摘　　要：电子商务的快速发展不仅带来更多的销售机会,而且也可以为中小企业提供融资服务,解决其资金短缺问题。为此,本文构建了由零售商、供应商和平台企业组成的电商供应链,且零售商与平台企业间存在价格竞争的决策模型,考虑零售商和供应商的风险规避性,探讨电商平台为资金约束的零售商或资金约束的供应商提供融资时,供应链各成员企业的最优决策及其效用。研究发现:①零售商和供应商的风险规避特性都将显著影响各企业的最优决策,而零售商和供应商的风险规避系数与各最优决策的相关性依赖于零售商或供应商是否存在资金约束;②供应商的风险规避特性可能会导致自身效用和平台企业利润的降低,促使零售商效用的增加;③零售商的风险规避特性将造成自身效用的损失和供应商效用的增加,同时使平台企业利润增加或减小。The rapid development of e-commerce not only brings more sales opportunities for small and medium retailers,but also provides financing services for them to solve their capital shortage issue.Such small and medium retailers are usually difficult to obtain adequate capital in reality and lack of anti-risk capabilities,which make them often adopt conservative strategies when making production and sales decisions,showing the characteristics of risk aversion.Since 2014,JD.com’s financing service has served 300,000 small and medium companies and 700,000 individual merchants,with a historical cumulative loan amount of nearly 600 billion.As an online sales channel for third-party retailers,e-commerce platforms charge certain usage fee according to retailers’sales revenue,and also obtain corresponding interest income by providing financing services for them.Retailers that have obtained financing service ensure the stability of the supply chain procurement and production business,and even expand sales,which further increases the platform's fee income,forming a mutually beneficial cooperative relationship between the two parties.On the other hand,it is commonly seen that platform companies now often establish their own retailing channels,adopt the resale model to sell products similar to those of third-party retailers,or even develop their own brand products to directly compete with other retailers.For example,“JD.com Jing Zao”,which was launched in January 2018,is a brand that JD.com cooperates with outsourcing manufacturers to sell on its platform.In this study,it is interesting in the sales and financing strategies of the platform and third-party sellers in the e-commerce supply chain environment where competition and cooperation coexist,and how the risk-averse characteristics of SMEs affect the optimal decision-making of supply chain members.To this end,an e-commerce co-petition supply chain composed of a risk-averse retailer,a risk-averse supplier and a risk-neutral platform is considered,and three scenarios a
