考量市场需求不确定下绿色供应链融资策略及选择——兼析供应链最优生产决策与供应商最优融资方式

Financing Strategy and Choice of Green Supply Chain Considering Market Demand Uncertainty——Analysis on the Optimal Production Decision of Supply Chain and the Optimal Financing Mode of Suppliers

绿色供应链是促进环境和经济协调发展的有效手段。在绿色供应链市场总需求不确定的情况下,为解决供应商在提高产品绿色度时出现资金约束的问题,建立以供应商为主导的Stackelberg博弈模型,分析提前支付与银行贷款两种融资模式下,供应链的最优生产决策与供应商的最优融资方式。研究表明:两种融资模式下的最优决策与初始资金无关,只与提前支付折扣/银行贷款利率有关;当提前支付折扣与银行利率相等时,供应商总是会优先选择提前支付融资模式解决约束问题。然后,应用数值模拟分析进一步验证了上述结论。据此,提出提高对绿色理念的关注度、大力发展绿色金融、推动绿色领域的技术和模式创新等建议。

Green supply chain is an effective means to promote the coordinated development of environment and economy. Under the uncertainty of the total market demand of green supply chain, in order to solve the problem of capital constraints when suppliers improve the green degree of products, a Stackelberg game model led by suppliers is established to analyze the optimal production decision of supply chain and the optimal financing mode of suppliers under the two financing modes of prepayment and bank loan. The results show that the optimal decision-making under the two financing modes has nothing to do with the initial capital, only with the advance payment discount/bank loan interest rate;When the prepayment discount is equal to the bank interest rate, the supplier will always give priority to the prepayment financing mode to solve the constraint problem. Then, the above conclusions are further verified by numerical simulation. Finally, in order to promote the rapid development of green supply chain, some suggestions are put forward, such as improving the attention to green concept,vigorously developing green finance, and promoting the technology and mode innovation in the green field.
