我国中药核心专利技术区域分布研究

利用情报学领域的布拉德福定律对约3000个与中药相关的IPC分类技术进行了统计分析,确定了1988-2009年我国18类中药领域的核心专利技术。以"企业专利密度"考查我国中药核心专利技术的分布规律,可见作为第一阶梯的北京、天津、山东、贵州以及江西的中药核心专利技术占有明显的优势,企业核心专利密度在11.38-7.83之间;其次是作为第二阶梯的我国中部和西南地区包括四川、浙江、江苏和上海在内的11个省、自治区和直辖市,企业核心专利密度在4.56-3.76之间;再次是作为第三阶梯的包括山西、西藏、新疆、宁夏以及青海在内的我国西北、东北以及东南地区,企业核心专利密度在3.72-1.53之间。虽然第二、三阶梯企业专利密度较小,但却有其不能取代的特色。

The Regional Distribution Study of Core Patented Technologies of Chinese Medicine

Based on the analysis of Bradford's law for 3,000 related to the IPC classification technology, 18 core patented technologies in Chinese medicine field have been determined from1988 to 2009. In view of distribution regulation of corporate patent intensity, the core patented technology in our country has advantage and with a patent-density core between 11.38 and 7.83 as the first step of Beijing, Tianjin, Shandong, Guizhou and Jiangxi. Then, the second step is followed by the central and southwest China, including Sichuan, Zhejiang, Jiangsu and Shanghai, including 11 provinces, autonomous regions and municipalities, with the corporate patent density between 4.56 and 3.76. Furthermore, the third step is also followed by the northwest, northeast and southeast regions including Shanxi, Tibet, Xinjiang, Ningxia and Qinghai with the core density between 3.72 and 1.53. Although the second, third classification are less at enterprise patent density, the characteristics can not be replaced.
