Purpose

Vaccine safety is a major issue in the world. Blockchain technology is the right solution to this worldwide problem. The impact of introducing blockchain technology on the operational efficiency of the vaccine supply chain is unclear. Therefore, from the perspective of game theory, this paper aims to construct a vaccine supply chain model consisting of a vaccine manufacturer, a vaccine traceability service platform based on blockchain technology and a vaccination unit to discuss its pricing and coordination.

Design/methodology/approach

This study analyzes the pricing and coordination of the vaccine supply chain based on blockchain technology, compares the decision-making of fixed charge scenario and proportional charge scenario and reveals the impact of blockchain on the vaccine supply chain.

Findings

Results demonstrate that the revenue-sharing contract can coordinate the vaccine supply chain when the proportion of revenue sharing meets certain conditions. The fixed charge scenario is more beneficial to the vaccine supply chain than the proportional charge scenario. The introduction of blockchain technology increases the total profit, consumer surplus and social welfare of the vaccine supply chain. Therefore, the operational efficiency of the vaccine supply chain is improved.

Originality/value

This study not only provides important support for enterprises to adopt blockchain technology but also provides some guidance for decision-makers to implement scientific and feasible vaccine supply chain management schemes.

基于区块链技术的疫苗供应链定价与协调

目的

疫苗安全是世界上的一个重大问题。区块链技术是解决这一全球性问题的正确方法。引入区块链技术对疫苗供应链运营效率的影响尚不清楚。因此，本文旨在从博弈论的角度构建由疫苗生产商、基于区块链技术的疫苗溯源服务平台和疫苗接种单位组成的疫苗供应链模型，讨论其定价和协调。

设计/方法/方法

本研究基于区块链技术分析疫苗供应链的定价和协调，比较固定收费场景和比例收费场景的决策，揭示区块链对疫苗供应链的影响。

发现

结果表明，当收益分享比例满足一定条件时，收益分享合同可以协调疫苗供应链。固定收费方案比按比例收费方案对疫苗供应链更有利。区块链技术的引入增加了疫苗供应链的总利润、消费者剩余和社会福利。因此，提高了疫苗供应链的运行效率。

原创性/价值

本研究不仅为企业采用区块链技术提供了重要支持，也为决策者实施科学可行的疫苗供应链管理方案提供了一定的指导。
