交通网络对云南省经济联系驱动作用的空间异质性分析

Spatial Heterogeneity of the Driving Effect of Transportation Networks on Economic Connections in Yunnan Province

摘要: 通过引力模型，测算出云南省城市间经济联系强度，从而构建全省经济联系网络，并以城市经济联系势能为因变量，公路网密度为自变量，运用最小二乘法和地理加权回归模型探索交通网络对经济联系驱动作用的空间异质性。研究表明：云南省经济联系层级现象显著，高强度的联系关系缺乏，东强西弱的特征明显；公路网对经济联系具有显著的驱动作用，且这种驱动作用存在空间异质性。

Abstract: Through the gravity model, the intensity of economic connections between cities in Yunnan Prov-ince is measured, so as to construct the province’s economic connection network. With the urban economic connection potential as the dependent variable and the highway network density as the independent variable, the least squares method and geographically weighted regression model are used to explore the driving force of traffic network on economic linkage spatial heterogeneity of action. Research shows that Yunnan Province has significant levels of economic ties, lack of high-strength ties, and obvious characteristics of strong east and weak west; the highway network has a significant driving effect on economic ties, and this driving effect is spatially heterogeneous.
