To gain a deep understanding and evaluate the command capability and current status of counties in response to flood disasters，this paper identified 12 major influencing factors through literature analysis. Social network analysis was conducted using Ucinet software，and Netdraw software was utilized for visualization to depict the social network relationship diagram among these influencing factors. By calculating the in-degree and out-degree，as well as centrality of the influencing factors，indicator classification was performed. Drawing on the maturity model of command and control capability，an assessment model based on social networks for the maturity of county-level flood disaster emergency command capability was developed. Puyang county was selected as the empirical research object. Through questionnaires and interviews，a total of 342 data entries from 24 townships in Puyang County were collected to evaluate the county's flood disaster emergency command capability. The results indicate that it is feasible to classify indicators hierarchically through social network analysis. The established indicator system is scientifically and accurately reflected in the comprehensive operational level of county-level flood disaster emergency command. The assessment model can effectively evaluate the maturity levels of emergency command capability.
