Abstract: Based on the historical progress of utility theory and exchange theory, this paper constructed a wealth utility function of measuring player’s satisfaction for profit gained from the property bargaining based on the wealth preference of people. In the process of property bargaining, the changes of profits of seller and buyer as variables of wealth utility function well conduce to the wealth utility function in accordance with the law of dissatisfaction and the law of satisfaction decrease. In the basis of wealth utility function of individuals, the models of bargaining for property pricing were constructed and the equations of solving equilibrium price of bargaining were derived. On the state of equilibrium price, the effects of structure parameters changes of wealth utility function and the effects of model parameters changes of bargaining games on the property pricing were analyzed, which provides the scientific basis for the mechanism designs of property bargaining.
