中文摘要：

由于当前技术机会识别方法难以支撑不断涌现的技术创新需求,文章提出了基于专利挖掘与形态分析的技术机会识别路径,并以3D打印机为例对其进行应用分析。通过专利信息服务平台对3D打印机专利进行检索及聚类,判别打印机喷头、打印技术以及打印材料3种要素的类别,进而构建了形态矩阵,结合熵权法筛选出技术创新机会。计算分析结果显示切换式多色打印机头、激光烧结、复合材料的组合为最佳方案。

英文摘要：

Because the current identification methods of technology opportunities are still not enough to support the emerging needs of technological innovation,this paper proposes the path of technology opportunities identification based on patent mining and morphology analysis,and takes 3D printer as an example to carry on the empirical analysis. This paper searches 3D printer and makes clustering analysis through patent information service platform so as to discriminate the categories of printer nozzle,printing technology and printing materials. Then the paper constructs the shape matrix,which is combined with the entropy method to screen new technology innovation opportunities. The calculation and analysis result shows that the combination of the switching type multicolor printer nozzle,laser sintering,and the composite material is the best solution.
