Research On The Influence Of Industrial Policy On The Development Of Prefabricated Buildings In Nanjing: Empirical Analysis Based On System Dynamics

In order to explore the effectiveness of the industrial policy of prefabricated construction, this article constructs a system dynamics model of Nanjing's prefabricated construction industry policy. The data from 2005 to 2019 is used to carry out a dynamic simulation of industrial policy to compare and analyze the simulation results of industrial policy. In addition, heterogeneity testing and counterfactual testing were used to verify the reliability of the model and results. Results indicate that the industrial policy issued by Nanjing has a significant role in promoting the development of the prefabricated construction industry. This kind of promotion effect is accumulative, that is, the earlier the same industrial policy is introduced, the more obvious the promotion effect on the prefabricated construction industry. From the perspective of research tools, system dynamics is a more suitable tool to quantify the complex relationship between research policies and the development of the construction industry. The results of system authenticity test and counterfactual test also show that the framework of the comprehensive research system of the prefabricated construction industry constructed in this study is of good feasibility. It provides a reference for further quantitative research.
