Incentive Mechanism of BIM Application in Prefabricated Buildings Based on Evolutionary Game Analysis

Prefabricated buildings have become a key area promoted in the new urbanization. Implementing BIM is one of the crucial supports for accelerating the development of prefabricated buildings. In order to effectively promote the development of BIM+ prefabricated buildings, this paper establishes an evolutionary game model between the government and prefabricated construction enterprises. The replication dynamic equation is employed to analyze the strategy choices of both participants, and the Matlab simulation is adopted to explore the evolution process of enterprises to actively use BIM. Results show that the application of new technologies can be effectively promoted by increasing the unit price of carbon trading, enlarging the tax rate difference, advancing technology, improving the level of enterprise effort, and enhancing social awareness to reduce the payment-to-income ratio of enterprises using BIM. Additionally, reasonable administrative measures, policy subsidies and fines will also positively affect government incentives and the strategy choice of enterprises using BIM. Therefore, a reasonable government incentive system can promote the development of BIM+ prefabricated buildings to a certain extent.
