Abstract
In this paper, the conflict between players in infrastructure planning is interpreted as non-cooperative game, and opinion summarizing between players and their supporters is analyzed theoretically. First, the process that the conflict achieves an outcome is modeled as stationary game. Second, the condition that should be satisfied by opinion summarizing mechanism is clarified. Third, two opinion summarizing mechanisms, state-based and action-based mechanisms, are formulated. Finally, the formulated mechanisms are applied to the conflicts between government and residents group, and the conflicts are classified based on sensitivity against the difference of opinion summarizing mechanisms.
