The Power Asymmetry Affect Mechanism In Project Disputes And Metrics Model

Power asymmetry often exists among parties in construction disputes, which has its inevitability and rationality, and may change the evolution and outcomes of the disputes. If the power asymmetry is ignored in the process of analyzing the disputes, the outcomes often can not be accepted by the parties. Therefore, according the Cognitive Theory and Conflict Analysis, the impact mechanism of power asymmetry in disputes was analyzed in the paper. Furthermore, a measurement model of power asymmetry was structured based on the dynamic game theory.First, the paper discussed the connotation and cognition of power in the disputes, as well as the impact of power asymmetry on the cognition. On this basis, through analyzing the impact of power asymmetry on the elements of a conflict, such as players' options, feasible scenarios, and preference vectors, the impact mechanism on the outcomes of disputes was explored.Secondly, based on the characteristics of disputes with power asymmetry, the paper classified the players and options. Then, the measurement model of power asymmetry in disputes was structured, through applying the concept of prior probability and Bayes rule in dynamic game theory.Third, the characteristics and differences of the players'power in the disputes of demolition and wage arrears were analyzed, from the view of the possession of production, social resources, law, cognition, personality and so on. On this basis, the paper discussed the players'option types, ways of expression and selection in construction disputes under the condition of power asymmetry.Finally, a case study about construction disputes was conducted, which verifies the validity of the paper's results.
