摘　　要：随着我国建筑业转型升级,装配式建筑越来越受到重视。但装配式建筑供应链中的信息共享也随之出现了诸多问题,例如信息易篡改和采集困难等,区块链技术的出现为解决装配式建筑供应链的信息共享问题提供了新的解决途径。本文首先搭建了基于区块链技术的装配式建筑供应链信息管理系统框架,保证上链后的信息无法被篡改;其次为确保上链前的数据真实可靠,对参与方构建是否共享初始真实信息的演化博弈模型,分析影响博弈方共享信息的影响因素及其演化路径;最后使用MATLAB进行仿真,结果表明:当装配式建筑供应链上各企业的信息共享程度、协同收益、激励和惩罚系数的提高对装配式建筑供应链主体信息共享意愿有正向影响,而共享信息的成本和信息风险系数对其有负向影响。With the transformation and upgrading of China’s construction industry,prefabricated buildings are getting more and more attention.However,there are many problems in information sharing in the prefabricated building supply chain,such as easy tampering and difficult collection of information,etc.The emergence of blockchain technology provides a new solution to solve the information sharing problem in the supply chain of prefabricated buildings.At first,a framework of information management system of prefabricated building supply chain based on blockchain technology was firstly built to ensure the information can not to be tampered;then,in order to ensure the reliability of information shared by each participant in the platform,an evolutionary game model was constructed for participants on whether to share initial real information,and the influencing factors affecting the information shared by the game parties and their evolutionary paths were analyzed;finally,MATLAB was used for simulation.The results show that the degree of information sharing,synergistic benefit,incentive and penalty coefficients had a positive impact on the willingness of information sharing among the main players in the prefabricated building supply chain when the degree of information sharing,synergistic benefit,incentive and penalty coefficients are increased,while the cost of sharing information and the information risk coefficient had a negative impact.
