数字经济发展对黄河流域城市能级影响机制研究OA

In order to quantify the impact of digital economy on urban function level,a multi-dimensional evaluation framework was established to assess both the digital economy and the urban function level.By applying the entropy weighting approach,the study quantitatively analyzed the digital economy and urban function level across the Yellow River Basin from 2012 to 2022.The fixed effects and mediation models were employed to explore the mechanism through which the digital economy influenced the urban function level in the Yellow River Basin.Additionally,the threshold effect model was employed to explore how the digital economy influences urban function level.The findings revealed that:1)Both digital economy de-velopment and urban function level experienced a consistent upward trajectory over time in the Yellow River Basin.Moreover,the advancement of the digital economy contributed positively to the enhancement of urban function level.2)The digital economy could indirectly promote the improvement of urban func-tion level by enhancing the per capita scientific research funding level in cities.3)The impact of the dig-ital economy on urban function level was nonlinear.
