Study on the operational efficiency of prefabricated building industry bases in Western China based on the DEA model

Prefabricated building industry bases emerged at exactly the right moment, and therefore coincided with the transformation and upgrade of the construction industry and the rapid development of urbanization, but the analysis of the process through which prefabricated buildings develop often neglects the actual operating efficiency of prefabricated building industry bases. This is due to differences between the western region and other regions that relate to, inter alia, policy, technology level, standard specification, and market demand. The study of the operational efficiency of prefabricated building industry bases in the western region is therefore of great significance. This paper uses a literature review and expert correction to establish an input–output index system. It also conducts field research in different regions and uses the Data Envelopment Analysis (DEA) research method to analyze overall differences between prefabricated building industry bases in Western China and other regions. It also draws on macro and micro perspectives to assess problems that exist in their own operations. In conclusion, it provides four targeted suggestions that operate from within government and base investor perspectives.
