摘要: 结合跨城手机信令和人口数据，区分高频与低频城际出行，运用社会网络分析法比较不同频率关联网络的空间分布特征及上海市的空间分布异质性，通过基于重力模型的泊松回归估算解析分布模式和形成机制，并分析不同频度、不同空间层面的关联网络嵌套对邻沪地区一体化发展的影响。研究发现，高、低频关联网络嵌套重叠部分的边界效应和低频关联的蔓延加飞地特征，城际与市域关联网络叠合形成多层嵌套式空间结构；城际关联符合泊松分布模式；高、低频重叠区块具备一体化发展物质空间条件，上海市新城具有衔接作用，以期为区域一体化发展政策提供依据。
Abstract: This study aims to contrast the spatial distribution of the high-frequency and low-frequency city networks using mobile signaling and census data. The mechanism is explored based on the Poisson regression. The impact of the city network on regional integration is revealed. The results show that both high and low frequency city networks are densely distributed around the administrative boundaries. Secondly, the trips conform to a Poisson distribution. The high-frequency trips are very sensitive to distance, restraining the spatial scope, whereas the low-frequency trips are supported by regional transportation facilities. Lastly, the overlaid high-frequency and low-frequency networks lay the foundation for integration development. The conclusions provide implications for the integration policies such as the Yangtze Delta Region Demonstration Area.
