摘　　要：数字经济通过技术创新推动经济社会能源生产率变革,逐渐成为提升黄河流域高质量发展的新动力、新引擎.基于此,构建数字经济发展、能源生产率影响高质量发展的理论模型,并以黄河流域2013-2019年的省级面板数据为样本,通过面板计量模型、中介效应模型以及门槛效应模型等实证模型考察数字经济发展对黄河流域高质量发展的影响.研究显示,数字经济发展具有推动黄河流域高质量发展和提高能源生产率的双重效应;能源生产率在数字经济发展推动黄河流域高质量发展的过程中具有显著的渠道效应;数字经济发展对黄河流域高质量发展的影响存在“边际效应”非线性递增的特点,且在区域位置、人口规模等方面具有异质特征.Through technological innovation,the digital economy has promoted the transformation of energy productivity and gradually becomes a new driving force and engine for improving the high-quality development of the Yellow River Basin.Based on this,this paper builds a theoretical model of the impact of digital economy development and energy productivity on high-quality development.Taking the provincial panel data of the Yellow River Basin from 2013 to 2019 as samples,this paper examines the impact of digital economy development on high-quality development of the Yellow River Basin through empirical models such as panel econometric model,intermediary effect model and threshold effect model.The results show that digital economy has dual effect of promoting high-quality development and improving energy productivity in the Yellow River Basin.Energy productivity has a significant channel effect in the process of digital economy promoting high-quality development in the Yellow River Basin.The influence of digital economy development on the high-quality development of the Yellow River Basin is characterized by nonlinear increase of"marginal effect"and heterogeneity in terms of regional location and population size.
