随着社会经济飞速增长，技术发展日新月异，致使技术创新模式发生重大变革。之前对技术发展趋势分析多数局限于定性和定量的研究。因此，本文创新性的引入SAO结构分析方法，利用相关软件挖掘出专利的SAO结构，并据此设计算法计算专利之间相似度，结合专利地图分析相关技术的发展方向及趋势，形成基于专利数据的技术发展趋势研究框架。最后以液晶材料技术为例，进行了实证研究，技术重点已经由基础技术的研发转向更高效、成本低的大规模的材料研发。这些研发背景为企业制定发展战略和了解技术进步提供理论基础。

With the rapid growth of the social economy and the rapid development of technology, major changes have taken place in the technological innovation model. Previous analysis of technology trends was mostly limited to qualitative and quantitative research. Therefore, this paper introduces the SAO structure analysis method innovatively, and uses the relevant software to mine the patented SAO structure, and based on this design algorithm to calculate the similarity between patents, combined with the development direction and trend of patent map analysis related technology, forming patent-based data. Research framework for technology trends. Finally, using liquid crystal material technology as an example, an empirical study has been carried out. The technical focus has shifted from the development of basic technology to the development of large-scale materials with higher efficiency and lower cost. These R&D backgrounds provide the theoretical basis for companies to develop their development strategies and understand technological advances.
