数字新质生产力对碳排放效率的影响
Impact of Digital New-quality Productivity on Carbon Emission Efficiency
摘要
Abstract
Based on the analysis of the influence mechanism of digital new-quality productivity on the carbon emission effi-ciency,this paper selects the panel data of 29 provinces in China from 2012 to 2021,and uses panel Tobit model,nonlinear re-gression model and system GMM model to empirically analyze the influence of digital new-quality productivity on carbon emission efficiency.The findings go as the following:There is a nonlinear effect of the digital new quality productivity on the carbon emis-sion efficiency,that is,with the development of digital new-quality productivity,the carbon emission efficiency shows a U-shaped characteristic of first decreasing and then increasing.There is a significant path-dependent effect on carbon emission efficiency,that is,there is a significant positive correlation between the current carbon emission efficiency and the previous carbon emission efficiency.The impact of digital new-quality productivity on carbon emission efficiency is stronger in the southern region.关键词
