In recent years,the state and Xi'an have issued a series of documents to vigorously promote the development and construction of prefabricated residential buildings with energy saving,environmental protection,labor saving and sTab.quality and performance.However,prefabricated residential buildings are slowly being promoted in China and Xi'an.The research on prefabricated buildings is increasing,but the research on the economic evaluation that hinters developers from making investment decisions on prefabricated buildings is Iess.There fore based on the real estate project on the basis of economic evaluation theory and system dynamics theory,from the perspective of developers,the construction of the prefabricated housing economic evaluation model based on system dynamics,to Xi'an prefabricated housing project as an object for research,selected the influencing factors of xi"an prefabircated housing project economics,application system modeling method,the combination of quantitative and qualitative methods to evaluate Xi'an prefabricated housing project economic feasibility study.(1)On the basis of domestic and foreign research and summary,Xi'an prefab housing characteristics and relevant theories of project economic evaluation,this paper constructs the prefab housing economic evaluation index system and analyzes the component indexes.(2)Combining the economic evaluation index and content of prefabricated house,the feedback graph model of prefabricated house project economic evaluation is established by using system dynamics simulation software VENSIM.On this basis,the factors in the system are quantitatively analyzed and the built-in function is carried out to obtain the economic evaluation model of Xi'an prefabricated house project.(3)Based on VENSIM software,the economic evaluation model of Xi'an prefabricated housing project was used to simulate XX project in Xi'an.By analyzing and discussing the simulation results,the economic evaluation model of prefabricated house in Xi'an is proved to be operable and reliable.At the same time,three parameters of prefabrication rate,interest rate and selling price were set for simulation under different circumstances and simulation results were analyzed.Finally,according to the simulation results,the author puts forward some Suggestions on how to determine the range of prefabrication rate and how to improve the economic benefit of the prefabricated housing project in Xi'an,and how to promote the prefabricated housing project in Xi'an by the government.Xi'an prefabricated housing economic evaluation model not only makes economic feasibility evaluation for prefabricated housing projects,but also realizes dynamic analysis and evaluation,that is,helps developers and companies make scientific and accurate investment decisions and development strategies for prefabricated housing projects.Thereby increasing the promotion of prefabricated residential buildings in Xi'an and at the same time contributing to the development of prefabricated residential buildings in China.
