Research On Financing Interest Rates And Logistics Cost Decisions Of Third-party Logistics Enterprises In Cross-border E-commerce Environment

Cross-border e-commerce has shown strong development vitality,cross-border ecommerce enterprises to open overseas warehouse business can overcome the traditional crossborder logistics exist in low timeliness,high cost and can not return goods and other problems,but overseas warehouse storage will take up a lot of liquidity,cross-border e-commerce enterprises themselves light assets,low credit rating,lack of security and other high-risk factors,it is difficult to obtain loans from banks,there is a financing dilemma,in urgent need of Financial institutions need to provide financial support to ease the pressure.The rise of the supply chain sector has provided new research ideas to solve the financing difficulties of crossborder e-commerce enterprises.By coordinating logistics,capital flow and information flow,third-party logistics enterprises take advantage of the supervision of goods in the supply chain to reduce financing risks and play a leading role in supply chain finance,and can carry out integrated international logistics and trade credit financing services for cross-border ecommerce enterprises with capital needs,so in the cross-border Under the environment of crossborder e-commerce,it is of great significance to carry out research on the financing interest rate decision and logistics cost decision of third-party logistics enterprises and the decision on the order quantity of goods in the overseas warehouse of cross-border e-commerce enterprises.In this thesis,by constructing a secondary supply chain consisting of third-party logistics enterprises and cross-border e-commerce enterprises,and considering factors such as uncertainty of overseas demand,random fluctuations of exchange rates and tariff barriers to trade,the Stackelberg game model is established for the case of the newsvendor model and the financing model of third-party logistics enterprises,and the optimal financing interest rate and logistics cost of third-party logistics enterprises are solved by using the mathematical backpropagation method decision function and the optimal order quantity decision function of cross-border e-commerce enterprises,as well as the functional relationship between the exchange rate and tariff on the impact of the decision of the constituent parties,the main research results and conclusions are as follows:(1)The optimal order quantity decision of cross-border e-commerce enterprises is negatively correlated with cost factors such as tariff rate and wholesale price per unit of product,and positively correlated with exchange rate,and there is a one-to-one functional relationship between them.(2)In the financing model of international logistics enterprises,the optimal order quantity decision of cross-border e-commerce enterprises is negatively correlated with the logistics cost per unit of product and the financing interest rate,and the logistics cost per unit of product and the financing interest rate have the same moderating effect on the decision of cross-border ecommerce enterprises.(3)In the financing model of international logistics enterprises,the optimal unit product logistics cost decision of international logistics enterprises is a concave function of the exchange rate.The smaller the exchange rate difference between import and export countries,the more the unit product logistics cost gradually increases;the higher the tariff rate,the larger the exchange rate corresponding to the peak of the optimal unit product logistics cost,and the peak gradually increases.(4)In the financing model of international logistics enterprises,the optimal financing interest rate decision of international logistics enterprises is in three different situations,when the logistics cost per unit of product is high,the elasticity of the financing interest rate to the optimal order quantity is stronger,the increase of the financing business income cannot compensate for the decrease of the logistics business profit,and the maximum profit can be achieved by waiving the interest rate;when the logistics cost per unit of product is low,the elasticity of the financing interest rate to the optimal order quantity is weaker,and the interest rate can be set to the optimal order quantity.When the logistics cost per unit of product is low,the elasticity of the financing rate on the optimal order quantity is weak,and the highest financing rate can be set;when the logistics cost per unit of product is medium,there is an optimal threshold for the elasticity of the interest rate on the optimal order quantity regulation,and the regulation function is maximised.The results of the study can provide scientific references for the logistics operation decisions and trade credit financing decisions of international logistics enterprises and the procurement decisions of cross-border e-commerce enterprises.
