国家自然科学基金是我国支持基础研究的最主要的渠道之一,获得国家自然科学基金项目的能力已经成为衡量地区和科研机构基础研究力量的一项重要指标。本文基于2001—2010年10年间的国家自然科学基金立项信息,分析了我国基础研究力量的变化趋势。省、自治区、直辖市层面呈现均衡化发展趋势,而机构层面两极分化的趋势有可能加剧。 The National Natural Science Foundation of China is one of the most important channels for supporting basic research in our country. The ability to acquire projects of the National Natural Science Fund has become an important indicator of the basic research strength of regions and scientific research institutions. Based on the project information of National Natural Science Foundation of China during the decade of 2001-2010, this paper analyzes the trend of change of basic research forces in China. The provinces, autonomous regions and municipalities directly under the Central Government are expected to exhibit a balanced development trend, while the polarization of the institutions may be aggravated.
