基于区块链的建筑供应链信息共享演化博弈研究

Research on Evolutionary Game of Building Supply Chain Information Sharing Based on Block Chain

摘要:

建筑供应链内的信息共享是提高项目管理绩效的有效途径，但信息的不对称、不安全和追溯困难严重制约了建筑供应链内各参建方的信息共享效率。为加快建筑行业的转型升级，本文引入区块链技术，提出建筑供应链信息共享的新组织模式，并用JAVA语言进行实现；同时，结合演化博弈理论，构建基于核心方-从属方的演化博弈模型，从利益实现的角度出发，探索新组织形式下建筑供应链信息共享的影响因素。结果表明，建筑供应链各参建方之间的信息共享水平、信息转移系数、财政补贴等因素对信息共享新组织模式的形成有正向作用；信息共享成本和风险系数对新组织模式的形成有不利影响。

Abstract:

Information sharing in the construction supply chain is an effective way to improve the performance of project management, but the information asymmetry, insecurity and traceability difficulties seriously restrict the efficiency of information sharing among the participants in the construction supply chain. In order to speed up the transformation and upgrading of the construction industry, this paper introduces the blockchain technology, puts forward a new organizational model of information sharing in the construction supply chain, and combines the evolutionary game theory to construct an evolutionary game model based on the core-subordinate side, and explores the influencing factors of information sharing in the construction supply chain under the new organizational form from the perspective of benefit realization. The results show that the level of information sharing and the coefficient of information transfer among the participants in the construction supply chain Financial subsidies and other factors have a positive effect on the formation of the new organizational model of information sharing; the cost of information sharing and the risk coefficient have a negative impact on the formation of the new organizational model.
