本文从价值链、企业链、供需链和空间链出发，综合运用层次分析法和熵权法构建指标体系，对辽宁省高技术产业链安全水平进行评估。结果显示，2010~2023年辽宁省高技术产业链安全水平波动上升，细分行业表现存在差异。未来辽宁省应立足现有优势，聚焦短板弱项，强化自主创新能力，推动高技术产业链安全发展。

This paper construct an indicator system by comprehensively utilizing AHP and entropy weight method to evaluate the security level of Liaoning’s high-tech industry chain including value chain, enterprise chain, supply and demand chain, and spatial chain. The results show that the security level has fluctuated and increased from 2010 to 2023, and the performance differs across sub-sectors. To promote safer development, Liaoning should leverage existing advantages, focus on shortcomings, strengthen independent innovation capabilities.
