摘　　要：为探究城市企业网络与信息网络的耦合联动效应,提出相关性-多重耦合网络-耦合联动效应评价(CMC)的综合研究框架,以成渝地区双城经济圈城市企业网络和信息网络耦合为例,在分析网络结构特征的基础上,进一步剖析企业网络与信息网络的耦合联动效应。研究表明:城市企业网络和信息网络存在复杂的非线性耦合关系;2011—2020年,成渝地区双城经济圈城市网络呈现典型的双核心模式,“马太效应”和“富人俱乐部”现象显著,耦合网络受企业网络的影响更大,在继承单一网络双核心特征的基础上,网络拓扑结构逐渐复杂化,相较于企业网络,耦合网络的“马太效应”显著性略低;2011—2020年,节点耦合联动多为中低水平,链接耦合联动多为中高水平且呈现减弱趋势,核心链接优势减弱;2020年受新冠疫情影响,城市综合能力提升不明显。Cities function as complex systems where subsystems interact to form higher-level urban complexes characterized by intricate nonlinear coupling relationships among various networks.Although a substantial amount of research on urban networks from the perspective of single-factor flow exists both domestically and internationally,such studies have limitations,as they do not fully capture the multifaceted nature of urban systems.Research on multi-city networks in China primarily examines the structural characteristics and dynamic mechanisms of networks with distinct attributes.While international studies have explored interactions and coupling effects among subsystems within complex systems,focusing on aspects like network robustness and cascading failures,relevant studies on urban networks remain relatively limited.This study proposes a comprehensive research framework called Correlation-Multiplex Coupling Networks-Coupling Linkage Effect Evaluation(CMC).Focusing on the coupling of enterprise and information networks in the Chengdu-Chongqing twin-city economic circle,this study further analyzes the coupling linkage effect between these networks.The results indicate that:First,there exists a complex nonlinear coupling relationship between information and enterprise networks,with a correlation coefficient exceeding 0.625 and different degrees of interactive coupling between nodes;second,from 2011 to 2020,there were notable differences in the core-edge structures of the three networks within the twin-city economic circle.Interactions between cities in core areas were more frequent than those in peripheral areas,displaying a prominent"rich man clubs"phenomenon and preferential links.The hierarchical structure and"Matthew effect"of the urban network were evident.The enterprise network evolved from a dual-core,single-strong link structure to a dual-core,multiple-strong-link structure,achieving a more balanced network over time.The information network transitioned from a single-centered structure around Chengdu to a weaker
