摘要
文章基于专利共类信息,从整体和局部视角构建技术融合的分析框架。整体层面分析技术领域融合分布和年度变化,利用领域共现分析领域间融合程度。局部层面利用计量学指标(共现频次、中介中心性和突发指数)识别重要领域的热点技术、关键技术和新兴技术。以合成生物学专利为例进行实证研究,结果显示,该分析框架有助于把握技术融合的整体发展态势,能够有效识别研发热点和关键技术,分析演化轨迹并预测发展趋势。
Based on patent co-classification information,the analysis framework of technology convergence was constructed from the overall and local perspectives.At the overall level,the distribution and annual change of technology fields convergence were analyzed,and the degree of convergence among technology fields was analyzed by using technology fields co-occurrence.At the local level,bibliometric indicators(co-occurrence frequency,betweeness centrality and burstness)were used to identify hot technologies,key technologies and emerging technologies in important fields.An empirical study was conducted on the synthetic biology.The proposed analysis framework was helpful to grasp the overall development trend of fusion technology,and could effectively identify hot spots and key technologies,analyze the evolution trajectory and predict the development trend.
