Abstract: Taking the representative case of Yunnan in Southwest Frontier Mountain areas, this paper establish the transportation advantage degree evaluation index system from the aspects of the density of the highway networks, influence degree of traffic facilities, and traffic accessibility to evaluate and compare all around state of Yunnan province in 2011. And then on the base of Yunnan tourism economic comprehensive development level by entropy evaluation method, this paper build the model of tourism industry and regional transportation development coupling coordination degree in physics, to research the Coupling and the coordinated development degree of transportation advantage degree and tourism economy development level, and divide the Coupling – coordination type area. The empirical research shows : Southwest frontier mountain area have a great difference in transportation advantage degree, presenting the circle layered spatial pattern that take the area and adjacent counties or cities as the core decreasing gradually from the core to peripheral cities. The development of tourism economy has an obvious polarization trend, and the development of the tourism industry is restricted by the traffic location and terrain conditions. Spatial coupling coordination between Regional transport superiority and the development level of tourism industry is not significant and the development of regional tourism is lack of transportation supports.
