Measuring the Factors that Influence the Diffusion of Prefabricated Construction Technology Innovation

Prefabricated construction (PC) is considered to be a solution for construction unsustainability. Promotion of PC is based on measuring the influencing factors for the diffusion of prefabricated construction technology innovation (PCTI). Therefore, this study explored the influencing factors and underpinned mechanism for the diffusion of PCTI from the perspective of construction enterprises’ adoption, with two dimensions of internal and external. A conceptual model with nine hypotheses was first established. Then, this study conducted a questionnaire survey of 119 construction enterprises across the PC industry, and made an empirical analysis using structural equation model (SEM), to test the model. The results found that both construction enterprises and governments play significant roles in the diffusion of PCTI while agencies and consumers do not. Besides, network power of construction enterprises plays a mediating role in the relationship. This study provides decision-making assistances for different stakeholders in the PC industry.
