不同领域技术涵盖性的测度及启示

Measuring Technology Coverage in Different Domains and Its Inspirations

测度并比较不同领域的技术涵盖性,将有助于我们掌握不同领域的发明创造规律,提高专利技术研发效率。选取《德温特创新索引》数据库中符合设定条件的专利数据,采用技术共类分析方法,通过4项指标探测不同领域的技术涵盖性。分析结果表明,高分子聚合物与塑料领域的技术涵盖性最广泛,计算与控制技术领域、耐火材料-陶瓷-水泥和有机物电镀技术领域的技术涵盖性比较广泛。

Measuring and comparing the technology coverage of different domains have great significance in grasping the law of inventions and.improving R＆D efficiency. Choosing the given patent dataset in Derwent Innovations Index, employing technology co-classification analysis, the issue of measuring technology coverage is explored by using four indicators. The results show that the area of polymers and plastics has the widest scope in terms of technology coverage; and the areas of computing and controls, refractories-ceramics-cement and organics electroplating have the comparatively wide scope of technology coverage.
