Research On Extension Of Prefabricated Buildings Based On SEM And Evolutionary Game

Promoting prefabricated buildings can help accelerate the transformation and upgrading of the construction industry and improve the contribution of the construction industry to the goal of "carbon peak".However,at this stage,the results of the promotion of prefabricated buildings in China are not significant,and the problems of insufficient development momentum of prefabricated buildings and the failure of the prefabricated building market have seriously restricted the promotion of prefabricated buildings in China.Solving the problems of insufficient development power of prefabricated buildings and market failure of prefabricated buildings has certain reference significance for promoting the promotion of prefabricated buildings.This study defines that the main body of prefabricated buildings are developers,governments and consumers,and uses the theory of innovation diffusion,grounded theory and planned behavior theory to find the driving factors for promoting prefabricated buildings.On this basis,the structural equation model(SEM)of prefabricated building promotion is established,and the Amos software is used to study it,and there are 15 paths to promote prefabricated buildings,of which the path "developers develop prefabricated buildings→ prefabricated building promotion" is the key direct path of prefabricated building promotion,and the path、 "consumers buy prefabricated buildings → developers develop prefabricated buildings →prefabricated buildings promotion" is the key indirect path of prefabricated building promotion.In order to further strengthen the promotion of prefabricated buildings,this paper starts from the critical path of prefabricated building promotion,establishes a developer-consumer evolution game model,and uses Matlab software to simulate the key parameters affecting the system evolution game.It is concluded that reducing the incremental cost for developers to develop prefabricated buildings,increasing the cost saved by developers to adopt prefabricated construction technology,and increasing the government’s incentives and subsidies to developers can fundamentally promote the sustainable development of prefabricated buildings.Based on this,this paper puts forward relevant suggestions for developers and the government.Developers can take advantage of objective conditions and improve development capacity to reduce development costs and increase the cost savings.The government can formulate reasonable economic incentives and subsidies policies and strengthen the implementation of economic policies for prefabricated buildings to strengthen the implementation effect of government economic incentive policies.This study provides a direction for stimulating the vitality of the main body of the prefabricated building industry chain,and provides a focus for the government to strengthen the guidance of prefabricated buildings under the condition of limited government resources,which is conducive to expanding the scale of the prefabricated construction industry and promoting the development of prefabricated construction process.
