摘要
保障农民种粮收益是夯实国家粮食安全之基的关键,而提升农户粮食价格加成则是保护农民种粮积极性的重要途径之一。本文基于2001~2021年全国小麦主产省省级面板数据,构建农户粮食价格加成测度模型,探讨农业基础设施建设对农户粮食价格加成的影响及作用途径。研究发现:考察期内农户小麦价格加成水平整体呈现波动上升趋势,且产麦大省价格加成水平具有明显优势。基准回归结果显示,农田水利、农村交通、农业电力设施对农户粮食价格加成均具有显著正向影响,这一结论经过稳健性检验仍然成立。异质性分析表明,农业基础设施对农户粮食价格加成的影响受样本所在区域的调节,与产麦大省相比,其他省份的影响表现得更为明显。并且,上述影响在农户粮食价格加成水平不同分位点上也表现出显著差异,农田水利和农村交通设施的影响随着分位点提高而呈现加剧上升趋势,但农业电力设施的影响则相反,在较低分位点的影响反而更高。作用路径分析表明,农业基础设施建设通过改善农户粮食销售价格和降低农户粮食生产成本来促使农户粮食价格加成水平提升。因此,应因地制宜继续加大农业基础设施建设投入,充分发挥农业基础设施建设在调动农民种粮积极性中的作用。
Ensuring the benefits of grain farmers is the key to strengthen the foundation of national food security,and the enhancement of farmers’grain price markup is one of the important ways to mobilize farmers’enthusiasm for growing grain.Based on the provincial panel data of wheat-producing provinces from 2001 to 2021,this study constructs a model for measuring farmers’grain price markup to analyse the impact of agricultural infrastructure construction on farmers’grain price markup and its mechanism.Results are as follows:The overall wheat price markup level shows a fluctuating upward trend during the study period,and the price markup level in major wheat-producing provinces has a significant advantage;the results of the benchmark regression indicate that farmland imigation and water conservancy,rural transportation,and agricultural electricity facilities all have a significant positive impact on farm household grain price markup;this conclusion still holds after the robustness test.The heterogeneity analysis shows that the impact of agricultural infrastructure on farm household food price markup is moderated by the region where the sample is located,and the impact is more pronounced in other provinces than in large wheat-producing provinces;moreover,the above impact also shows significant differences at different quartiles of farm household food price markup levels,with the impact of farmland imnigation and water conservancy and rural transportation facilites showing an increasing trend as the quartiles increase,but the impact of agricultural electricity facilities,on the contrary,is higher at the lower quantile points.The mechanism analysis suggests that agricultural infrastructure construction contributes to the increase in the level of farm food price plus by improving grain price and reducing grain production costs.Therefore,we should continue to increase the investment in agricultural infrastructure construction according to local conditions and give full play to the role of agricultural infrastructure construction in mobilizing farmers’enthusiasm for growing food.
