International collaboration have played important role in academic activities, while more and more researchers endeavor to participate in joint research or exchange with partners aboard. Focused on projects of Major International (Regional) Joint Research Program of NSFC, characteristic of scientific collaboration was investigated by mapping the funded projects from the aspects of topic, affiliation and cooperative country (region) respectively. Moreover, it is demonstrated that issues related to nano, gene and ecological environment have become the hot topics in the joint research in China, and projects with issues of big science have been preferentially funded under the program's guide posted every year. Moreover, most granted projects were undertaken by the minority of affiliations with the leading research capability, the same to partners aboard. The aggregation effect has been greatly enhanced with the bilateral or multilateral agreement signed with scientific organizations abroad, so has the competitive mechanism of scientific resources allocation.
