专利间知识流动与技术融合趋势研究

通过专利引用关系研究技术交叉融合趋势，进而发掘主流技术领域和新兴领域具有现实意义。考虑到目前专利技术边界划分的片面性、技术融合过程缺乏对时间因素的考虑，提出一套结构化的技术融合分析方法。利用产业与专利的映射关系，构建不同技术领域间知识流动矩阵；从技术溢出、技术影响两个维度，构建技术融合趋势图，刻画出4种不同的技术融合类型，并通过时间序列分析技术融合的动态过程。以国家知识产权局新能源汽车专利数据为例，验证了方法的可行性，发现技术融合过程存在明显的技术邻近性，并且技术融合角色呈现动态变化。

Trend Research for Knowledge Flows of Patents and Trends of Technology Fusion

It is of practical significance to research the cross integration of technology through the citation between patents, considering the one sidedness of the current technology boundary division and the lack of dynamic analysis of the technology integration process, presents a procedural method to analyze trends of technology fusion.First, the concordance between industry and patent is employed to construct the knowledge flow matrix, and then comprehensive assessment indicators have been established from two dimensions of technology spillover and technology influence, and 4 kinds of different types of technology fusion are depicted; the dynamic process of technology fusion by time series analysis.Finally, it takes the green car patent data by State Intellectual Property Office, to verify the effectiveness of the procedural method.The result reveal that there is a clear technical proximity in the process of technology fusion;the technology fusion role will change dynamically.
