The invention provides a prediction method and optimization method for the full-length deformation resistance of cold continuous rolling strip steel, and belongs to the field of metallurgical rolling. According to the method, based on strip steel cold rolling historical production data, the deformation resistance of each cold rolling rack is solved, then parameters of a deformation resistance equation are solved through fitting, and a training set and a verification set are constructed; constructing a strip steel full-length deformation resistance prediction model, collecting a training set to train the model, taking hot rolling historical production data as input, taking parameters of the deformation resistance equation as output, training and verifying to obtain a mature prediction model, collecting current strip steel hot rolling production data, and inputting the data into the mature prediction model; and outputting a full-length deformation resistance prediction result of the current strip steel, establi
