政府规制下装配式建筑供应链多元主体协作研究

Research on the Collaboration of Multiple Subjects in the Supply Chain of Assembled Buildings under Government Regulation

为提高装配式建筑供应链上下游企业合作意愿,基于政府规制视角构建设计单位、构件生产单位和施工单位演化博弈模型,分析三方策略的动态演化过程及稳定性条件,运用Matlab进行参数敏感性分析。结果表明:政府应加大支持力度,建立有利于行业发展的市场环境与竞争机制;参与主体协作意愿与政策支持、增量效益、初始成本降低系数呈正相关,与初始成本、增量成本呈负相关。研究结果对保证装配式建筑供应链的稳定性具有一定的实践意义。

To improve the cooperation willingness of upstream and downstream enterprises in the assembly building supply chain,we constructed an evolutionary game model of the design unit,component production unit,and construction unit based on the perspective of government regulation,analyzed the dynamic evolution process of the three-party strategy and the stability conditions,and carried out a parameter sensitivity analysis using Matlab.The results show that the government should increase support and establish a market environment and competition mechanism favorable to the development of the industry;the willingness to collaborate of the participating entities is positively correlated with policy support,incremental benefits,and the coefficient of reduction of the initial cost,and negatively correlated with the initial cost and incremental cost.The results of the study have certain practical significance in ensuring the stability of the assembly building supply chain.
