黄河流域数字经济发展水平时空特征与影响因素OACHSSCDCSTPCD

The digital economy is the focus of China's future long-term development,and studying the digital economy of the Yellow River Basin can provide new opportunities for its high-quality development.Based on the connotation of digital economy,this paper took the Yellow River Basin as a case study area,constructed a digital economy development level evaluation index system,and used the Kernel density estimation,Moran's I and GTWR model to quantitatively measure the pattern of spatio-temporal divergence and the influencing factors of the digital economy development level of the Yellow River Basin from 2011 to 2019.The results showed that:①The development level of the digital economy in the three major regions of the Yellow River Basin has been increasing,and the development differences have continued to expand,with a significant step-increasing effect between the upstream,midstream,and downstream regions.②There was the phenomenon of"center-periphery"in the development of digital economy in the upper reaches of the Yellow River,and the middle reaches of the Yellow River showed the characteristics of hierarchical differentiation,and there was a tendency to reduce the development gap in cities in the lower reaches of the Yellow River.③The spatial correlation of the digital e-conomy development in the Yellow River Basin was significant and presented the local polarization pattern of HH agglomeration and LL agglomeration.④The ecological environment,industrial structure,informatization level,government intervention,and human capital level in the Yellow River Basin all had an impact on the development of the digital economy in the Yellow River Basin,and there were signifi-cant regional differences in each of the influencing factors.
