| [Purpose/Significance] The mining of technological innovation opportunities is closely related to actual technological needs. However, these two aspects are often treated separately in existing research. Constructing a technology opportunity identification framework that integrates technological needs can enable efficient technology mining and systematically identify potential technological innovation opportunities. [Method/Process] A framework based on the Technological Innovation System (TIS) theory is constructed to identify technological innovation opportunities in the blockchain field. The framework begins by extracting blockchain-related patents from the PatSnap database. At the technological needs layer, the background technology sections of patents are analyzed using LDA topic clustering to identify key technology demand themes. At the technology exploration layer, a lightweight BERT algorithm combined with the LOF algorithm is employed to detect potential weak technological signals. At the technology assessment layer, multiple innovation opportunity indicators are constructed to evaluate the potential value of these weak signals. Ultimately, technological innovation opportunities in the blockchain field are summarized. [Result/Conclusion] Technological needs in the blockchain field are concentrated in eight key areas, including consensus algorithms. Future technological innovations are expected to focus on decentralization, cross-chain interoperability, and related directions. The research findings can provide targeted decision-making support for enterprise R&D and government policy formulation. |
