摘要
城市全域数字化转型是推动城市高质量发展的重要引擎。以长三角地区41个城市作为网络节点,运用基于制度距离修正的引力模型构建城市全域数字化转型空间关联网络,通过复杂网络分析方法和面板回归模型,对城市全域数字化转型的网络结构特征及其效应进行分析。研究表明:(1)2022—2024年间,长三角地区城市间数字化转型联系愈发紧密,网络结构呈现网络密度、网络关联度和网络效率上升,网络等级度下降的趋势;(2)网络节点特征存在明显异质性,不同城市在全域数字化转型进程中,资源汇聚、控制和交流能力存在差异,块模型分析进一步将城市划分为四大功能板块;(3)城市全域数字化转型空间关联的网络密度、网络关联度和网络效率,能够显著提升区域整体数字化转型水平及其空间均衡性,城市在网络中的中心性地位对个体全域数字化转型水平具有显著的促进作用。
Urban all-dimensional digital transformation is an important engine for promoting high-quality urban development.Taking 41 cities in the Yangtze River Delta as network nodes,this study constructs a spatial association network for urban all-dimensional digital transformation with a gravity model revised by institutional distance.Through complex network analysis and panel regression models,this study analyzes the network structure characteristics and their effects of urban all-dimensional digital transformation.The research shows that:(1)During 2022-2024,the connections of digital transformation among cities in the Yangtze River Delta region have become increasingly close.The network structure shows trends of increasing network density,connectivity,and efficiency,while decreasing hierarchy.(2)The analysis of network node characteristics indicates that,during the process of urban all-dimensional digital transformation,different cities vary in their capabilities of resource aggregation,control,and communication.The Block-model analysis further divides the cities into four functional blocks.(3)The network density,connectivity,and efficiency of the spatial association network of urban all-dimensional digital transformation can significantly enhance the overall regional digital transformation level and its spatial equilibrium.The centrality position of a city in the network has a significant positive effect on its own all-dimensional digital transformation level.
