摘要
本文通过测算2006-2021年我国省际数字经济核心产业增加值,利用网络分析方法揭示我国数字经济空间关联网络结构特征,并基于指数随机图模型实证考察数字经济空间关联网络形成机制.研究发现,我国数字经济的空间关联网络呈现典型的"中心一边缘"结构,东部省份对中、西部省份产生虹吸效应,我国数字经济形成了以上海为代表的集聚式发展模式和以广东为代表的内生式发展模式.然而,随着数字资源不断向部分省份聚集,各地区难以自发形成空间关联关系,因此应提高数字经济规模,加大数字基础设施建设和数字人才储备,鼓励技术创新和共享,扩大居民消费,以促进我国数字经济空间关联网络的形成,更好发挥数字经济的空间溢出效应.
Abstract
By measuring the added value of China's inter-provincial digital economy core industries from 2006 to 2021,this paper uses the network analysis method to reveal the structural characteristics of China's digital economy spatial correlation network and further investigates the formation mechanism of the digital economy spatial correlation network based on the exponential random graph model.The study finds that China's digital economy presents a spatial correlation network structure with a typical"center-periphery",and the eastern provinces have a siphon effect on central and western provinces.There is an agglomeration development model represented by Shanghai and an endogenous development model represented by Guangdong in China's digital economy.As digital economic resources converge to a few advantageous provinces,it is no longer feasible to form spatial correlation spontaneously.Increasing the scale of the digital economy,increasing the construction of digital infrastructure and talent pools,encouraging technological innovation and sharing,and expanding residents'consumption can significantly enhance the establishment of spatial correlation network in China's digital economy,and thereby leverage the spatial spillover effect of digital economy.
