中文摘要：

国家自然科学基金是我国支持基础研究的最主要渠道之一，获得国家自然科学基金资助的能力可以比较直观地反映出一个机构的基础科学研究能力及其水平。基于对19982012年15年间的国家自然科学基金立项信息的深入计算分析，本文对我国国家创新体系中两支非常重要的研究力量——中国科学院与中国九校联盟的基础研究能力进行了多维度的对比分析。研究结果表明，两者在自然科学领域中的整体基础研究能力比较接近，但在具体学科层面的研究优势差异较大，并有着较强的互补性；此外，中国科学院在争取承担国家重大重点任务方面具有一定优势，而C9联盟则在人才培育培养方面具有一定优势。

英文摘要：

The National Natural Science Funds （NNSF） is one of the most important channels through which China＇s basic research works are supported. The competitiveness on NNSF has become a very impor- tant measure of the scientific research abilities and levels of research institutions. Based on the NNSF pro- ject information during 1998--2012, this paper carried out a comprehensive comparative analysis between CAS and China＇s C9 League, which are two of the most important research teams in China＇s national inno- vation system, on their research abilities in the fields of basic research. The results show that, in the fields of natural sciences, CAS and C9＇s whole research abilities are very close. But in different fields, they often vary greatly, and have strong complementarity. In addition, CAS has more advantages in the aspect of un- dertaking national maior research projects, while C9 has certain advantages in the aspect of talent fostering.
