Since winning the right to host the 2009 World Games in June 2004, Taiwan has been making numerous preparations for the big event. During the preparation period, intense preparations and the support of human resource as well as material resource are essential. However, Taiwan is currently lacking of experienced organizations on hosting large-scale international sports events and un-unified affair right. The promotion of the central policy rarely takes into account the diverse local public opinion over an extended period of time, which causes the inappropriate resource allocation for local development. The preparation is full of difficulties because the central and local resources could not bring out the full beneficial result. This research aims to analyze the 2009 World Games pre-events by using the data and literature review analysis. It does not only improve the hardware and software of city¡¦s structure. It also offers the opportunity for citizens to interact with various cultures. The most important thing is increasing the centripetal force of the people in a short time and promoting Taiwan into the international stage. The key factor is the marketing tactics brought out by the sports event, which expresses concretely the cultural integration, united harmony and state consciousness of Taiwan. The marketing tactics brought out by sports event pushes the rapid development of the city appearance, creative and artistic livelihood, and sustainable environment and tourism industries. We hope to drive the economic development by hosting large-scale sports event. Our goal is to promote the city and show the vitality of entire city. The global participative sports event will bring the long-term benefit for the city economy. Kaohsiung should work harder in the future, striving actively for the right to host international event which helps internationalize the city, expand commercial possibilities, and gain people recognition.
