摘　　要：基于2007—2020年中国31个省(市、自治区)面板数据,采用空间计量模型研究农业经济增长对农业碳排放强度的影响和空间溢出效应。结果表明,农业碳排放强度和人均农业生产总值表征的经济增长指标呈现以H-H集聚和L-L集聚为主的空间聚集模式;农用机械投入与农业碳排放强度指标呈正相关,农业种植业比重高的地区,农业碳排放强度就越高;经济增长和技术进步有利于减少当地农业碳排放强度。因此,应当统筹区域发展,促进区域协调发展,加大农业科技投入,提高农业环境污染防治方面的技术水平,利用空间相互作用,建立推动农业绿色生产的激励机制。Based on the panel data of 31 provinces(cities,autonomous regions)in China from 2007 to 2020,the impact of agricultur⁃al economic growth was studied on agricultural carbon emission intensity and the spatial spillover effect using a spatial econometric model.The results showed that the economic growth indicators represented by agricultural carbon emission intensity and per capita ag⁃ricultural GDP showed a spatial aggregation pattern dominated by H-H agglomeration and L-L agglomeration;the agricultural machin⁃ery input was positively correlated with the agricultural carbon emission intensity index.The higher the proportion of agricultural plant⁃ing,the higher the agricultural carbon emission intensity;economic growth and technological progress were conducive to reducing the intensity of agricultural carbon emissions in the region.Therefore,it was necessary to coordinate regional development,promote re⁃gional coordinated development,increase investment in agricultural science and technology,improve the technical level of agricultur⁃al environmental pollution prevention,use space interaction,and establish incentive mechanisms to promote agricultural green pro⁃duction.
