Patterns and Influencing Factors of Urban Network Correlation in the Yellow River Basin:Based on the Perspective of Digital Economy Enterprise Investment
Based on the investment data of digital economy listed companies in 2010,2015 and 2020 and by using the social network analysis method,this study analyzes the spatio-temporal evolution characteristics of the Yellow River Basin urban network based on digital economy enterprise investment and reveals the influencing factors by using the QAP model.It is found that firstly,Xi'an,Qingdao and Jinan have always been the main investment cities,and the digital manufacturing industry is the main direction for digital economy enterprises to invest in;secondly,the Yellow River Basin urban network structure shows that the overall network accessibility is high and stable while the digital economy connections among the cities are becoming increasingly close;the individual networks exhibit both neighbor diffusion pattern and jump diffusion pattern while the high administrative level's directionality leads to a significant"Matthew effect";the local networks exhibit geographical-spatial proximity characteristics while the subgroup distribution transitions from the central and western regions to the eastern regions,breaking through the"island style"development and forming a"belt style"pattern;and thirdly,traffic density,innovation capability,geographical distance and administrative relationship are the main factors driving the development and layout of the Yellow River Basin digital industries,but there exist industry heterogeneity characteristics.Traditional location factors have a greater impact on digital manufacturing industry,which can easily lead to"location locking"and"industry locking",while digital service industry tends to layout in high-level administrative gathering areas.
