摘要
高标准农田建设关乎国家粮食安全保障.从改善灌溉设施、促进非农就业、增加农地租入和提高农业机械化的传导机制,构建了高标准农田建设对农户种植结构调整影响的理论分析框架,进而根据 2020 年和 2022 年中国乡村振兴综合调查(CRRS)10 省 50 县(市、区)300 村4378 个农户样本数据,采用面板数据双向固定效应模型,定量分析高标准农田建设的种植结构调整效应与政策异质性.结果表明:(1)高标准农田建设促使三大主粮作物种植比例提高了7.97%.(2)机制分析结果显示,高标准农田建设通过改善农地灌溉条件、增加农地租入规模和提高农业机械化来促进种植结构调整,而非农就业的传导机制未得到验证.(3)异质性分析表明,粮食平衡区、地形坡度和起伏度较大区域的高标准农田建设更能显著提高粮食种植比例.
Abstract
The construction of well-facilitated farmland is closely related to national food security.This paper constructs a theoretical analysis framework demonstrating the impact of well-facilitated farmland construction on crop planting structure through channels of improving irrigation facilities,increasing farmland rental,promoting non-agricultural employment,and boosting agricultural mechanization,and uses the sample data of 4378 farmers from 10 provinces,50 counties and 300 villages of the China Rural Revitalization Comprehensive Survey(CRRS)in 2020 and 2022 to quantitatively analyze the adjustment effect and policy heterogeneity of crop planting structure of well-facilitated farmland construction.The research results show that:(1)The construction of well-facilitated farmland has led to a 7.97%increase in the planting proportion of staple crops.(2)Mechanism test indicates that the construction of well-facilitated farmland increases the planting proportion of staple crops by improving agricultural irrigation facilities,increasing the scale of farmland rental,and increasing agricultural mechanization,while the transmission mechanism of non-agricultural employment has not been verified.(3)Heterogeneity analysis reveals that the construction of well-facilitated farmland in areas with a balance between production and consumption of grain,large topographic slopes,and undulations can much more significantly increase the proportion of grain planting by farm households.
