The invention provides an airport group event evolution state determination method, apparatus and device, and a medium. The method comprises the steps of determining a target undirected graph based on real-time multi-modal behavior feature vectors of a plurality of airport passengers; calculating a sub-group condensation degree based on edges in the target undirected graph, determining a sub-group in the target undirected graph, and if the sub-group is evolved and updated, updating a state feature vector of the sub-group; determining a real-time state feature vector sequence of the group events based on the state feature vectors of the sub-groups at the current moment, and inputting the real-time state feature vector sequence of the group events into a time sequence loop network to form a fusion state feature vector of the group events; and inputting the fusion state feature vector of the group events into an airport group event evolution state classification model, and outputting the evolution state classifi
