According to the past experiences, all marketing theories are mainly focusing on the operation of enterprises, not much people consider marketing as one of a nation's occupational functions. Along with the uprising trend of mix economy these days, governments are now having their power interfering the information asymmetry and external benefit of tourism business. The role of a nation has changed especially on how to deal with the severely competitive tourism market global-wide. Instead of being passive administrators, governments have altered themselves into the role of ”posturers” who lead the business to explore and expand. Other than using the strategic planning models to stimulate the innovation of the industry and to upgrade, constructing some beneficial platforms for enterprise investments is also a considerable movement. On top of that, governments also know how to seize the moment to upgrade the industry to a leading successful level. By enthusiastically earning the sponsorship for the 2002 APEC, 2008 Olympic Games and 2010 world Exop, Mainland China has showed the real practice of using the idea of the marketing of a nation for improving its competitive advantages of tourism industry. This provides an illustration for Taiwan, who has also been actively invigorating its tourism industry.
