Analysis of Influencing Factors of Urban Infrastructure Disaster Response Behavior Based on Protection Motivation Theory
In recent years,disaster prevention and mitigation of urban infrastructure has received ex-tensive attention and high priority at home and abroad,and research on disaster risk assessment and emergency response has also become a hot issue.The limitation of risk knowledge and the differences in decision makers'risk perception all constrain the performance of emergency response functions.In order to enhance the risk perception acuity of infrastructure managers and improve the emergency re-sponse efficiency,this study adopted Partial Least Squares Structural Equation Modeling(PLS-SEM)to investigate the main factors affecting managers'disaster response behavior.Firstly,the model was constructed based on relevant literature and theories.Secondly,the model was tested by analyzing 196 valid questionnaire data.The results show that the disaster experience of managers is significantly neg-atively correlated with risk perception and significantly positively correlated with self-efficacy.Mean-while,managers'disaster experience and knowledge level will significantly affect response behavior through the mediating role of self-efficacy.According to the findings of the study,recommendations were put forward to guide managers to adopt disaster response behaviors.
