Abstract:引用城市流强度修正传统引力模型构建经济联系矩阵,运用社会网络分析方法对2008 2018年关中平原城市群经济联系网络结构演变特征及对经济增长的影响进行分析。结果表明: (1)城市群中心性水平较弱,经济网络处于极化发展期,区域发展不平衡问题突出。(2)西安影响 力不断增大,非核心城市影响力降低,在区域内形成灯影效应。(3)凝集子群内部的集聚程度由松散向紧密发展,城市三级凝聚子群与城市所在省级行政区划分由不耦合演变为全部耦合。(4)城市群平均核心度值水平较低且逐渐升高,核心区域由西安单核心演变为西安、咸阳双核心发展结 构。(5)城市的中心性、影响力及集聚性对城市经济增长的影响存在差异。
