| 摘 要： | 目的/意义] 从专利分类修订角度研究技术演化，为技术演化研究提供新思路。方法/过程] 首先根据IPC分类表H部2009-2018年的修订情况，总结出新增分类、删除分类、类内转移分类、类间转移分类4种修订类型。其次针对分类修订后产生的过档文献提出基于Word2vec+TextCNN模型的过档文献再分类方法，使新旧版分类表通过再分类专利产生衔接。最后结合H部2009年-2018年被修订分类及再分类专利进行技术演化初步探索。结果/结论] 专利再分类模型可有效解决过档文献问题，为专利再分类工作提供参考，同时可衔接新旧版专利分类表；结合IPC分类修订及再分类专利可分析分类修订中的主要技术演化方向，为技术演化研究提供新视角。

| Abstract: | Purpose/significance] This article attempts to study technological evolution from the perspective of patent classification revisions, and provides new ideas for technological evolution research. Method/process] First, according to the 2009-2018 revisions of the H part of the IPC classification table, four types of revisions were summarized: new classification, deletion classification, intra-class transfer classification, and inter-class transfer classification. Secondly, for the archived documents generated after classification revision, a reclassification method of patent archived documents based on the Word2vec+TextCNN model was proposed, so that the old and new classification tables were connected by reclassifying patents. Finally, combined with the revised classification and reclassification patents of Part H from 2009 to 2018, the preliminary exploration of technological evolution was carried out. Result/conclusion] The patent reclassification model can effectively solve the problem of archived documents, provides reference for patent reclassification work, and can link the new and old patent classification tables; based on IPC classification revision and reclassification of patents, the main technological evolution direction after classification revision can be analyzed, providing a new perspective for research on technological evolution. |
