This paper studies the author networks in supply chain management both domestically and internationally based on complex networks theory. First, it calculates the degree distributions and verifies the author networks are both scale-free networks. Second, it analyzes various properties of the author networks and concludes that the domestic and the 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 differences in the maximum components, community structure and degree correlations, which indicates different co-author patterns of the two different types of networks
