We are now living in a society in which our life space enlarges rapidly by the improvement on transferability of persons, goods, and information. We call such society "highly integrated interacting society", in which we are demanded to harmonize both logic of life and regional development. We define the interaction theory as a theory that can meet the demand above. The theory aims to describe and explain the problems of confrontation between use and management of regional resources. And for that it must have some requisite as below; (1) To treat life activities as the process of solving life problems, (2) To introduce the concept of the transferability above into the process, (3) To specify an area for regional development and set the structure of supply and demand of the resources there, and (4) To put the mechanism of resource supply based on the cooperation formed by residents and visitors in the area.
