长三角数字创新网络空间结构演化及机制差异的多尺度分析

Spatial Structure Evolution and Mechanism Differences of Digital Innovation Networks in the Yangtze River Delta:from a Multi-Scale Perspective

本文以长三角地区为研究对象,从“省域-市域-区县域”空间尺度入手,通过空间相关性分析、引力模型、社会网络分析等方法剖析长三角不同尺度数字创新分布格局和网络结构特征,并利用QAP方法对不同尺度空间网络结构差异机制进行分析。研究发现:长三角数字创新活动呈现明显的空间分异格局;城市群与都市圈正在成为数字创新活动及网络的主要空间表现形式;长三角数字创新网络的形成与发展是多种社会经济因素相互作用的结果。基于此,提出长三角数字创新网络构建的政策建议,各地应当抓住长三角一体化战略,通过引进数字人才、改善公共交通与数字基础设施等措施促进数字化转型。

This paper takes the Yangtze River Delta region as the research object,starting from the spatial scale of“province-city-county”,and analyzes the digital innovation distribution pattern and network structure characteristics of the Yangtze River Delta at different scales by using spatial correlation analysis,gravity force model,social network analysis,and uses QAP method to analyze the mechanism of difference of spatial network structure at different scales.The study found that the digital innovation activities presented obvious spatial differentiation patterns;city clusters and metropolitan areas are becoming the main spatial manifestations of digital innovation activities and networks;the formation and development of digital innovation networks in the Yangtze River Delta is the result of the interaction of various socio-economic factors.Based on this,policy recommendations for the construction of digital innovation networks are proposed,Localities should seize the Yangtze River Delta integration strategy to promote digital transformation through measures such as introducing digital talents and improving public transportation and digital infrastructure.
