B2B电子市场下商业信用筹资的供应链收入共享契约协调

考虑商业信用筹资对供应商与零售商各自目标利润及供应链的总利润的影响，从传统市场出发，分析了商业信用筹资时收入共享契约在实现供应链协调及收益合理分配方面的作用，建立了B2B电子市场下基于商业信用的收入共享契约协调模型，推导出实现供应链有效协调的最优契约参数.通过比较传统市场与电子市场的协调机制，结合信用期对最优契约参数的影响，得出商业信用筹资时供应链双方进入电子市场交易并实现收益合理分配的充分条件.最后通过数值算例说明了所得结论.

Supply Chain Coordination Based on Revenue Sharing Contract in B2B e Markets with Trade Credit Financing

Considering the effects of trade credit financing on supplier and retailer target profits respectively and total profits of supply chain， and starting from the traditional market， the effect of revenue sharing mechanism based on trade credit for supply chain coordination and distributing the profit was analyzed. The model of e market revenue sharing contract coordination based on trade credit was developed and the optimal contract parameters for rational allocation of income were derived. Considering the impact that credit period imposed on optimal parameters， by comparing the coordination mechanism in traditional market and e market， sufficient conditions were got for supply chain members to enter e markets and to realize the rational allocation of income. Finally， the conclusions were illustrated by a numerical example.
