Abstract：Accurately identifying the list of“bottleneck”technologies,distinguishing their relative urgency and severity,and optimizing the allocation of scientific,technological,and societal resources are of great significance for achieving independent and controllable development of China's critical and core technologies,and for building a modernized industrial system.Grounded in the characteristics of“bottleneck”technologies,this study develops a four-dimensional progressive model based on criticality,technological weakness,monopoly intensity,and difficulty.By applying complex network analysis,the model captures the interrelationships among technologies within the technological system,highlighting the central role of bottleneck technologies.Furthermore,the incorporation of an indicator-based construction method ensures the accuracy and practical operability of the identification results.Based on granted invention patents in the core electronics industry,eight severe and two potential“bottleneck”technologies were identified.The results correspond with international competitiveness priorities in the sector,confirming the validity and reliability of the proposed four-dimensional identification model.
