摘要 考虑以一个电商平台和一个第三方物流服务商构成的两级电商供应链为研究对象,针对第三方物流服务商完全掌控自身物流服务水平而引发的道德风险问题,分析采用区块链技术对防范第三方物流服务商道德风险的策略。通过借助以区块链技术为基础的物流服务水平监控系统,考虑采用区块链技术和不采用区块链技术两种情景,分别建立分散决策下电商平台与第三方物流服务商之间的Stackelberg博弈模型,研究区块链技术应用前后供应链利润的变化情况以及与技术成本投入的关联性,最后通过数值分析验证结论的正确性。结果表明:当区块链技术的成本投入控制在一定的范围内时,应用该技术可以有效降低第三方物流服务商存在的道德风险,提高整个供应链利润的同时促进供应链各节点企业收益的有效提升,助力供应链的健康有序发展。

英文摘要 Considering the two-level e-commerce supply chain composed of an e-commerce platform and a third-party logistics service provider as the research object, aiming at the moral hazard problem caused by the third-party logistics service provider's complete control of its own logistics service level, this paper analyzed the strategy of using blockchain to prevent the moral ha-zard of the third-party logistics service provider. With the help of the logistics service level monitoring framework based on blockchain, considering the two scenarios of adopting blockchain and not adopting blockchain, it established the Stackelberg game model between e-commerce platform and the third party logistics service provider under decentralized decision-making, and studied the changes of supply chain profits before and after the application of blockchain and the correlation with technology cost input. After that, it verified the correctness of the conclusion by numerical analysis. The results show that when the cost input of blockchain is controlled within a certain range, the application of this technology can effectively reduce the moral hazard of the third-party logistics service providers, improve the profits of the whole supply chain, promote the improvement of the profits of each node of the supply chain, and help the healthy and orderly development of the supply chain.
