Tourism, a major item of services exports, is one of the industries processing great potential for development in 21(superscript st) century. Nearly all governments therefore dedicate themselves to increasing tourism attractiveness to stimulate economic growth, and Taiwan is no exception. To attract more foreign tourists, Taiwan proposed Doubling Tourist Arrivals Plan. Since direct charter flight between mainland China and Taiwan has begun in 2008 and more mainland China tourists are allowed to visit Taiwan, a large number of business opportunities are created. Therefore, how to increase tourist attractiveness to grasp those opportunities has become the main issue in Taiwan. The present study reviewed relevant literature and then adopted data analysis to evaluate the results of Doubling Tourist Arrivals Plan. In addition, SWOT analysis was used to explore strengths and weakness of Taiwan tourist industry and Taiwan's environment for tourism development. Based on the outcome of the previously conducted analyses and also on references of Korean's and Ireland's tourism marketing strategy, four strategies suitable for Taiwan tourism were suggested to tourism operators: target market strategy, positioning strategy, marketing mix strategy, and competitive strategy.
