Urban Development Potential Evaluation of Prefabricated Buildings Based on PCA-TOPSIS Model

In recent years, with the strong support of the Chinese government, prefabricated buildings have entered a period of rapid development. Prefabricated buildings occupy an important position in the construction industry in China. However, in the process of the implementation of prefabricated buildings, it is found that each region has different economic, technological and social levels, and each city has different development strategic goals and related supporting policies. The development potential of prefabricated buildings is very different, the development process is different, and the potential needs to be tapped. Based on the literature research method, this paper selects 25 evaluation indicators from four aspects of policy, economy, technology and market, adopts the principal component weighted TOPSIS evaluation method to construct a comprehensive evaluation model of the development potential of prefabricated buildings in cities, and makes a comprehensive evaluation of the development potential of prefabricated buildings in cities, so as to help cities understand their own development potential of prefabricated buildings. Develop prefabricated building development strategy to provide reference.
