中国数字经济空间关联网络及其影响因素分析

Analysis on the Spatial Correlation Network and Its Influencing Factors of Digital Economy in China

基于2013年和2020年29个省的数据,用因子模型测算各省数字经济发展水平,在此基础上使用修正引力模型构建数字经济空间关联网络,并深入分析此网络特征。结果表明:中国数字经济发展水平存在差异,东部地区高于中西部地区;中国数字经济空间关联网络密度不断增大;北京、山东、江苏一直是网络的重要输出省份,近年来西部地区在网络中的作用越来越明显;地理位置相邻、贸易开放度和产业结构对网络的形成有显著影响。

Based on the data of 29 provinces in 2013 and 2020,the development level of the digital economy in each province was evaluated using the factor model.Based on this,the spatial correlation network of the digital economy was constructed by using modified gravity model,and the characteristics of this network were analyzed.The results show that there are differences in the development level of digital economy in China.The development level of provinces in eastern region are relatively higher.The network density is increasing.Beijing,Shandong,and Jiangsu have always been major outputting provinces of the network,and the role of the western region in the network becomes more and more important in recent years.Geographical proximity,trade openness,and industrial structure have significant impacts on the formation of network.
