Game Analysis on Construction Quality Risk Supervision Based on Collusion Behavior

摘要

By setting up the game model of utility function, this paper conducts game analysis based on the collusion behavior at the expense of damaging construction quality between supervisors and supervisees in the field of construction quality risk management Backward induction was adopted to obtain the equilibrium solution; analysis on the solution demonstrates that the supervision potency dimension of supervisors has a direct influence on the construction quality. Adopting constrain and incentive measures is beneficial to improve the supervision potency dimension and prevent collusion behavior from happening; moderate supervision, the combination of supervision and incentive, is advantageous to the enhancement of supervisees' working initiatives, reduction of collusion and guarantee construction quality.
