数据共享是供应链企业充分发挥数据要素价值的必要条件，区块链技术的发展有助于提升供应链数据共享水平。本文分析了区块链技术对供应链数据共享的驱动作用，并建立了供应链多主体数据共享演化博弈模型，通过仿真模拟的方法探索了供应链数据共享的影响因素及其演化路径。研究结果表明：第一，区块链技术的应用有利于供应链内确认数据权属、统一数据标准、降低数据风险、提高惩罚力度，进而提高供应链数据共享水平；第二，数据共享激励系数和惩罚系数对供应链多主体数据共享意愿有正向影响，数字系统建设成本、共享边际成本和数据风险系数对其有负向影响。

Data sharing is a prerequisite for supply chain enterprises to make full use of data elements. Meanwhile, the development of blockchain technology is conducive to improving the level of supply chain data sharing. This paper analyzes the driving effect of blockchain technology on supply chain data sharing, and then establishes the evolution game model of supply chain multi-agent data sharing. By means of simulation, this paper explores the influencing factors and evolution path of supply chain data sharing. The research results show that: First, blockchain technology is conducive to data ownership confirmation, data standardization, data risks reduction and the enhancement of punishment, which promotes the data sharing in turn. Secondly, the incentive coefficient and penalty coefficient of data sharing have a positive influence on the willingness of multi-agent data sharing in supply chain, while the construction cost, sharing marginal cost and data risk coefficient of digital system have a negative influence on it.
