| 摘 要： | 消费者不信任严重制约延保服务行业的发展，投资区块链技术可以提升消费者的信任度并为企业带来信任效用，同时也会增加巨额的区块链应用成本。本文分析该技术投入前后供应链均衡解的变化，探寻技术和经济价值目标条件下延保服务供应链实施区块链的充分条件，最后对结果进行算例分析。研究表明：在未实施区块链的情形下，延保服务削弱因子将负向影响供应链均衡解。当实施区块链的固定成本大于一定限度时，制造商实施区块链后的利润小于实施区块链前的利润。当考虑信任效用时，供应链成员实施区块链的条件相比未考虑效用时更为宽松，且零售商实施区块链的条件最为宽松。存在一个最优的消费者信任度差，使制造商在技术价值目标下投资区块链技术的充分条件最宽松。 |

| Abstract: | Consumer distrust seriously restricts the development of the extended warranty service industry, and investing in blockchain technology can enhance consumer trust and bring trust utility to enterprises, while also increasing the huge cost of blockchain applications. This paper analyzes the changes in the equilibrium solution of the supply chain before and after the technology investment, explore the sufficient conditions for the implementation of blockchain in the extended warranty service supply chain under the condition of technical and economic value objectives, and finally analyze the results. Studies have shown that in the absence of blockchain implementation, the weakening factor of extended warranty services will negatively affect the equilibrium solution of the supply chain. When the fixed cost of implementing a blockchain is greater than a certain limit, the manufacturer's profit after implementing the blockchain is less than the profit before the implementation of the blockchain. When considering trust utility, supply chain members are more relaxed in implementing blockchain than when utility is not considered, and retailers are the most relaxed in implementing blockchain. There is an optimal poor level of consumer trust, making the fullest conditions for manufacturers to invest in blockchain technology under the goal of technical value. |
