由于科学的综合性和复杂性,科研合作越来越广泛。本文以2008-2013年国家自然科学奖的获奖项目为研究对象,分析研究者合作状况,并将机构的合作形成复杂网络,从合作簇、合作强度、加权合作强度以及最大合作簇方面对其机构合作分析。结果表明,我国自然科学领域的研究需要多个研究者共同合作完成；机构合作方面,机构内合作较多,跨机构间合作相对较少。

Because of the synthesis and complexity of science, the research collaboration is widespread. The paper analyzed research collaboration of science domain in China based on national natural science award between 2008 and 2013. These were researched in the researchers’ collaboration and collaboration cluster, collaboration intensity, weighted collaboration intensity, and the maximum collaboration cluster of institution collaboration network using complex network. The results show that the researches of our country natural science require multiple researchers together to complete, and the inner collaboration of institution is more than the outsider.
