THE STUDY ON SPATIAL LINKAGE BETWEEN THE SUPPLY AND DEMAND OF TOURISM

Tourist market involves the supply market and demand market. It is significant to maintain the balance of tourist supply and demand. This paper discusses the law of regional distribution and dynamic balance of tourist supply and demand. The author also defines the spatial models of tourist supply and demand.First, based on case studies, a new concept, tourist threshold population, is defined. The threshold population size of a tourist destination is the population size of tourists visiting the destination when input of tourism is equal to output.Secondly, a demand model is given. From the demand model, we can understand easily why the tourism in metropolitan areas often bring higher income than in remote regions.From the supply and demand models, tourist destinations can be divided into four types and conclusions on the space linkages of tourist supply and demand in the four types are drawn. The four types are listed as follows:1. tourist destinations are located in the core cities of metropolitan areas;2. torist destinations are located in the suburbs or outskirts of metropolitan areas;3. tourist destination are located beyond metropolitan areas;4. tourist destinations are located in remote regions.In the first situation, the supply and demand of tourism are overlapping in space, and the marginal profit of tourism is the largest. When the distance between a tourist destination and a core city increases, the marginal profit of tourism decreases.
