Abstract
Legitimacy is defined as people’s evaluated approvability of others’ or own rights to decide public policies according to some reasons or values. In the present research, legitimacies and determinants among various actors around the decision rights of policies for NIMBY problem were examined between high-relevant concerned parties and low-relevant third parties who are related to policies of American military bases in Okinawa prefecture. We focused on trustworthiness and legality as determinants of legitimacies. Effects of trustworthiness toward legitimacy are hypothesized to vary across each actor among concerned parties, because they are motivated to process information minutely. Among third parties, on the other hand, legitimacies of related actor are evaluated according to peripheral clues, so it was hypothesized that both trustworthiness and legality to be determinants uniformly. Although these hypotheses were supported, the third parties were suggested to arouse a strategic process approving legitimacies of particular actors to maintain their own benefits as a result of acquirement of information about NIMBY structure. This paper discussed on theoretical perspectives to investigate consensus among various actors over public policies from the frame of rights structure.
