Risks hinder the role of prefabricated construction (PC) in promoting construction automation. Although existing research has focused on risk management (RM) in PC, the lack of a global perspective has affected the effectiveness of RM. Accordingly, this paper adopts a scientometric analysis to review the knowledge domain of RM in PC. A total of 144 articles were selected from the Scopus database for journal citation analysis, document co-citation analysis, and keyword co-occurrence analysis. The results show that since 2011, the annual publications show an overall upward trend. International Journal of Construction Management, Journal of Building Engineering, and Buildings have been cited more frequently recently. PC research, RM research, environmental sustainability research, and ergonomic research provide a solid foundation for the research on RM in PC. Existing studies are conducted from five knowledge themes, namely, Supply chain and industry, Decision and optimization, Safety and health, Environment and overheating, and Investment and cost. Further, current research content, future research needs, and RM strategies for PC practices are discussed. This study helps stimulate further promising research and enhance the effectiveness of RM in PC in practice.

PurposeInsufficient intra-organizational diffusion of prefabricated construction (PC) technology hinders its implementation benefits. More research on intra-organizational diffusion of PC technology is required to improve organizational performance in PC implementation. This study aims to explore the antecedents and consequence of intra-organizational diffusion of PC technology.Design/methodology/approachThis study established an antecedent and consequence model of intra-organizational diffusion of PC technology from the perspective of contingency theory. The model was empirically tested by 91 valid questionnaires using partial least squares-structural equation modeling (PLS-SEM).FindingsThe results indicate that organizational support (OSU), organizational climate (OC) and mechanistic organizational structure (OST) positively influence intra-organizational diffusion of PC technology, which further positively influences organizational performance. The relationship between OC and intra-organizational diffusion of PC technology is mediated by OSU. Technological turbulence negatively moderates the relationship between OSU and intra-organizational diffusion.Originality/valueThis is the first paper to study the antecedents and consequence of intra-organizational diffusion of PC technology and an expansion of contingency theory in the research field of PC technology. This study helps to theoretically stimulate future research on intra-organizational diffusion and practically promote intra-organizational diffusion of PC technology along with improving organizational performance in its implementation.
