数字经济对中国省际大气环境效率的影响研究
Research on the Impact of Digital Economy on Atmospheric Environmental Efficiency
摘要
Abstract
This study utilizes panel data from 30 provinces and cities in China from 2012 to 2020 to analyze the atmospheric environ-mental efficiency across different regions.The Super Efficiency DEA(Data Envelopment Analysis)model is applied to calculate the environmental efficiency for each province and city,while a panel Tobit model is constructed to explore the impact of the development of the digital economy on atmospheric environmental efficiency.The results show that the overall atmospheric environmental efficiency in China remained relatively low throughout the period,consistently ranging between 0.6 and 0.7,with little variation.Significant re-gional disparities were observed,with the eastern region exhibiting the highest atmospheric environmental efficiency,while the central and western regions had values below the national average.Furthermore,the study reveals a significant positive correlation between the development of the digital economy and atmospheric environmental efficiency.Further analysis indicates that the digital economy posi-tively affects the atmospheric environmental efficiency in the eastern and western regions,but its influence in the central region is not statistically significant.Based on these findings,the article proposes several policy recommendations aimed at improving atmospheric environmental efficiency.关键词
