摘　　要：数字经济是中国未来长效发展的重点,研究黄河流域数字经济能够为其高质量发展提供新机遇。基于数字经济内涵,构建数字经济发展水平评价指标体系,以黄河流域为案例研究区域,采用Kernel核密度估计、Moran′s I、GTWR模型定量测度2011—2019年黄河流域数字经济发展水平时空分异格局与影响因素。结果发现:①黄河流域三大地区数字经济发展水平不断提升,发展差异持续扩大,上中下游地区之间存在显著阶梯递增效应;②黄河上游数字经济发展存在“中心—外围”现象,中游地区呈现层级分化特征,下游地区地级市间发展差距有减小趋势;③黄河流域数字经济发展空间相关性显著,局部呈现HH集聚和LL集聚两极分化格局;④黄河流域生态环境、产业结构、信息化水平、政府干预程度及人力资本水平均对黄河流域的数字经济发展产生影响,且各影响因素存在显著的地区差异。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 economy 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 significant regional differences in each of the influencing factors.
