In view of the practical problems existing in the allocation of airport emergency resources and the characteristics of airport safety management, considers the overall relative efficiency of input and output in the airport emergency system, selects emergency personnel funds, machinery and equipment funds as input indicators, sudden time loss value and emergency event compliance rate as output indicators, and uses data envelopment analysis (DEA) The efficiency of emergency resource allocation of 9 airports in Jiangsu Province was studied. The results show that only two airports in Jiangsu achieve DEA effective, and the returns to scale of six airports are decreasing, and four of them are scale mismatching. This paper puts forward some suggestions for the improvement of non DEA effective airports and the future development of Jiangsu airport emergency resource allocation, so as to improve the efficiency of airport emergency resource allocation and reduce the waste and idle of resources.
