Abstract:

With the continuous improvement of transportation infrastructure and communication technology, the degree of interaction between cities has significantly increased. Based on panel data of 26 prefecture-level cities in the Yangtze River Delta, this paper investigates the characteristics of the multi-scale urban network and the impact of urban network on high-quality development from the perspective of corporate headquarters-branch connections. The results are as follows: (1)Both the overall network characteristics and the node network connections indicate that the urban network at different scales in the Yangtze River Delta exhibits a trend of network development. (2) Urban network connections in the Yangtze River Delta exhibit significant hierarchical characteristics. As the network hierarchy increases, the number of connections decreases, and the levels of participating cities increase, with less constraint imposed by distance and administrative levels.(3) Cities within the Yangtze River Delta can significantly advance high-quality development by integrating into an urban network of different scales, and the impact of urban network connections on high-quality development demonstrates both scale heterogeneity and size heterogeneity. (4) Cities within the Yangtze River Delta primarily achieve high-quality development through three transmission mechanisms: the economic effect, social effect, and innovation effect of the urban network.

摘要：

随着交通基础设施和通信技术的不断完善，城市间相互作用程度显著提高。本文基于长三角26个地级市面板数据，运用社会网络分析方法、随机效应模型和固定效应模型等方法，研究了企业总部-分支联系视角下的长三角多尺度城市网络特征及其对高质量发展的影响。研究结果显示：无论是从整体网络特征还是从节点的网络联系来看，基于企业内部组织的不同尺度城市网络均呈现出网络化的发展趋势；长三角群内尺度网络联系和群外尺度网络联系均具有明显的层级性，网络层级越高，联系对数量则越少且参与的城市等级越高，同时受到距离与行政隶属约束越弱；长三角内部城市能够通过嵌入不同尺度的城市网络，显著地提升其城市高质量发展，同时城市网络联系对城市高质量发展的影响存在尺度异质性和规模异质性；长三角内部城市主要通过城市网络的经济效应、社会效应以及创新效应三种传导机制实现城市高质量发展。
