The impact of green technology innovation on carbon emissions from the perspective of urban agglomeration:The moderating effect of human capitals
Under the goal of"carbon peaking and carbon neutrality",green technological inno-vation plays an important role in balancing high-quality economic development and carbon re-duction.This article is based on panel data from 209 cities in 19 urban agglomerations from 2006 to 2021.On the basis of depicting the spatiotemporal evolution pattern of green technolo-gy innovation and carbon emissions,this paper empirically explores the nonlinear impact of green technology innovation on carbon emissions and discusses the moderating effect of human capital on the impact.First,from 2006 to 2021,the level of green technology innovation in Chi-na's urban agglomerations showed an upward trend,and the growth rate of carbon emissions showed the characteristics of first growth and then decline,and the growth rate of carbon emis-sions in urban agglomerations with higher levels of green technology innovation is significantly lower than that with lower levels of green technology innovation.Second,green technology in-novation affects carbon emissions in an inverted"U"-shaped curve relationship that first pro-motes and then suppresses and it is affected by the level of urban agglomeration,geographical location,low-carbon policies,urban industrial structure and city scale.Third,human capital has a significant moderating effect on the impact of green technology innovation on carbon emis-sions.On the one hand,the increase in human capital strengthens the positive effect before the inflection point of the inverted"U"-shaped curve and the negative effect after the inflection point.On the other hand,it makes the carbon reduction threshold of green technology innova-tion level shifts to the right.The research conclusions of this article provide theoretical support and empirical evidence for improving human capital under the goal of"carbon peaking and car-bon neutrality".With the improvement of human capital as the starting point,we will give full play to the carbon reduction effect of green technology innovation and implement the concept of green and low-carbon development.
