This study seeks to explore the impact of safety perceptions on spatial allocation decisions within the construction supply chain in China, with particular emphasis on the mediating role of risk management strategies. By examining the interrelationships between safety perceptions, risk management strategies, and spatial allocation decisions, the research aims to provide valuable insights into the factors shaping safety management practices and spatial planning processes in construction projects. A quantitative research design is employed in this study, using a structured questionnaire to gather data from employees and managers working in construction companies across China. The questionnaire is administered in three stages (T1, T2, and T3), and the data are analysed through statistical methods, including correlation analysis, regression analysis, and mediation analysis. The results of the study reveal significant associations between safety perceptions, risk management strategies, and spatial allocation decisions within the Chinese construction supply chain. Notably, risk management strategies—such as the quality of risk assessments, resource allocation for safety, safety training programmes, and emergency response planning—are identified as key mediators in the relationship between safety perceptions and spatial allocation decisions. This research contributes to the existing literature by offering empirical evidence on the connections between safety perceptions, risk management strategies, and spatial allocation decisions within China's construction industry. By addressing critical gaps in current knowledge, the study provides practical recommendations for construction firms, policymakers, and researchers aiming to improve safety outcomes and optimise spatial planning processes in construction projects.
