Spatial analysis on China's regional air pollutants and CO2 emissions: emission pattern and regional disparity
Abstract China has suffered from serious air pollution and CO2 emission. Challenges of emission reduction policy not only come from technology advancement, but also generate from the fact that, China has pronounced disparity between regions, in geographical and socioeconomic. How to deal with regional disparity is important to achieve the reduction target effectively and efficiently. This research conducts a spatial analysis on the emission patterns of three air pollutants named SO2, NOx and PM2.5, and CO2, in China's 30 provinces, applied with spatial auto-correlation and multi regression modeling. We further analyze the regional disparity and inequity issues with the approach of Lorenz curve and Gini coefficient. Results highlight that: there is evident cluster effect for the regional air pollutants and CO2 emissions. While emission amount increases from western regions to eastern regions, the emission per GDP is in inverse trend. The Lorenz curve shows an even larger unequal distribution of GDP/emissions than GDP/capita in 30 regions. Certain middle and western regions suffers from a higher emission with lower GDP, which reveal the critical issue of emission leakage. Future policy making to address such regional disparity is critical so as to promote the emission control policy under the “equity and efficiency” principle.
Highlights Conduct a spatial analysis on China's provincial air pollutants and CO2 emissions. Spatial auto-correlation and multi-linear regression is made to identify emission pattern in 30 regions. Analyze the regional disparity and inequity with Lorenz curve and Gini coefficient. Regional inequity and emission leakage is highlighted. Regional oriented pollution control policy is proposed and discussed.
