基于专利分析的视角,利用Citespace分析工具结合专利综合指数分析方法,引入技术突现率、技术重复率、技术中心度水平、技术综合性指数等指标,构建技术发展趋势研究模型,通过分析得出特定技术领域的研究热点和技术机会,还原技术发展路径,从而预测技术发展趋势。最后对汽车尾气净化技术发展趋势进行了实证分析,验证了该分析模型的可行性。

Based on the perspective of patent analysis, with Citespace and patent composite index analysis method, introduced indices such as technology emergence rate, recurrence rate, level for the degree of technology center and technical comprehensive index to build the research model for the technology development trend. Through the analysis of the specific technology field to summarize the research hotspot, technology opportunity and technology development path and then achieve the goal of predicting the technology development trend. Finally,carried the empirical analysis on the technology development trend of the automobile exhaust purificationSfield to verify the feasibility of the analysis model.
