As widely known, the attraction of the Olympic game and the World Cup and successful hosting of the games must be important achievements for every government. However, more attention should be focused on the way how to utilize the sports stadiums, which astronomical fund had been invested in order to construct, after mega-sports event. Until now, we can easily find many precedents that lead the hosting country to long-term economic depression due to failure of post utilization of such stadiums, which was left as big concrete monstrosity in the city. Considering positive effects of hosting mega-sports event on national economy, we need to establish post-utilization plan before the events. From this perspectives, in this paper, I suggest three alternatives for maximization post-utilization of sports stadiums. In order to raise operating and maintenance fund, the profitability model should be established after the events. One suggestion for increasing the profit is the development of the medical tour from other countries. Other alternatives are the creation of profit through remodeling the sports facilities for Silver town, and changing the operating system of the sports facilities to a business model. The 2014 Asian Games sparked at Incheon, and will no doubt continue to stir, nationwide debate about proper resource allocation and local government, Incheon’s spending for the event. Without remove current legal restrictions which limit profitable use of the sports facilities, public sports stadiums cannot maintain its fundamental functions, such as improvement of physical service for local residents.
