| 摘 要： | 专利情报和学术文献间既存在着共通性，同时也具有差异性。为了考察两者差别，采用情报方法中的共引分析法分别构建专利情报和学术文献的共引矩阵，进一步聚类成产业公司群和学术团体群；然后将其可视化，以直观的方式将两者进行对比。通过比较，观察到产业集群更为集中，而学术集群略为分散。同时也发现中国公司与国外公司在研究方面存在着较大差距。

| Abstract: | The consistency exists between the patent intelligence and academic information, so does the difference. The author produces the co citation matrices of patent intelligence and academic information separately by using the co citation analysis method to investigate the difference, and then identifies the industry clusters and academic clusters. Finally, the clusters are visualized and compared directly. The results indicate that industry clusters are more centralized, while academic clusters are decentralized slightly. And the research gap between the Chinese corporations and foreign corporations is also concluded. |
