Dynamic Relationship Research Of Stakeholders In Construction Industrialization Project

The construction industrialization project involves multiple stakeholders such as construction unit,design unit,construction contractor,component production unit,etc.Stakeholders have different interests,positions and risks in the project construction.It leads to low efficiency of stakeholder cooperation and strong antagonistic relationship.So it's necessary to study the relationship of stakeholders,analyze the mechanism of stakeholder relationship on project performance and innovation management mode,which can improve the cooperative relationship among stakeholders,the construction efficiency and the performance of construction industrialization projects and promote the development of construction industrialization.Based on stakeholder management,project performance and social network analysis,this paper analyzes the role of core stakeholders in the construction industrialization project and the relationship of stakeholders from relationship strength and network characteristic structure.Then this paper analyzes the measurement dimension of collaborative performance of construction industrialization projects,and builds the model of the influence of stakeholder relationship on collaborative performance through literature theoretical research.Finally,measures and reveal the effect of stakeholder relationship on project collaborative performance through the structural equation model.The results show that the communication,promise and cooperation of the stakeholders in the construction industrialization project have a positive effect on project performance.Among them,communication and cooperation have great effect on collaborative performance,and the influencing path coefficient is basically greater than 0.5.The effect of commitment on collaborative performance is small,and the path coefficient is generally less than 0.2.The trust has a positive effect on the performance of goals,processes,and stakeholder satisfaction,with the path coefficient between 0.45 and 0.65.Next,Combined with the characteristics and current situation of stakeholder management in construction industrialization projects,this paper proposes a new perspective of stakeholder dynamic relationship based on the change of management mode.Then through stochastic coefficient model to simulate the strength matrix of stakeholder relationship and construct the stakeholder relationship network structure of different project management modes.Finally,paper analyzes the dynamic changes of stakeholder relationship intensity,network structure characteristics and project collaborative performance under different project management modes.And conduct the influence model of stakeholder dynamic relationship on collaborative performance.Finally,combine the actual construction industrialization project,paper measures stakeholder relationship strength,network structure characteristics and project collaborative performance of DBB,DB and EPC models,and analyzes the collaborative performance of different stakeholder management modes based on the average relationship strength and relationship network structure characteristics of stakeholders.In EPC,the average relationship strength,network centralization of the stakeholders and overall collaborative performance are greater than other modes.However,with the lower network density and larger average path length,other stakeholders of EPC have fewer relationships,less information sharing,which leads to lower innovation and learning performance than other modes.Thus,the EPC model with impeccable information sharing mechanism should be promoted in the construction industrialization project to improve the innovation and learning performance.
