In my former works [Hojo: 2000[Hojo: , 2001a・b, 2002a・b, 2003]], I tried to develop the multiplier models of tourism (income).

In addition, on the same article, area innovation multiplier theory was developed tentatively. In this paper, I try to develop tourism income and area income multipliers that contain social cost. I hope that this article helps to develop in related fields in the multiplier theories.
