摘　　要：使用复杂网络工具构建并分析了2006年我国有机化学工业原料供应链网络,对其结构特征进行了识别和判断。对于包含企业和化学品两类节点的有机化学工业原材料供应链网络研究结果表明,网络整体连通性好,度分布部分符合幂律分布的形式,网络结构非均匀性较强。网络的平均路径长度远小于同等规模的随机网络,说明有机化学工业网络的信息传递能力很强。The supply chain network of Chinese organic chemical industry in 2006 was established and analyzed based on complex network tools. The analysis of the enterprise-product two-mode network showed that the supply chain network had excellent connectivity. With the increase of node degree, the frequency reduced gradually, and the tail parts of the distribution followed power laws. The network structure is of strong heterogeneity. The average path length between any two nodes of the supply chain network was much smaller than that of random networks with the same scale, showing strong capacity of information transmission in the network.
