This paper constructs the evaluation index system of technology introduction ability. Based on this index system, the multi-element cluster analysis method is used to classify the technology introduction ability of northeast old industrial base and the technology introduction ability of developed provinces and cities. And to find out the weakness of the technology introduction ability of the northeast old industrial base. To improve the technological imitation of the innovation ability of the northeast old industrial base, it has provided countermeasures and suggestions to enhance the innovation ability of the three northeastern provinces to imitate the innovation ability and improve its regional autonomy Innovation ability to provide theoretical reference.
