Considering that the classical Black-Scholes(B-S) option pricing model can not describe the characteristics of constant value periodicity and long-term dependence of financial asset prices, the time-changed mixed fractional Brownian motion is used to describe the changes of financial asset prices. By using self-financing delta hedging strategy, the partial differential equation of geometric average Asian call option price in discrete case and the pricing formula of geometric average Asian call and put option are obtained, and the influence of parameters in pricing model on option price is analyzed. Based on the daily closing price of Vanke stock, this article makes an empirical analysis on the established pricing model, and verifies the effectiveness of the pricing model.

Key words: Asian option, Time-changed process, Mixed fractional Brownian motion, Transaction cost
