Abstract: Tourism industry is one of the industries most correlated with the Expo. An interactive correlation has been shaped between World Expos and the tourist industry: on one hand, keeping stable and consistent in-flow of tourists indicates the success or failure of each Expo, tourist industry plays an important role in realizing the values of all kinds of resources contained in World Expos; on the other hand, the introduction of huge in-flow of tourists from both home and abroad by each World Expo provides an impetus to host city reconstruction and hard-won development opportunity. World Expo is sure to have evident post Expo effects, besides, the post effects are often bigger than the investment pull effects at the preparation period and the demand pull effects at the exhibiting period. During the post World Expo period, tourism effects mainly consist of tourism brand effects, environmental effects, resource effects, radiation effects, magnifying effect and valley effect. Therefore, proper development strategies should be adopted in such areas as tourism promotion, resource follow-up utilization, regional tourism cooperation, upgrade of tourism industry, and so on, so as to explore and give full play to the tourism effects during the post World Expo period.

Key words: post-Expo era; MICE; tourism effects; Shanghai World Expo
