摘　　要： 利用复杂网络理论对国内外供应链管理研究领域的科研合作网络进行了对比研究。首先,进行了统计实证研究,证明国内和国际科研合作网络都是无标度网络;其次,对科研合作网络的各种性质进行了分析,发现在平均每位作者论文数、平均每篇论文合作人数和平均每位作者合作人数等指标上国内外网络基本相似,具有相同的学科特点。而在最大连通集团、社团结构和度相关性指标上国内外网络明显不同,说明国内外合作模式有较大差别。国内的合作群体相对分散,倾向于按地域或相同师承的合作,缺少强强联手,国内合作规模和合作程度与国际相比仍有相当差距。 This paper studies the author networks in su and internationally based on complex networks theory. First verifies the author networks are both scale-free networks. the author networks and concludes that the domestic and th pply chain management both domestically , it calculates the degree distributions and Second, it analyzes various properties of e international author network are similar in terms of the average number of paper per author, average number of co-authors per author and average number of co-authors per paper. The paper also puts forward that there are significant diffeences in the maximum components, community structure and degree correlations, which indicates different co-author patterns of the two different types of networks
