Abstract
In recent years, the development of prefabricated building (PB) mode in China has gradually attracted the attention of stakeholders. It is of great significance to explore the adoption behavior of PB mode by Chinese construction enterprises. Using the method of combining evolutionary game theory with system dynamics and considering the multiagent interaction of the government, construction enterprises, and consumers, as well as the influence of multiple factors, this paper constructs a model of construction enterprises' adoption behavior of PB mode. The purpose is to clarify the mechanism of Chinese construction enterprises' adoption behavior of PB mode and the evolution law of market share. The research results show the following. Firstly, government subsidy plays an important role in promoting the maturity of PB market, but it plays a relatively small role in the more mature and stable market. Secondly, the higher the initial acceptance probability of the construction enterprise, the greater the peak of the PB market share and the greater the volatility, but it has no differential impact on the balance of the PB market in the later stage. Thirdly, price factors and quality factors, respectively, have an important impact on the increase of the PB market share in the early and late stages of the formation of the PB market, but the delivery waiting time factor has no significant impact on the PB market share.
Highlights
The application and promotion of prefabricated building (PB) mode in China faces many obstacles
Some scholars believe that the government plays an important role in the process of whether the PB mode is adopted by the construction enterprise [5]
As the investor of a construction project, the construction enterprise’s behavioral willingness and adoption behavior are highly correlated [20]. erefore, whether the construction enterprise adopts the behavior and decision making of PB mode is very important for the development of the PB industry. e construction enterprise will make reasonable decisions on its own construction mode based on the economic benefits, environmental performance, maintenance cost, and other factors of the construction project [21, 22]
Summary
E model types of the payoff module of the construction enterprise that selects the “DY” strategy (UDY ) and the “DN” strategy (UDN) are similar. E consumer decision-making module mainly characterizes the consumer’s purchase decision for TB or PB, and its purchase decision mainly considers the price, construction quality, and delivery waiting time of construction products. E delivery waiting time sensitivity distribution model is used to measure the extent to which the delivery time of different building modes affects consumers’ motivation to purchase the product. Based on the above three modules, the system dynamics model of PB mode adopted by Chinese construction enterprises is established. After reaching the peak, the construction enterprises that adopted PB mode fluctuated in the form of shocks and eventually decreased gradually at a lower rate
