摘要: 既有文献罕见同时关注粮食价格支持政策的农业经济增长效应和农业环境效应。区别于以往单一维度的研究,本文把粮食价格支持政策、农业经济增长和农业环境污染同时纳入一个分析框架中,利用异时DID模型和中介效应模型,对粮食价格支持政策与农业绿色增长之间的因果关系及作用机制展开实证检验。研究发现:粮食价格支持政策抑制了农业绿色增长,且该结论具有较强的稳健性;粮食价格支持政策能够通过作物种植结构调整和农业劳动力转移两条路径削减单位面积农业化肥面源污染和减少单位面积农业产值,最终合力引致该政策负向影响农业绿色增长。进一步分析发现,在目前的农业生产模式下,粮食价格支持政策难以兼顾农业"增长"与"绿色"。此结论对进一步把握粮食价格支持政策的影响效应及推动农业绿色增长具有重要的政策参考价值。

Abstract: The existing literature rarely focuses on the agricultural economic growth effect and agricultural environmental effect of food price support policies. Different from the previous single-dimensional research, this paper incorporates food price support policies, agricultural economic growth and agricultural environmental pollution into an analytical framework,using the heterogeneous timing DID model and the mediating effect model to tested empirically the causal relationship and mechanism between grain price support policies and agricultural green growth.The study found that:The grain price support policy inhibits the green growth of agriculture, and this conclusion has strong robustness. The grain price support policy can reduce the non-point source pollution of agricultural fertilizer per unit area and slow down the agricultural output value per unit area through the two-day path of crop planting structure adjustment and agricultural labor transfer, which finally leads to the negative impact of the policy on agricultural green growth.Further analysis shows that under the current agricultural production mode, grain price support policy is difficult to achieve the combination of agricultural 'growth' and 'green'.The conclusions of this paper will further grasp the impact of grain price support policies and promote the green increase of agriculture.

Key words: grain price support policy, agricultural green growth, heterogeneous timing DID, mediating effect
