Climate change and carbon dioxide emissions problems have attracted worldwide attention.Generally speaking,the carbon dioxide emissions of a country are decided by the interaction of many factors,and the role of these factors may be different.Using data of China’s 30 provinces,this paper analyzes the relationship between carbon dioxide emissions and population,economy and technology based on dynamic panel model.The results show that the influence of population,economy and technology on carbon dioxide emissions varies across different regions.While the relationship between population and carbon dioxide emissions is mutual,economic growth increases carbon emissions,but the technological progress reduces it.In addition,China’s carbon dioxide emissions are clearly path dependence;that is,current economic growth will affect the air quality after one to three years.Based on these findings,this paper provides suggestions to reduce carbon dioxide emissions in order to facilitate China’s low-carbon economy.
