By applying bibliometric and social network methods, this study provided the collaboration network of countries and fields. The main results were as follow: the number of article increased faster comparing with the stable growth in average annual of IRC degree; the articles collaborated with SAC are 80 % more than all IRC’s; as to the fields, collaboration in Social science is at disadvantage, while the largest field is physics and the fastest field is molecular biology and genetics; mathematics, physics, multidisciplinary and space science had more in fluencies than others in corresponding respective journals; as to the network, USA, as the largest and most important partner, had 30 % IRC articles, and collaborated with China in all 22 ESI fields.
