数字经济发展对黄河流域碳排放的影响研究

Study on the Influence of Digital Economy Development on Carbon Emission in the Yellow River Basin

基于2010-2020年中国黄河流域75个地级市数据,采用固定效应模型,实证分析数字经济发展对黄河流域碳排放的影响。研究发现:数字经济发展对黄河流域碳排放的影响呈先促进后抑制的倒“U”型非线性关系;异质性分析发现数字经济发展对黄河流域中的大城市和省会城市碳排放影响呈显著的倒“U”型非线性关系;机制分析发现数字经济发展能够通过推动经济发展与促进城镇化,从而显著抑制黄河流域碳排放。

Selecting the data of 75 prefecture-level cities in the Yellow River Basin of China from 2010 to 2020,this paper empirically analyzed the impact of digital economy development on carbon emissions in the Yellow River Basin by using the fixed effect model.The results show that the impact of digital economy development on carbon emissions in the Yellow River Basin generally presents an inverted U-shaped nonlinear relationship of first promotion and then inhibition.Heterogeneity analysis shows that digital economy development has a significant inverted U-shaped nonlinear relationship on carbon emissions of big cities and provincial capitals in the Yellow River Basin.Mechanism analysis shows that the development of digital economy can significantly inhibit carbon emissions in the Yellow River Basin by promoting economic development and urbanization.
