In the study on tourists, we found that they made choices prefer to on the ground of the integrated information of the destination where they would spend their holidays more willingly than on the ground of scattered information of it. Regional cooperation will conduce to tourism destinations' resources supplying each other, management assisting each other, sharing the target marketplace with each other, talent intercourse, and the integrated consideration of single tourism investigation, the goal of that is to enhance our competed capability of the world and make it duration. The region what we said breaks away from the limitation of traditional geographic region such as district, which is a more comprehensive concept about tourism. At present, large-scale united market and building up the tourism-integrated image have come to be a tendency in the world tourism marketplace that could not be reversed. Many world-famous tourism destinations' integrated image are becoming more and more shining, and the frequency of united market activity between countries in the region are becoming higher, such as Europe, Caribbean region, and southeast Asia. On the other hand, because of the similar cultural background, the divergent characteristics of natural and cultural resources, and the feasibility of regional cooperation, at the beginning of the regional cooperation network construction, that would be so better to choose traditional competitors (tourism destination) as elements to construct the network that could not only do more benefits but also avoid disordered competition as the result of repetitive development.
That is, with the transformation of views and target, regional tourism planning is gaining access into a new space that is more amplified and wider. Spatial competition and regional cooperation exist not separately, but relatively. In practice, we should confirm the extent of the collaborative region with the direct of the study of spatial competition. The six ancient towns in southern Jiangsu, which developed in the similar natural circumstance and identical cultural background, have similar spatial perception and target marketplaces, and the only way to solve the problem is regional tourism cooperation. This paper makes use of the GIS spatial analysis method to analyze the spatial structure of the regional cooperation network, that is an applicable method and could be used more in the tourism planning problems.
