摘要：
在分析数字经济对黄河流域经济高质量发展的推动作用、边际效应递增的非线性影响以及空间效应的基础上,运用2011-2019年黄河流域57个地级市的面板数据,构建衡量经济高质量发展以及数字经济的指标体系,并运用固定效应模型、面板门槛模型和空间计量模型,实证分析数字经济对黄河流域经济高质量发展的影响.研究结果表明:数字经济能显著提高黄河流域经济高质量发展水平,并且这种推动作用存在“边际效应”非线性递增的趋势.空间计量实证结果表明数字经济可以显著提高本地区经济发展质量,但邻近地区数字经济发展会对本地区高质量发展产生负向影响.拓展了数字经济对黄河流域高质量发展影响的研究,对推动黄河流域实现经济高质量发展具有一定的借鉴意义.
Based on the analysis of the role of digital economy in promoting high-quality economic development in the Yellow River Basin,the nonlinear impact of increasing marginal effects,and spatial effects,this paper uses panel data from 57 prefecture-level cities in the Yellow River Basin from 2011 to 2019 to construct a high-quality economy.This paper constructs the index system of the high-quality economic development and the digital economy,and empirically analyzes the impact of digital economy on the high-quality economic development of the Yellow River Basin by using fixed effect model,panel threshold model and spatial econometric model.The research results show that the digital economy can significantly improve the high-quality economic development level of the Yellow River Basin,and this driving effect has a non-linear increasing trend ofmarginal effects.The empirical results of spatial measurement show that the digital economy can significantly improve the quality of economic development in the region,but the development of the digital economy in nearby regions will have a negative impact on the high-quality development of the region.This article expands the research on the influence of digital economy on the high-quality development of the Yellow River Basin,which is referential to promoting the high-quality economic development of the Yellow River Basin.
