The research is going to make an empirical analysis of Hainan tourism image, adopting IPA analysis method. Generally speaking, there is a big gap between the Hainan tourist destination and tourists＇ expectations. The Hainan Tourist Destination image is mainly built on natural-advantage-resource projects such as natural sceneries, air quality, and climate, etc., meanwhile, the relatively insufficient constructions of soft-wares such as tourism-related facilities, as well as the quality of tourism services, etc., are the focus of future efforts.展开更多
