A Dynamic Evaluation Method for the Development of Intelligent Construction Technology in the Construction Field Based on Structural Equation Model-System Dynamics Model

In order to explore the development trends of intelligent construction technology in the field of construction, this paper constructs a system dynamics (SD) model of the application and development of BIM and the new-generation information technology in the construction industry based on SD theory and a structural equation model (SEM). Vensim DSS is used to explore the relationship between the SD model and six subsystems. The dynamic simulation and the sensitivity analyses are also conducted. Results show that during 2023-2050, as the time series advances, the effect value of the dynamic simulation gradually increases. From 2035, intelligent construction technology shows a trend of rapid development between various subsystems and the SD model. The adjusted model and the status of the subsystem are consistent with the SD model simulation curve. It is verified that intelligent construction technology has good development prospects in the construction field.
