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.

Key words

factor flow / distance-decay effect / improved gravitational model / QAP / Chengdu-Chongqing Economic Circle
