According to the perfect Nash equilibrium result,this paper suggests that under constant market conditions the optimal reservation price of sellers is decided by the seller s preference factor on days on the market and is negatively relative to it.

The subgame perfect Nash equilibrium which leads to profit maximization is given when there are different types of consumers.

Considering the fixed demand and different decision-making dominations of the buyer and supplier in the scarcity time, the paper studies the cooperation system of two level supply chain, establishes dynamic game model of incomplete information and gets out its perfect Bayesian Nash equilibrium.

The result of the imperfect and incomplete information dynamic game between investors and financing enterprises is perfect Bayesian Nash equilibrium,which damages the benefits of investors and financing enterprises.

Then,it studies the perfect Bayesian Nash Equilibrium of game.
