The deci­ sion models under revenue sharing contract or unprovided revenue sharing contract, risk neutral or risk averse of retailer are developed, respectively. The retailers optimal order quantity and negotiation interval of revenue sharing contract are recommended respectively. In conclusion, on the one hand, the optimal order quantity of revenue sharing contract is greater than unprovided revenue sharing contract. On the other hand, whether a revenue sharing contract is provided or not, the order quantity based on profit maximization is greater than that based on RPC maximization. Finally, it shows the relationship between the optimal order quantity of the
