As McKinnon (1964) argued, international tourism brings foreign exchange that can be used to import intermediate and capital goods to produce goods and services, which in turn leads to economic growth. Foreign tourism is Thailandûs largest export industry. Sales of tourism goods and services to international visitors averaged US$10.2 billion in 1998›2005 on more than 10 million annual visitor arrivals. During 1998›2005, on average, Thai tourism directly and indirectly accounted for 13 percent of Gross Domestic Product (GDP) and 10 percent of employment which is approximately 3 million jobs and 12 percent of investment. Using the industry ûs GDP share as a measurement, Thailand was ranked 60 out of 174 countries in the World Tourism and Travel Councilûs Tourism Satellite Accounts in 2005 (Wattanakuljarus and Coxhead,2008)
