长三角数字经济一体化高质量发展研究

Research on High-quality Development of Digital Economy Integration in the Yangtze River Delta

以江浙沪皖三省一市41个城市作为空间节点和研究对象,从辐射效应、外向联系度与辐射网络三个维度构建评价框架。研究结果表明长三角数字经济辐射效应与外向联系均发生城市分异,呈现出“两超多强”和“东强西弱”的城市格局。经济辐射网络形成了双内核、三中心、四节点,多外延的“钻石型”嵌套结构。总结而言,长三角数字经济已经具备了产业分工协作、资源协同的雏形,但整体尚处于“高质量一体化”初级阶段。

Taking 41 cities in three provinces and one city in Jiangsu, Zhejiang, Shanghai and Anhui as spatial nodes and research objects, an evaluation framework is constructed from three dimensions:radiation effect, outward connection degree and radiation network.The research results show that the digital economy of the cities in the Yangtze River Delta has differences in radiation effect and outward connection, showing a pattern of "two superpowers and many strong" and "east strong and weak in the west".The economic radiation network has formed a "diamond" nested structure with double cores, three centers, four nodes and multiple extensions.To sum up, the digital economy of the Yangtze River Delta has the prototype of industrial division of labor and resource coordination, but it is still in the initial stage of "high-quality integration".
