摘要

集成多元地理流大数据构建成渝地区双城经济圈人流、物流、信息流、资金流和技术流网络，利用改进重力模型测算多维要素流动距离衰减系数，构建城际要素流动距离衰减度指标反映城际要素克服距离衰减的流通能力，并借助QAP回归探讨城际多维要素流动距离衰减度的影响机制。结果表明：①人流、资金流、技术流、物流呈现较显著的距离衰减，总体衰减效应强度人流>资金流>技术流>物流；而信息流距离衰减不显著。②人流、资金流自由流动程度较高，而物流、信息流、技术流配置体现为向枢纽城市倾斜。③人流、资金流受行政分割、城乡二元体制、产业同构的限制，受城市体系层级结构的促进；一体化政策可促进人流、信息流；物流、技术流则由等级化扩散主导。

Abstract

From the perspective of attribute-network relationships, this study integrates multivariate geographical flow big data and relevant socio-economic statistical data to construct networks of population flow, logistics, information flow, capital flow, and technology flow in the Chengdu-Chongqing Economic Circle. The following conclusions are drawn: 1) Distance decay effects exist in the flows of population, logistics, capital, and technology, with the overall strength of distance decay being population flow > capital flow > technology flow > logistics flow. 2) The intercity multidimensional factor flow distance-decay degree demonstrates dual characteristics of factor-type heterogeneity and geographical spatial heterogeneity. 3) Population flow and capital flow are primarily constrained by administrative segmentation, urban-rural dual systems, and industrial isomorphism.
