Abstract
Interaction between regions is commonly focused on regional policies from the viewpoint of local revitalization. An interaction whose main purpose is sightseeing is analyzed in this study. An interaction index is proposed which can evaluate influence on the region of destination quantitatively in consideration of economic consumption. Economic consumption varies along with the sojourn time at the region of destination. An interaction model is formulated by constructing a consumer behavior model which is based on the Utility Maximization Theory. In order to develop a method to measure the degree of influence due to interaction, parameters of this model are estimated. As a result, it is clarified that interaction is influenced by travel cost, attraction of destination region and relationship between regions. In addition, degree of influence on prefectures in Japan by interaction is calculated and revitalization is discussed.
