摘　　要：针对中小型初创企业因自身信用风险较低等造成的融资困难问题,建立一个由资金短缺且风险规避型零售商和风险中性供应商组成的二级供应链。零售商采用贸易信贷(延迟支付)策略进行融资,并与强势供应商进行Stackelberg博弈,利用CVaR风险度量准则进行决策,并引入回购契约对供应链进行协调,寻找供应链的帕累托最优区域。研究表明:贸易信贷利率固定时,风险度量因子与订购量呈正相关关系;利率可变且当零售商对于风险规避的程度保持在一个警惕但又不完全放松的状态时,供应商可以通过调整利率促使零售商达到最大订购量;供应链上各企业应当实施回购契约来加强合作,增大自身的利润,通过调整回购参数可获得帕累托最优区域。In response to the problem of financing difficulties due to the low credit risk for small and medium-sized start-ups,a two-echelon supply chain composed of risk-averse retailers and risk-neutral suppliers is established.Retailers use a trade credit(delayed payment)strategy for financing,and the Stackelberg game with strong suppliers,using CVaR risk measurement criteria for decision-making and introducing buyback contracts to coordinate the supply chain to find the Pareto optimal area of the supply chain.The research shows that when the interest rate of trade credit is fixed,the risk measurement factor has a positive effect on the order quantity;when the interest rate is variable and the retailer stays in a vigilant but not completely relaxed state of risk aversion,the supplier can adjust the interest rate to encourage the retailer to reach the maximum order quantity.Enterprises in the supply chain should implement repurchase contracts to strengthen cooperation and increase their profits,and obtain Pareto optimal region by adjusting the key parameters.
