, and analysis, there are some findings. To have information sharing among the government agencies, these need to be done: (1) set up a commission for propelling information sharing, (2) implement a standard work flow of information sharing for the City of Kaohsiung, (3) build up a mechanism for the inter-agencies negotiation. These conclusions will integrate the service flows of different agencies, making the execution of E-Government closer to a reality.
