摘要
以中国东北地区城市人口数据和城市人口迁移的引力模型为基础,建立了城市网络,并利用复杂网络的理论和研究成果,分析了城市人口迁移的网络特征,发现城市网络具有典型复杂网络的无尺度特性,人口与城市的关系如同Internet的网络流量与节点之间的关系,城市人口的迁移具有偏好依附特性,给出了偏好依附的模型.同时对东北地区城市网络中节点的度分布进行了研究,依据各城市在网络的节点度情况,预测了东北地区未来发展的情况.
Based on the census date of Northeast China and the gravitation model of urban population migration, an urban network was established and the network characteristics of urban population migration were analyzed according to the complex network theory and existing research achievements. The results showed that the urban network is typically scale-free, and the relation between the population and the city where they live in is just like that between the network throughput and the nodes. The migration of urban population has a tendency to preference. So, a preference model was developed. Furthermore, the degree distribution of nodes of the urban network in Northeast China was also discussed. In the light of the node degree of each and every city, the future development centers in Northeast China is predicted.
