Abstract

[Purpose/Significance] Constructing an industrial technology chain risk measurement method and systematically evaluating the risk evolution trajectory over a long period can provide a methodological reference for breaking through the “bottleneck” dilemma of key core technologies. [Method/Process] Starting from the connotation characteristics of the industrial technology chain and technology gap theory, this study constructed a three-dimensional risk framework of “technology level-technology value-technology complexity”(LVC), and proposed a competitiveness index and risk index measurement method integrating Entropy Weight-TOPSIS based on this. It quantitatively identified the advantages and disadvantages of each link of the technology subjects, and revealed the risk differences and time-series evolution trajectories of different subjects from the perspective of the overall technology chain and technology links. [Result/Conclusion] Taking the “New Energy Vehicle” industry as an example, the empirical results show that the measurement method based on the LVC three-dimensional risk framework can significantly improve the dimensional completeness and decision-making support of the industrial technology chain risk assessment. This study expands and deepens the theory and measurement methods of industrial chain risks, and provides scientific support for the optimization of industrial technology policies, forward-looking technology layouts and technology chain security governance.
