Research Abstract

This research aims to verify setoral and regional interdependency of Japanese industries under the influence of information security risks from the viewpoint of economy. The researcher proposes a methodology to quantitatively measure interdependency of information security among Japanese industries. The research applies this methodology in the recent Japanese economy and exhibits differences between information security interdependency and pure economic interdependency.
