Influence factors of construction enterprises'willingness to apply digital technology in safety management
From the perspective of construction site safety management,this study explores the main factors affecting the application of digital technology in construction enterprises and the influence degree of each factor.Based on the Technology Acceptance Model(TAM)and Technology-Organization-Environment(TOE)framework,the study establishes a system dynamics model to analyze construction enterprises'willingness to apply digital technology in safety management.Through literature analysis and semi-structured interviews,15 influence factors in 4 dimensions are identified.Furthermore,the system boundary values for each influencing factor are calculated.According to the interaction between dimensions and influence factors,the causal diagrams and flow and stock diagrams of the system are constructed.Subsequently,this study uses the G1 weighting method and the entropy method,considering subjective weights,objective weights,and comprehensive weights,to assess the significance of each factor and dimension within the system.Finally,system equations are constructed and Vensim PLE software is used to take simulation of the system.The analysis results show that the willingness of construction enterprises to apply digital technology in safety management is a complex dynamic system.In the initial simulation,all four dimensions collaboratively promote the growth of the overall application intention,with organizational and perceived effectiveness dimensions exhibiting greater influence than the technology and environmental dimensions.Furthermore,the results of dimension sensitivity analysis reveal that the organizational dimension and the environment dimension sensitivity are greater than the perceived effectiveness dimension and the technology dimension,and the impact on the application intention system is more obvious.After the sensitivity analysis of the influence factors one by one,it is found that the most sensitive influence factors in each dimension are perceived usefulness,enterprise importance,technology optimization,and policy support,indicating that the change of application intention is more obvious when they change,and they belong to the key influence factors in the system.
