The invention discloses an integrated optimization method for dynamic allocation and operation plans of subway passenger and freight shared carriages by taking a single urban rail transit line as a research object. Factors such as arrival time of passengers and cargoes, OD of the passengers and the cargoes, arrival and departure time of the train, capacity of the train, use authority distribution of passenger and cargo shared carriages and the like are comprehensively considered, a train operation plan can be collaboratively optimized according to passenger and cargo demands, and dynamic distribution of train resources in an operation period is realized, so that timeliness and high efficiency of transportation are achieved. Specifically, a 0-1 auxiliary variable is adopted to represent the use state of the passenger and freight shared compartment, the relation between an actual loading object of the passenger and freight shared compartment and the auxiliary variable is established, an original problem is conv
