Research On Supply Chain Cost Control Of E-commerce Enterprises Under The Background Of Block-chain

With the development of modern information technology and the rapid rise and development of the network technology field,E-commerce giants such as JD.com and Alibaba have emerged as the times require,subverting people's consumption habits.The economic benefits of e-commerce companies have gradually become an important driving force for Chinese economic and social development.More and more companies are aware of the dividends of e-commerce,and the intensified competition has led companies to seek new ways to increase their own interests.Due to the unique operating methods of e-commerce companies,it is difficult for them to profit from the prices and costs of the products.Supply chain cost management is directly related to corporate profits,and is called the third source of corporate profits.The goal of cost control can be achieved through comprehensive analysis and control of the supply chain.The continuous development of block-chain applications and applications based on technical scenarios have attracted widespread attention in various fields.The security and immutability of the block-chain get rid of the trust problem of traditional e-commerce companies.,and build a block-chain-based digital procurement system,freight logistics management system,payment management system and credit system and other core management systems,which can reduce such things as Network technology information content is insecure and complicated transaction costs and other problems,and create a reliable e-commerce Internet ecological environment.As a leading company in the B2 C field in my country,JD.com has gradually and rationally deployed block-chain applications since 2016 and applied them to all stages of supply chain cost management.Therefore,this paper takes JD.com as an example,which has certain symbolic significance and certain scientific research value.This paper takes JD.com as an example,based on the application of block-chain technology,supply chain management and other related basic theories,using literature research methods,case study methods and comparative analysis methods to study the current situation of cost control in the internal and external supply chain of JD.com..In the example part,the paper first analyzes the current status of JD's supply chain cost management based on block-chain applications.JD.com establishes alliance chains with distributors in external supply chain,thereby reducing the "bullwhip effect of supply chain management".And use the traceability and security of the block-chain to establish a "trust mechanism" with customers.In the internal supply chain,the use of block-chain technology to realize the digitization of the procurement link,refine the granularity of precision marketing in the sales link,synchronize information sharing to realize inventory rationalization,and use technologies such as "signing on the chain" and "Jingyuan chain" to realize the logistics link transparency and traceability,it is not difficult to see that block-chain technology has achieved certain results in supply chain cost control.Secondly,analyze the data of the purchasing costs,operating costs and logistics costs of JD.com from 2014 to 2019,and compare with the foreign leading self-operated e-commerce company Amazon.At the same time,analysis the effects and problems of cost control in the supply chain.Finally,it clearly puts forward the shortcomings and suggestions of JD's supply chain cost control based on block-chain technology,which provides a reference for JD.com to further apply block-chain applications to improve supply chain cost management.Through combing domestic and foreign literature,it is found that how to better manage supply chain management has become a key issue for e-commerce companies.This core cost control concept has long lagged behind digital technology,and the application of block-chain has opened up a new development path for the traditional supply chain.Compared with foreign countries,China's theoretical research on block-chain is relatively late,and there are fewer scientific studies on integration cases.Taking JD.com as an example,the application rate of its block-chain application has exceeded the speed of theoretical basic research.Most scientific research in China only stays in the application of supply chain management combined with block-chain,and the scientific research on cost control is still very important.Few,has certain research significance.Therefore,through the research of this article,the theoretical knowledge of block-chain in supply chain cost control can be enriched,and based on the actual effect of JD's supply chain management cost control under block-chain technology,it is clearly proposed that JD.com is under block-chain technology.The problems and suggestions on cost control of supply chain management in China provide a reference for JD.com to further use block-chain technology to improve supply chain cost control.At the same time,it also helps other companies or industries understand the practical value of block-chain technology for supply chain cost control,and expand the application of block-chain technology in different industries.
