Study On E-commerce Supply Chain Decision-making Different Dominant Models Under The Influence Of Blockchain

The traditional method of doing face-to-face transactions has been altered by the introduction of Internet e-commerce.E-commerce platforms have advanced quickly as a result of the new crown epidemic.Due to the growth and enlargement of e-commerce platforms,third-party logistics companies have also developed along the trend.The level of logistics services has steadily increased thanks to the quick expansion of Internet e-commerce platforms and the growth of third-party logistics service providers,thereby increasing the purchase of consumers who pursue service quality,thereby increasing market demand.However,due to poor supply chain management,insufficient data security and market transparency,e-commerce platforms have many problems of low circulation efficiency and poor security,which will decrease market demand,which will harm the interests of manufacturers,retailers,and third-party logistics service providers,and prevent them from maximizing their own interests.This will also increase mistrust between manufacturers,retailers,third-party logistics service providers,and customers.Therefore,it is urgent to introduce blockchain technology,use the characteristics of blockchain technology to improve the transparency of the transaction process,optimize payment methods,protect data security and privacy,etc.,so as to achieve the purpose of improving the supply chain management system.At the same time,the improvement of logistics service level and blockchain technology application level will also bring cost reduction effect.Yet,there is limited research on how the application of blockchain technology by various actors in various power structures,while taking into account its cost-saving advantages,affects supply chain decisions.Based on the above situation,this paper considers the relationship between logistics service level and blockchain application level investment and cost function,as well as the supply chain decision-making model affected by the different decision-making power structures of various entities in the decision-making process for the supply chain.By examining and contrasting how the three decision-making entities’ profit changes when manufacturers are under the control of various power structures,retailers and third-party logistics service providers apply blockchain technology.The results show that:(1)The direction of the action of parameters on the supply chain will not be affected by the change of power structure.(2)When manufacturers apply blockchain technology,the profit of manufacturers,retailers and logistics service providers,market demand,wholesale price,retail price,blockchain application level and logistics service level all change in the opposite direction with the blockchain application technology investment coefficient;and change in the positive direction with the blockchain cost coefficient and blockchain application sensitivity coefficient.(3)When retailers apply blockchain technology,the profit of manufacturers,retailers and logistics service providers,market demand,retail price,blockchain application level and logistics service level all move in the opposite direction to the blockchain application technology investment coefficient;and move in the positive direction to the blockchain cost coefficient and the blockchain application sensitivity coefficient.The wholesale price is not related to the blockchain application technology investment coefficient,blockchain cost coefficient and blockchain application sensitivity coefficient.(4)When logistics service providers apply blockchain technology,the profit of manufacturers,retailers and logistics service providers,market demand,wholesale price,retail price,blockchain application level and logistics service level all change in the opposite direction with the blockchain application technology investment coefficient;and change in the positive direction with the blockchain cost coefficient and blockchain application sensitivity coefficient.
