区块链环境下供应链网络演化研究

Research on the Evolution of Supply Chain Networks in the Blockchain Environment

随着世界经济的快速发展,部分发达国家借助其掌握的区块链核心技术对其国内大型企业的供应链管理做出了一系列优化。为了实现区块链在中国企业供应链技术领域的广泛应用,中国明确提出了关于区块链应用和供应链技术发展的指导意见。在指导意见的引领下,中国区块链环境下的供应链网络建设持续发展,且呈现出了不断优化的良好局面。本文将区块链技术结合到供应链网络中,探究区块链环境下供应链网络形成网络演化的规律。在传统供应链网络模型的基础上,引入区块链技术的PBFT共识机制,并进行优化,得到基于信用评价的共识机制CDBFT,同时通过Agent理论将供应链网络的企业节点进行等效分析;将区块链技术映射到供应链网络的企业行为中,以智能合约的形式将影响供应链网络的因素加入到网络演化中,改变了传统供应链网络的连接方式。在优化后的共识机制和多Agent供应链网络企业交互的智能合约的基础上构建新型供应链网络演化模型,并对其网络演化进行复杂网络相关特性分析。实证研究表明:即使是在去中心化的区块链供应链环境下,供应链网络也会呈现出节点幂律分布的特点和无标度特性,但在该环境下使得供应链网络中的企业具有匿名可信、交易记录透明可追溯的特点,由此解决了信任机制的相关问题,使得交易双方是完全可信的,为今后的信息服务带来新变革,既能进行身份认证,也可以与人工智能相结合,为企业提供信息服务,帮助管理大数据的生命周期,在提高供应链效率管理中发挥重要作用。

With the continuous development of the world economy,developed countries have made a series of optimizations on the supply chain management of large enterprises with the help of the core blockchain technology.At present,Chinese enterprises are in a global economic integration environment.In order to realize the wide application of blockchain in the field of Chinese enterprise supply chain technology,China clearly put forward guidance on the application of blockchain and the development of supply chain technology.Under the guidance of the guiding opinions,the supply chain network construction in China’s blockchain environment continues to develop,and has shown a good situation of continuous evolution.Combine the blockchain technology into the supply chain network,and explore the law of the network evolution of the supply chain network in the blockchain environment.On the basis of the traditional supply chain network model,the PBFT consensus mechanism of blockchain technology is introduced,and the consensus algorithm is optimized to obtain the consensus mechanism CDBFT based on credit evaluation.At the same time,the enterprise nodes of the supply chain network are equivalent through the Agent theory analysis;And map the blockchain technology to the corporate behavior of the supply chain network,and add the factors that affect the supply chain network to the network evolution in the form of smart contracts,changing the connection mode of the traditional supply chain network.Construct a new supply chain network evolution model based on the optimized consensus mechanism and the smart contract of multi-agent supply chain network enterprise interaction,and analyze the complex network characteristics of its network evolution.Empirical research shows that even in a decentralized blockchain supply chain environment,the supply chain network will show the characteristics of power-law distribution of nodes and the characteristics of scale-free,but in this environment,enterprises in the supply chain network have the characteristics of anonymity and trustworthiness,and the transaction records are transparent and traceable,which solves the problems related to the trust mechanism,makes both parties of the transaction completely credible,and brings new changes to future information services.It can be used for both identity authentication and combining with artificial intelligence,providing information services for enterprises,helping to manage the life cycle of data,is indispensable for efficient management of the supply chain.
