| 为了精确探究农机购置补贴、农业技术补贴及有机肥价格补贴对农户有机肥施用行为的激励影响，本研究基于2023年1月1日至30日陕西省关中地区12个县的农户随机抽样调查数据，运用结构方程模型（SEM）估算了影响农户有机肥施用行为的相关因素载荷系数。结果表明：农业补贴潜变量（ASF）的标准化路径载荷值为0.690，对农户有机肥施用行为产生了显著正面影响；在各种农业补贴中，农机购置补贴（MAS）的标准化路径载荷最高，为0.690，农业技术补贴在提高农户对有机肥与农产品市场认知上起到了正面作用；农业技术培训（TES）的影响显著，标准化路径载荷值为 0.634；有机肥价格补贴（FES）的标准化路径载荷为0.597，是所有补贴中的最低值；农户主要劳动力年龄（AGE）及教育水平（EDU）的标准化路径载荷均达到了显著影响水平。农业补贴对不同经济条件下及不同作物种植户的影响显示出显著差异。研究指出，劳动强度是影响农户施用有机肥的主要障碍，积极的态度是推动农户施用有机肥的根本驱动力，3种农业补贴对提高粮农有机肥利用率的作用有限，需对相关政策标准和实施方法进行针对性的调整。 |

| In this study, we aimed at assessing the incentive of agricultural machinery purchase subsidies, agricultural technology subsidies, and organic fertilizer price subsidies on how farmers apply organic fertilizers. Therefore, we applied a structural equation model to estimate the load coefficients of the related variables on the fertilization strategies farmers use and built a dataset based on a random survey of farmers in 12 counties in the Guanzhong Plain of China between January 1-30, 2023. Our results revealed a standardized path coefficient of the agricultural subsidy latent variable（AFS）of 0.690, demonstrating a significantly positive effect on organic fertilizer application by the farmers. Among the three agricultural subsidies, the agricultural machinery purchase subsidy variable（MAS）displayed the highest standardized path coefficient of 0.690. Agricultural technology subsidies positively influenced the organic fertilizer - and agricultural-product-related market awareness of the farmers. Moreover, the agricultural technology training variable（TES）positively and significantly impacted how farmers applied organic fertilizers, with a standardized path coefficient of 0.634. The organic fertilizer price subsidy variable（FES）exhibited the lowest standardized path coefficient（i.e., 0.597）among all the assessed agricultural subsidies. The standardized path coefficients for the age（AGE）and education（EDU）characteristics of the farmers were also significant. The impact of agricultural subsidies on farmers with different economic conditions and crop types was significantly different. In conclusion, we emphasize that labor intensity is the main barrier for farmers to apply organic fertilizers, while the positive attitude of farmers towards organic fertilizers serves as the motivational basis to promote organic fertilizer application. The three agricultural subsidy types affect moderately the fertilizer strategies of grain farmers. The relevant standards and implementation methods of the aforementioned agricultural subsidies require adjustments. |
