The urbanization and carbon emissions in China have greatly positive correlation. In the short term, the long-run equilibrium relationship of carbon emissions and urbanization level greatly influences deviation from the current equilibrium level of carbon emissions; in the long-term, the increase in carbon emissions is associated with short-term urbanization level upsurge. The interaction between urbanization and carbon emissions in China has a phenomenon of “time delay.” And urbanization is carbon emissions Granger causality, but carbon emissions are not urbanization Granger causality. Therefore， the push on the urbanization in China should concern about carbon emissions, focus on environmental protection, and build the Low-carbon City.
