新疆农业碳排放的时空差异与空间溢出效应分析
Spatialtemporal differences and spatial spillover effects of agricultural carbon emissions in Xinjiang
摘要
Abstract
This paper evaluates the total amount and intensity of agricultural carbon emissions across 13 prefec-tures in Xinjiang,China from 2007 to 2020.It employs the Gini coefficient decomposition method to examine re-gional disparities in the intensity of agricultural carbon emissions in Xinjiang and utilizes the spatial Durbin mod-el to assess the spatial spillover effects and driving factors of these emissions.The findings indicate that the evolu-tion of total agricultural carbon emissions in Xinjiang during the study period can be categorized into three phas-es:a rapid increase,a continuous decline,and a steady rise,with straw burning being the predominant source of emissions,followed by livestock farming.The intensity of agricultural carbon emissions exhibited a pronounced downward trend throughout the period.Spatial disparities in the intensity of emissions at the beginning and end of the study period were substantial,characterized by lower levels in the north and higher levels in the south.Based on emission composition,Xinjiang can be classified into five distinct regional types.The Gini coefficients for the intensity of agricultural carbon emissions in Xinjiang as a whole,and specifically in its northern and south-ern parts,demonstrated a fluctuating downward trend,with inter-regional differences accounting for the majority of the overall disparities.Furthermore,there was a significant spatial agglomeration of emission intensity during the study period,with increasing spatial linkages among cities and towns over time.The primary influences on ag-ricultural carbon emissions in Xinjiang were market and governmental factors.At the market level,factors such as industrial agglomeration,agricultural industry structure,agricultural development level,and planting structure were significantly positively correlated with emission intensity,accompanied by notable inter-regional spillover effects.From a governmental perspective,the level of environmental governance and the extent of regional disas-ters exhibited a significant negative correlation with the intensity of agricultural carbon emissions.关键词
