摘　　要：碳足迹可以衡量人类活动对生态系统的影响,探究农业产业集聚对农田生态系统碳足迹的影响效应对于促进农业高质量发展具有重要的现实意义。本文运用2000—2019年省际面板数据,通过构建空间杜宾模型实证分析农业产业集聚对农田生态系统碳足迹的影响,结果表明:2000—2019年全国农田生态系统碳足迹总体上呈下降趋势,且具有明显“南高北低、东高西低”的特征;农田生态系统碳足迹具有显著的空间正相关性;农业产业集聚对农田生态系统碳足迹的影响存在空间溢出效应且具有区域异质性。基于以上结论,本文从推动农业产业合理集聚、加强区域之间农业碳减排合作以及因地制宜施策等方面提出相关对策建议。Carbon footprint can reflect the impact of human activities on ecosystems,and exploring the impact of agricultural-industrial agglomeration on the carbon footprint of farmland ecosystems is of great practical significance for promoting high-quality agricultural development.This paper uses the inter-provincial panel data from 2000 to 2019 to empirically analyze the impact of agro-industrial agglomeration on the carbon footprint of farmland ecosystem by building a spatial Durbin model.The results show that:first,the carbon footprint of farmland ecosystem in China from 2000 to 2019 shows a downward trend in general,and has the obvious characteristics of"high in the south and low in the north,high in the east and low in the west".Second,the carbon footprint of farmland ecosystems has a significant spatial positive correlation.Third,there is a spatial spillover effect and regional heterogeneity in the impact of agro-industrial agglomeration on the carbon footprint of farmland ecosystems.Based on the above conclusions,this article proposes relevant countermeasures and suggestions such as promoting the rational agglomeration of agriculture and industries,strengthening regional cooperation in agricultural carbon reduction,and implementing policies tailored to local conditions.
