供应链中存在单一生产商、单一零售商和一个交易流动性不对等的第三方B2 B电子交易市场。在零售需求不确定的情况下，分别建立了供应链集中决策模型、传统固定合约均衡决策模型、收入共享契约分散决策模型，验证了收入共享契约在多渠道采购环境下仍可以协调供应链，分析了使供应链达到帕累托改进的收入共享契约的参数设定，最后分别从卖出流动性和买入流动性两个角度讨论了交易流动性对供应链的影响。研究结果表明，卖出流动性好的电子交易市场可以促使供应链达到最优生产量，实现整体收益的最大化；两种交易流动性的趋好都会提高供应链效率，但生产商更偏好卖出流动性好的电子交易市场。%Considering a supply chain consisting of a manufacturer , retailer and third-party B2 B online spot mar-ket , we derive the optimal system output from a centralized model of supply chain , and research the optimal fixed price and the optimal order quantity in a Stackelberg game model with wholesale price contract .Then we take a cooperative game approach in this paper to consider the coordination issue using revenue sharing contracts .We build a decentralized model with revenue sharing contract , and prove that the revenue sharing contract can coor-dinate supply chain .Using the wholesale price mechanism as a benchmark , we study the effect of Pareto-improvement with revenue sharing contract .Finally, we discuss the impacts of spot liquidity on supply chain coordination .Our study demonstrates that a B 2 B online spot market with good spot liquidity of selling can pro-mote supply chain to achieve coordination with optimal production .Although efficiency of supply chain can be improved by increasing spot liquidity , the manufacturer prefers good spot liquidity of selling to that of buying .
