Abstract:In accordance with the law, prosecutorial organs supervise investigative organs' exercise of investigative rights, which should not only fix the weakness in supervision resulting from the opposition from investigative organs and lack of inner motivation as well, but also improve the lack of efficacy in supervision because of unsmooth information communication. A thorough analysis with the game theory may better deal with the interaction between the supervisor and the supervisee. Bringing in the third party, that is, parties involved and other litigation participants in specific cases may realize the maximum benefits for both game players and maximize the efficacy of supervision.
