摘要：AbstractTourism is an important economic sector in many countries. Touristic mobility depends on the availability of touristic assets in different locations, as well as on the access to different activities (bathing, leisure, culture, etc.) at different places. The consumption of different activities, the frequency at which these are accessed, the (active) accessibility to activities of candidate locations for staying, the level and distribution in the region of touristic assets, all of these are variables of an analytical model able to represent in an aggregate way how the opportunities for staying are distributed across the candidate temporary accommodation in the region. The model is based on the random utility theory, in particular on the concept of inclusive value, used in order to compute appropriate accessibility indexes. The proposed model can be exploited by two different points of view. The main is the point of view of the suppliers of touristic services; these could allow the tourist to access a web-based platform to be queried for an aggregate map of the touristic accessibilities of different zones in a pre- selected large touristic region. The map can be different for different tourists with different needs, changing on the base of the desired activities as ranked in input by the tourist during the querying procedure. Another point of view is the one of the public authority responsible for the promotion of touristic activities and the support/planning of touristic facilities. The application of the model and the exploitation of the accessibility concept is presented in the paper with reference to a case of study, the Campania region in the south of Italy, characterised by a large variety of touristic assets and opportunities ranging from cultural heritage to bathing localities, from wine and food to naturalistic assets, et cetera.
