数字经济对黄河流域碳排放的影响机制研究
Study on the Influence Mechanism of Digital Economy on Carbon Emission in the Yellow River Basin
摘要
Abstract
In order to investigate the effect and mechanism of digital economic development on carbon emission in the Yellow River Basin,based on the panel data of 76 prefecture-level cities in the Yellow River Basin from 2011 to 2020,we measured the level of digital economic development,the total amount of carbon emission and the intensity of carbon emission in the Yellow River Basin,and built an individual and time two-way fixed-effects model to conduct empirical analysis,and conducted robustness tests on the results of the lagging effect of digital economic development,changing the sample capacity,and substitution variables.The empirical results are tested for robustness such as lagged effect of digital economic development,changing sample capacity,and substitution of variables,the mechanism of technological pro-gress and industrial structure upgrading,and the heterogeneity of location and heterogeneity of resource endowment of carbon emission reduc-tion effect of digital economic development.The results show that a)the digital economic development has a significant inhibitory effect on carbon emission intensity and total carbon emission in the Yellow River Basin.b)Technological progress and industrial structure upgrading are important mechanisms for digital economic development to promote carbon emission reduction in the Yellow River Basin.c)There is sig-nificant location heterogeneity and resources endowment heterogeneity in the inhibitory effect of digital economic development on carbon emis-sion in the Yellow River Basin,and the inhibitory effect on carbon emission in the middle and upstream areas of the Yellow River is signifi-cantly better than that in the downstream areas,and the inhibitory effect on carbon emission in the middle and downstream areas is signifi-cantly worse.The inhibition effect on the total carbon emissions in the middle and upper reaches of the Yellow River is significantly better than that in the lower reaches,the inhibition effect on the carbon emission intensity in the upper reaches has not yet appeared,and the inhi-bition effect on the carbon emissions of non-resources cities is significantly greater than that of resources cities.Countermeasures and sugges-tions are put forward to coordinate the coordinated development of the digital economy in the Yellow River Basin,strengthen the promotion of green and low-carbon technological innovation,accelerate the transformation and upgrading of the industrial structure,implement differentia-ted digital economy development strategies,and effectively curb carbon emissions.关键词
