The current body of literature indicates that the utilization of emerging digital safety technologies has the potential to enhance the efficacy of safety management in construction significantly. Nevertheless, there has been limited uptake of digital safety technologies within the construction industry in developing countries. This study is focused on evaluating the adoption of digital safety technologies in construction specifically from the perspective of developing countries. Questionnaire data were gathered from project management professionals in China and subjected to analysis using mean ratings, factor analysis, and fuzzy composite evaluation. The developed model for assessing safety technology adoption comprises four primary criterion groups about factors influencing adoption, namely organizational, technological, individual, and external categories. The study results indicate that factors within the technology category exert the most significant influence on the adoption assessment model, followed by those in the external and organizational categories, and finally by individual category factors. These findings contribute to advancing the theory of digital technology adoption in construction safety management research within developing countries. Practitioners can utilize this information to effectively evaluate and compare success rates of safety technology adoption, thereby informing management decisions required for projects. The insights provided by this study will equip practitioners with scientific knowledge for more effective and sustainable program management, ultimately enhancing the success of safety technologies.

Urban expansion intensifies economic–environmental conflicts, making human settlement quality increasingly critical for sustainable development. This study applies ecological niche theory to evaluate the evolution of human settlement quality in the Wuhan Metropolitan Area (WMA) from 2014 to 2022 using 21 economic, social, and ecological indicators. The results reveal: (1) significant variations in niche-fitness values across subsystems, with Wuhan maintaining superiority (>0.820) despite a gradual decline, while peripheral cities—notably Huangshi, Tianmen, and Ezhou—consistently ranked lower (<0.610) throughout the study period; (2) three evolutionary trajectories emerged, characterized by continuous decline, inverted U-shaped development, and sustained growth, reflecting nonlinear dynamics and path dependence in the region’s development patterns. These findings underscore persistent core-periphery disparities within the metropolitan area, yet improved regional coordination is evident as inter-city evaluation gaps narrowed from 0.329 to 0.231 between 2014 and 2022. Based on these insights, tailored policy recommendations are proposed to address the identified disparities and promote balanced development. This study offers valuable theoretical and practical contributions toward achieving coordinated and sustainable development in metropolitan regions.

Prefabricated building construction is a crucial approach to achieving “green” building goals, yet it differs significantly from traditional cast-in-place construction methods. Due to complex cross-operations, high mechanization requirements, insufficient worker experience, and inadequate safety measures, prefabricated construction faces greater safety management challenges than traditional methods. This study identifies 17 key indicators influencing unsafe behaviors among prefabricated building construction workers across four dimensions: physical environment, individual factors, team factors, and safety management. A combined weighting method, integrating the entropy weight method and the coefficient of variation method, was employed to determine the weight of each factor. Based on the weight analysis results, a system dynamics intervention model for unsafe behaviors of prefabricated building construction workers was developed and simulated using the Vensim platform. The results indicate that, among single intervention measures, improving individual comprehensive skills has the most significant effect, reducing unsafe behaviors by 37.78%, though this still falls short of the desired target. In contrast, combined interventions yield superior outcomes, with reductions of 68.87% for individual factor interventions, 59.93% for safety management interventions, 46.32% for team factor interventions, and 20.71% for physical environment interventions. These findings highlight the significant advantages of combined interventions. Based on the study results and the characteristics of prefabricated construction, this paper proposes specific intervention strategies, emphasizing the importance of training and institutional development to systematically enhance workers’ safety behaviors.
