Causal Relationships among Population and Carbon Dioxide Emissions

The carbon dioxide emissions of the provinces would be calculated from 1995 to 2008.And we compare the provinces’ carbon dioxide emissions and population development.We found that the relationship between population and carbon dioxide emissions are not a simple correlation.In order to probe the relation,we introduce the economic variable into the research,take advantage the cointegration analysis and Granger causality test.The paper found that the population and economic growth is the main reason of carbon dioxide emission change.In short run the population growth would impact the carbon dioxide emissions,and increase in carbon dioxide emissions cannot be simply attributed to overpopulation,economic growth impact on carbon dioxide emissions more strongly.
