Abstract:With the fast economic growth, the development of industrialization and urbanization exerts great impact on the CO2 emissions. In this work, Time Series Data Model and Panel Data Model are established to explore the impact of industrialization and urbanization exerted on CO2emissions in different stages in China. The conclusion is that industrialization brought more CO2 emissions than urbanization did from 1993 to 2001, whereas, urbanization brought more CO2 emissions from 2002 to 2014. The factors of industrialization, per capita GDP and area of built district have positive impact on the CO2 emissions in the regions ofdifferent income level. The impact of urbanization varies in different regions.
