摘要
本文基于长三角数字经济企业股权关联数据,以地级市市区和县市为研究单元构建有向加权的数字经济产业投资网络.运用度中心性和中心势、社区分析等网络分析方法研究2010-2020年长三角数字经济产业网络演变特征,总结核心扩展、节点扩展、边缘扩展等空间扩展模式以及网络演化的起步、发展、成熟、完善四个阶段.研究发现:2010-2020年,长三角数字经济网络的极化过程逐渐减缓,网络逐渐趋于稳定和集中,呈现出"钻石+放射状"的空间结构,且其网络社区与行政边界耦合程度较高.长三角数字经济网络先后经历了以核心扩展为主和核心扩展与节点扩展并重的阶段,呈现出明显的等级扩散特征.
Abstract
The development of information technology has profoundly changed human production and life-style as well as socio-economic organizational models,bringing about a drastic transformation of urban and regional space.Based on the equity correlation data of digital economy enterprises in the Yangtze River Delta,this paper constructed a weighted digital economy industrial investment network with prefecture-level cities and counties as the study units.This paper studied the evolution characteristics of the network of the digital economy of the Yangtze River Delta from 2010 to 2020,and summarized three spatial expansion modes of core expansion,node expansion and edge expansion.The research findings are as follows:(1)From 2010 to 2020,the polarization process of the Yangtze River Delta digital economy network gradually slowed down,and the network gradually became stable and centralized.(2)The core region of the Yangtze River Delta digital economy network basically covered Jiangsu,Zhejiang and Shanghai.(3)The Yangtze River Delta digital economy network presents a"diamond+radial"spatial structure,and the triangle formed by Shanghai,Hangzhou and Ningbo occupies the center of gravity of the entire structure.(4)The overall net-work of the Yangtze River Delta digital economy has experienced a stage of focusing on core expansion and paying equal attention to core expansion and node expansion.
