中文摘要：

生物技术高度依赖于创新网络，成功的生物创新需要整合产学研的知识、人才、资金和市场等各种资源。利用中国知网论文数据，结合文献计量和社会网络分析方法，分别从作者、机构和区域等多个层面和角度对我国生物技术的合作特征展开深入研究。研究显示，96％以上的生物论文为合作产物，且以来自同一机构的群作者和多作者合作为主，当发生机构间合作时更倾向于选择区域外机构作为合作对象。

英文摘要：

Successful biotechnology highly relies on innovation network, which can integrate knowledge, human, capital and market from acade- mia and industry. Using CNKI paper data and methods from bibliometrics and social network analysis, it aims to study the collaboration pattern of Chinese biotechnology at author, affiliation and region level, and especially the roles of regions in the collaboration network. Results show that more than 96 ~ papers include author collaborations and the most common pattern is collaboration within no less than three authors from one affili- ation. When affiliation collaborations happen, they prefer to choose partners from other regions.
