摘　　要：厘清农业“水—能源—粮食”系统协同的生态效应对于促进农业绿色低碳发展具有重要意义。为此,基于中国2000—2021年的省际面板数据,采用双向固定效应模型考察农业“水—能源—粮食”系统协同对农业生态环境的影响,而后构建中介效应模型和调节效应模型进一步明晰二者间的作用机制。研究结果显示:(1)农业“水—能源—粮食”系统协同能够显著提高农业生态环境质量,且经过一系列稳健性检验后结论依然成立。(2)异质性分析表明,农业“水—能源—粮食”系统协同的生态效应在粮食主产区和中西部地区更加显著。(3)作用机制检验发现,农业“水—能源—粮食”系统协同主要通过规模化经营和种植结构调整提高农业生态环境质量,环境规制在农业“水—能源—粮食”系统协同的生态效应中产生正向调节作用。基于此,需建立以水资源节约集约利用为核心的粮食高质量发展机制;重视规模化经营及种植结构调整在提高农业生态环境质量中发挥的重要作用;积极探索差异化的区域农业“水—能源—粮食”协同政策;不断完善农业环保政策。Clarifying the ecological effects of the agricultural“water-energy-food”system synergy is of great significance for promoting green and low-carbon agricultural development.Therefore,based on the inter-provincial panel data from 2000 to 2021 in China,a bidirectional fixed effects model was used to investigate the impact of agricultural“water-energy-food”system synergy on the agricultural ecological environment.Then,a mediation effect model and a regulatory effect model were constructed to further clarify the mechanism action between the two.The research results show that:(1)The synergy of the agricultural“water-energy-food”system can significantly improve the quality of agricultural ecological environment,and the conclusion is still valid after a series of robustness tests.(2)Heterogeneity analysis shows that the ecological effect of the agricultural“water-energy-food”system synergy is more significant in the main grain producing areas and the central and western regions.(3)The mechanism test found that the synergy of the agricultural“water-energy-food”system mainly improves the quality of agricultural ecological environment through large-scale management and planting structure adjustment,and environmental regulations have a positive regulatory effect on the ecological effect of the agricultural“water-energy-food”system synergy.Based on this,it is necessary to establish a high-quality grain development mechanism with water resource conservation and intensive utilization as the core.Emphasize the important role of large-scale management and planting structure adjustment in improving the quality of agricultural ecological environment.Actively explore differentiated regional agricultural“water-energy-food”collaborative policies.Continuously improve agricultural environmental protection policies.
