Random demand,random market price and market access degree was considered under e-market environment.  On the basis of Stackerlberg game，the stochasticexpectation model for supply chain option contract coordination is established.  As the leader，the supplier declares the optimal contract reservation costs and execution costs for maximizing his expected profit，while as the follower，the purchaser responds with the optimal orders for maximizing his expected profit. The given Stackerlberg model was solved by the hybrid intelligent algorithm，including Monte Carlo simulation，artificial neural network，and genetic algorithm.  Combined with the e-commerce practice of Shanghai Baosteel Yichang Corporation，the demonstration analysis was carried out，and the optimal order quantity，contract reservation costs and execution costs of supply chain option contract coordination were worked out by using hybrid intelligent algorithm.
