京津冀城市间人口流动网络研究——基于腾讯位置大数据分析

Research on the Population Mobile Network in Beijing-Tianjin-Hebei:Based on Tencent location Big Data

基于腾讯位置大数据,运用GIS和复杂网络分析等方法,构建京津冀区域城市间的人口流动网络模型,从网络结构和空间格局两个方面测度京津冀区域城市间人口流动的复杂网络特征。结果表明:(1)京津冀城市间人口流动网络符合"小世界"网络特征,具有较高的连通性和运行效率,并且所有城市节点的人口流入和人口流出均呈显著正相关,说明目前京津冀人口可以跨越行政界限自由流动,且保持相对平衡,京津冀协同战略发展已经取得了实质性效果。(2)京津冀城市间人口流动网络具有明显层次性,呈现"北疏南密"流动分布态势和"一大三小"多中心网络空间格局,并非传统认知上"京津双核心"空间格局。研究结果对于引导人口合理流动,促进京津冀区域人口、资源与经济社会的协调发展具有参考价值。

Based on Tencent location big data,GIS and complex network analysis methods were used to construct a population mobility network model among Beijing,Tianjin,and Hebei provinces,and the complex network characteristics of inter-city population mobility in Beijing,Tianjin,and Hebei were measured in terms of network structure and spatial structure.The results show that:(1)At present,the Beijing-Tianjin-Hebei inter-city population mobility network is in line with the“small-world”network characteristics,with high connectivity and operational efficiency,and there is a significant positive correlation between population inflow and outflow of population in all urban nodes.It shows that the current population of Beijing,Tianjin and Hebei can move freely across administrative boundaries and maintain a relatively balanced balance.The development of the Beijing-Tianjin-Hebei coordinated strategy has achieved substantial results.(2)The inter-city population mobility network of Beijing,Tianjin,and Hebei has a clear hierarchy,showing the“Northern-southern-secret”flow distribution pattern and the“one big three small”multi-centered cyberspace pattern,which is not traditionally known as“Beijing-Tianjin Core"spatial pattern.The research results have a reference value for guiding the reasonable flow of population and promoting the coordinated development of population,resources and economic society in the Beijing-Tianjin-Hebei region.
