探索经济空间关联特征演化及其网络效应对于优化粤港澳大湾区经济空间合作格局具有重要的理论意义.该文综合运用修正引力模型、社会网络分析法和OLS回归模型分析粤港澳大湾区经济空间关联特征演变及网络效应,结果表明:1)粤港澳大湾区经济联系强度不断提升,空间上四核驱动,边缘辐射渐趋稳定.经济联系空间势能不断跃升,网络密度和网络关系数均呈波动上升态势,网络等级度在起伏变化中轻微增长,网络效率呈先降后升的“V”形结构.2)点度中心度稳步提升,网络中心性整体不断增强,空间结构由多点集聚逐步演变至两极对峙,接近中心度的空间非均衡性强且变化悬殊,中间中心度大幅跃升,深圳在经济联系网络中的控制力遥遥领先.3)网络密度和网络等级度的提高以及网络效率的降低能有效提升粤港澳大湾区的经济联系强度,而点度中心度、中间中心度和接近中心度均能推动大湾区经济联系的增强.
