[目的]高标准农田建设政策作为"两藏"战略的重要实践,是破解农村高用工成本与低机械化水平的重要途径之一,评估其对机械替代劳动的影响具有重要的现实意义和理论价值。[方法]本文以诱致性技术变迁理论为基础,基于准自然实验思路,利用2005-2021年中国省级面板数据和江西省3个县两期的农户数据,采用双重差分法(DID)评估高标准农田建设政策在劳动成本上升条件下对机械替代劳动的影响。[结果]①随着劳动力成本不断上升,农户倾向于采用机械替代劳动的策略。②在农村劳动力成本上升前提下,高标准农田建设政策增强了机械替代劳动的效应。③高标准农田建设政策在粮食主产区、劳动力输出主要地区和大规模农户中对机械替代劳动的促进效应更为显著。④高标准农田建设政策通过降低坡耕地比例、改善农村道路和减少地块细碎化等途径增强了机械替代劳动的效应。[结论]为增强高标准农田建设政策对机械替代劳动的效应,需要精准施策,全方位夯实粮食安全根基。建议加强坡耕地综合治理,改善农村道路,减少地块细碎化程度,推动农业机械化发展,从而强化"藏粮于地、藏粮于技"的物质基础。
Impact of High-standard Farmland Construction policy on labor substitution by machinery in China:Evidence from quasi-experimental approaches at the macro and micro levels
[Objective]High-standard Farmland Construction(HSFC)policy,as an important practice of implementing the"storing grain in the land and technology"strategy,is one of the important ways to break the dilemma of high labor costs in rural areas and low mechanization level.Assessing its impact on the substitution of labor by machinery has important practical significance and theoretical values.[Methods]Rooted in the induced technological changes theory,this study employed the difference-in-differences(DID)method to assess the impact of HSFC policy on labor substitution by machinery under the condition of rising labor costs using provincial panel data(2005-2021)and household survey data of two periods from three counties in Jiangxi Province.[Results](1)In the backdrop of selective labor transfer and rising prices,farmers increasingly favored labor substitution by machinery.(2)HSFC policy enhanced effects on labor substitution by machinery.(3)Pronounced effects of HSFC policy were observed in grain-producing areas,regions with significant labor outflows,and among large-scale farmers.(4)The HSFC policy,through measures like reducing sloping land and improving rural infrastructure,effectively enhanced labor substitution efficiency.[Conclusion]To enhance the effect of labor substitution by machinery from the HSFC policy,precise measures are required to comprehensively solidify the foundation of food security.Enhancing integrated management of sloping farmland,improving rural roads,and reducing land fragmentation are essential measures for achieving agricultural mechanization.This effort strengthens the material foundation for storing grain in the land and storing grain through technology.
