Abstract： [Purpose/Significance] “Neck Stuck” technology is the key point that restricts the high-quality development of China’s strategic emerging industries at the present stage. To ensure the independent security control of the industrial chain, it is necessary to identify the “Neck Stuck” technology efficiently and accurately. [Method/Process] This study utilizes patent literature as the main data source. Firstly, key core technologies are selected based on technical co-occurrence network measurements. Secondly, the relationship between latecomer advantages and independent innovation capabilities is comprehensively considered from the perspective of technical gaps and technical-economic security. A “Neck Stuck” technology identification index system is designed across four dimensions: technical value advantage, technical competition advantage, technical monopoly status, and independent controllability. Then, a systematic “Neck Stuck” technology identification model is constructed using the CRITIC-TOPSIS method. Finally, empirical research is conducted in the field of numerical control machine tools. [Result/Conclusion] The results of the identification process using the proposed method in this study reveal the existence of 34 potential “Neck Stuck” technologies in the field of numerical control machine tools in China. These technologies are primarily concentrated in the control or adjustment system, key functional components, turning or boring numerical control machine tools, and digital data processing. A comparison of these findings with the U.S. Commerce Control List confirms the high degree of consistency, thus validating the feasibility and reliability of the proposed method.
