In the daily operation of city gas pipelines, due to the characteristics of the gas itself and the influence of the environment in which the pipeline is located, leakage accidents are prone to occur and cause serious consequences. When the gas pipeline leaks, the accident is handled according to the emergency plan, and the emergency resources are an important part of the emergency plan, and the complete emergency resources can well reduce the maintenance time, thereby reducing the economic losses caused by the leakage accident. In order to improve the utilization rate of emergency resources for urban gas pipeline leakage accidents, reduce their redundancy, and improve the efficiency of emergency repair. The purpose of this study is to evaluate the efficiency of emergency resource allocation for third-party damage leakage accidents in city gas pipelines by combining DEA models. Through the analysis of the efficiency values, the under-investment or redundancy of each gas company's resource allocation is found, and corresponding suggestions are made to improve the gas company's emergency response capability for gas leakage accidents and to provide a reference basis for the emergency resource allocation for urban gas pipeline leakage accidents.
