Construction and Empirical Analysis of Influencing Factor Index of Prefabricated Construction Cost

The transformation of China’s construction industry is in a period of rapid development, especially the rapid development of prefabricated buildings, but the lack of effective cost control and management, resulting in a substantial increase in its cost, has become a bottleneck restricting its development. Based on the analysis of the composition of the prefabricated construction cost, the paper makes use of the literature and case data to analyze, thus establishing the index system of the influencing factors of the prefabricated construction cost. On this basis, a questionnaire is designed, and SPSS software is used to make an empirical analysis of the influence of various factors on the cost of prefabricated buildings, and the corresponding cost control strategies are given from the perspectives of design, production, transportation, installation and other five aspects.
