产业协同集聚是产业集聚的高级阶段,其与城市群交通网络的演化密切相关,关于交通网络结构与产业协同集聚关系的讨论仍存争议.针对关中平原城市群的高速公路网络进行建模分析,采用凝聚子群的重叠性作为网络结构特征的指标,并应用广义线性模型探讨两者间的关系.结果表明,城市群交通网络中的凝聚子群重叠性对产业协同集聚具有负面影响.这一结构特征通过促进资源的反向流动,可能降低某些区域的产业协同集聚水平.作为一种综合性指标,凝聚子群重叠性能稳定评估交通网络与产业协同集聚之间的联系,对于优化城市群交通网络规划和区域产业协同集聚具有重要的理论和实际意义.
Effects of Urban Agglomeration Transport Network Cohesive Subgroup Overlap on Industrial Co-agglomeration
Industrial co-agglomeration represents an advanced stage of industrial clustering and is closely linked with the evolution of urban agglomeration transportation networks.Despite ongoing debates regarding the relationship between the structure of transportation networks and industrial co-agglomeration,a modeling analysis was conducted in this study on the expressway network of the Guanzhong Plain urban agglomeration.The overlap of cohesive subgroups as an indicator of network structural characteristics was utilized,a generalized linear model was employed,and the relationship between the two was explored.The results reveal that the overlap of cohesive subgroups in the urban agglomeration transportation network negatively affects industrial co-agglomeration.By promoting the reverse flow of resources,this structural feature may reduce the level of industrial co-agglomeration in certain areas.As a comprehensive indicator,the overlap of cohesive subgroups provides a stable assessment of the link between the transportation network and industrial co-agglomeration and therefore has significant theoretical and practical importance for optimizing the planning of urban agglomeration transportation networks and regional industrial co-agglomeration.
