Abstract: Objective To understand the relationship and pathway between occupational burnout,organizational justice,and health emergency response capability,providing a scientific basis for improving the health emergency response capacity of port personnel. Methods From February to May 2024,the Cochrane formula was used to calculate the sample size,and a simple random sampling method was selected according to the nature of the work of the port personnel. An anonymous questionnaire survey was conducted on 524 staff members in 21 agencies within the ports of Tianjin,which included the occupational burnout scale,the sense of organizational fairness scale,and the health emergency response work competence scale,and the data were analyzed. Results The burnout score of the port personnel in the 21 agencies within the Tianjin port was （39.47±10.36）points,the organizational fairness score was （74.15±10.80）points,and the health emergency response work capacity score was （98.11±17.57）points. Burnout was negatively correlated with health emergency work competence（r=-0.245,P<0.05）,and burnout could explain 5.8% of the variation in health emergency work competence. Sense of organizational fairness was positively correlated with health emergency work competence（r=0.396,P<0.05）,and sense of organizational fairness could explain 15.5% of the variation in health emergency work competence. The mediating effect value of sense of organizational fairness on burnout and health emergency work competence was -0.314. Conclusion Occupational burnout has a negative predictive effect on health emergency response capability,while organizational justice has a positive predictive effect on health emergency response capability. Organizational justice plays a full mediating role in the relationship between occupational burnout and health emergency response capability.
