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B2B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。
In the supply chain there is a single producer, a single retailer, and a third-party B2B electronic trading market with unequally trading liquidity. Under the circumstance of uncertain retail demand, we establish the supply chain centralized decision model, the traditional fixed contract equilibrium decision model and the revenue sharing contract decentralized decision model, respectively. It verifies that the revenue sharing contract can still coordinate the supply chain under the multi-channel procurement environment. In order to achieve the Pareto improved revenue sharing contract, the supply chain is set up. Finally, the influence of transactional liquidity on the supply chain is discussed respectively from the perspective of selling liquidity and buying liquidity. The results show that selling liquidity electronic trading market can promote optimal production volume in the supply chain and maximize the overall profitability. The two types of trading liquidity tend to improve the supply chain efficiency, but the producers prefer to sell Liquid electronic trading market.
