越来越多的研究使用社会网络分析来研究犯罪网络。这项研究的绝大多数都是在一个时间点上考察网络。虽然有一些理论方法对犯罪网络如何发展和壮大进行了假设，但很少有关于犯罪网络随着时间的推移而增长的实证研究。该项目记录了贩毒网络的增长。目的是审查和描述犯罪网络在不同时间的结构和功能变化。我们发现网络的密度随着时间的推移保持一定的稳定，尽管网络在测量的最终时间点变得更加分散。单个节点的中心性得分随时间推移而发生显著变化。随着时间的推移，个人改变了所扮演的角色，这与网络不断变化的需求和重点是一致的。总的来说，我们的研究结果支持网络的灵活性和适应性。
There is a growing body of research using social network analysis to study criminal networks. The great majority of this research examines networks at a single time point. Although there are theoretical approaches which hypothesise on how criminal networks develop and grow, little empirical research has been conducted on the growth of criminal networks over time. This project documents the growth of a drug trafficking network. The aims were to examine and describe structural and functional changes in a criminal network across time. We found that the density of the network remained somewhat stable over time, although the network became more decentralised at the final time point measured. Centrality scores for individual nodes showed significant changes over time. Individuals changed the roles performed across time, consistent with the changing needs and focus of the network. Overall, our results support the characterisation of networks as flexible and adaptive.
