区域差异视角下中国农业碳排放的时空特征与影响因素研究OACSTPCD

This study calculates the total agricultural carbon emissions based on the data of 31 provinces in China from 2011 to 2021.Using decoupling model,Moran index test and spatial Durbin model,this study explores the spatiotemporal characteristics and influencing factors of China's agricultural carbon emissions from the perspective of regional differences.The results show that:(1)There are significant regional differences in carbon emissions from agriculture in China,with carbon emissions showing a"high in the east and low in the west"characteristic.(2)There is a significant positive spatial spillover effect on agricultural carbon emissions,with the total agricultural output value having a"carbon reduction effect"on agricultural carbon emissions,and the level of agricultural mechanization and fiscal investment having a"carbon increase effect".(3)China's overall agricultural carbon emissions show a positive spatial clustering feature,and different regions have different decoupling characteristics.Based on this,policy recommendations are proposed from three aspects:implementing regional differentiation strategies,increasing agricultural technology investment,and promoting high-level policy measures,in order to promote the development of Chinese agriculture towards low-carbon and sustainable direction.
