摘要
在新时代国家粮食安全战略与农业高质量发展双重背景下,深入探究农业直接补贴政策对粮食全要素生产率(TFP)的深层次作用机制,以期为精准优化补贴政策框架、强化补贴效能,驱动粮食生产向高质量发展转型提供理论支撑与实证依据。基于2006—2022年23个粮食生产省份面板数据,运用双向固定效应模型、中介效应分析框架、面板分位数回归技术,系统评估了农业直接补贴政策的直接影响、内在作用机制及不同条件下的边际效应。研究发现:农业直接补贴的实施有效促进了粮食TFP提升,成为推动粮食生产高质量发展的关键力量,同时该效应具一定时滞性;从边际效应来看,农业直接补贴政策对提升中低效率地区的粮食TFP的效果更显著;从影响机制来看,农业直接补贴主要通过抑制无序扩张,促进粮食适度规模经营来提高粮食TFP。但受限于补贴力度,其对农业技术推广的激励作用尚需增强;区域异质性分析结果表明,西部地区及粮食主产区享受补贴政策红利方面展现出更强的响应性。鉴于此,建议加大农业直接补贴的投入力度,优化补贴分配机制,优先向生产效率较低及经济欠发达的粮食主产区域倾斜,以更好地发挥补贴政策对粮食生产高质量发展的促进作用,同时确保农业支持保护政策体系的持续稳定与高效运行。
In the dual context of the national grain security strategy for the new era and the pursuit of high-quality agricultural development,this study delves into the profound mechanisms by which agricultural direct subsidy policies influence the total factor productivity of grain(TFP).The goal is to provide theoretical underpinnings and empirical evidence for the precise optimization of subsidy policy frameworks and to enhance the efficacy of subsidies,thereby facilitating the transition of grain production towards high-quality development.Utilizing panel data from 23 grain-producing provinces spanning the years 2006 to 2022,this research employs a two-way fixed effects model,a mediation effect analysis framework,and panel quantile regression techniques to systematically assess the direct impact,intrinsic mechanisms,and marginal effects under various conditions of agricultural direct subsidy policies.The study reveals that the implementation of agricultural direct subsidies significantly boosts grain TFP,emerging as a pivotal force in advancing the high-quality development of grain production,albeit with a certain degree of time lag in its effects.Regarding marginal effects,the policy is found to be particularly effective in enhancing TFP in regions with medium to low efficiency levels.In terms of impact mechanisms,agricultural direct subsidies primarily elevate grain TFP by curbing indiscriminate expansion and fostering moderate-scale grain operations.However,given the limitations in the intensity of subsidies,there is a need to strengthen their incentive effects on the dissemination of agricultural technology.Regional heterogeneity analysis indicates that the western regions and major grain-producing areas exhibit a more pronounced responsiveness to the benefits of subsidy policies.Consequently,it is recommended to augment investment in agricultural direct subsidies,prioritize the subsidy allocation mechanism,and focus on areas with lower production efficiency and underdeveloped economies to better leverage the role
