Abstract：Given that the option contract can be speculated after expiration in B2B e-marketplaces, we establish retailer’s profit models when credit is viable or not, and analyze the effect of the market liquidity on retailer’s optimal procurement strategy. The results show that the market liquidity of spot market always has effects on retailer’s procurement strategy in two scenarios. In the absence of credit financing scenario, when the market liquidity is high, the retailer will use more options as capital increase; in the credit financing scenario, with the increase of his own capital, bank loan interest rate is decrease, hence reduces long-term price contract procurement and raises option contract procurement. But retailer’s long-term contract quantity is higher and option contract quantity is lower than it can’t obtain loans.
