Abstract: This paper intends to search the change of bank’s profit when bank reduces even remitted commitment fee of acceptance bill from the standpoint of commitment rate. By establishing profit models of the retailer, the manufacturer and the bank, and successive analyses of retailer’s order quantity, manufacturer's choice of financing modes and bank's commitment fee rate, we find the following results: Commitment fee makes order quantity in confirming warehouse less than that in delaying payment, but the advantage that manufacturer can discount bank bill in advance can offset the disadvantage of order quantity. For bank, only commitment rate is reduced to be of critical value can confirming warehouse prior to delaying payment be manufacturer's choice of financing retailer. The optimal commitment rate is the result of both solving function of bank’s profit and considering competition between these two financing modes. Consequently, although banks reduce even remit commitment fee of acceptance bill for implementing the policy of “tax reductions and fee cuts”, they do not necessarily decrease their profit, and they can increase business of confirming warehouse. At the same time, reducing even remitting commitment fee of acceptance bill does good to improving supply chain efficiency.

Key words: confirming warehouse, commitment rate, order quantity, supply chain efficiency
