Dynamics Evolution,Regional Differences and Spatial Agglomeration Characteristics of CO2 Emissions in Counties of China:Empirical Evidence from 2898 Districts and Counties in China from 2000 to 2019
Based on the panel data of CO2 emissions of 2898 counties(districts)in China from 2000 to 2019,the temporal and spatial evolution pattern of CO2 emissions at the county level in China was revealed by using the methods of nuclear den-sity estimation,Dagum Gini coefficient,standard deviation ellipse,and exploratory spatial data analysis.The results show that:(1)The CO2 emissions of the whole country and the four regions of the east,middle,west,and northeast are generally fluctuating and rising,among which the whole country and the east,middle,and northeast regions are multipolar,and the western region is polarized.(2)The overall difference in CO2 emissions in China shows a fluctuating upward trend,and the main source of the overall difference is composed of hyper-variable density and regional differences.(3)The spatial pat-tern of location distribution is northeast-southwest,and the distribution center tends to move northwest.(4)Spatial ag-glomeration patterns are mainly"high-high"agglomeration and"low-low"agglomeration,among which"high-high"ag-glomeration involves fewer counties and districts and is mainly distributed in Bohai Rim,Pearl River Delta,Northeast China,Pearl River Delta,Wuchang,Hong Kong,Macao and Taiwan,as well as the narrow strip at the junction of Ningxia,Shaanxi,Shanxi and Inner Mongolia.
