农业保险是改善环境的灵丹妙药吗？中国农户的化肥使用行为
Is Agricultural Insurance a Panacea for a Better Environment? Fertilizer Usage by Chinese Farmers
摘要
Agricultural insurance serves as a crucial tool for risk management, helping to lessen the impact of natural disasters on farming and ensuring rural economic stability. This study analyzes survey data from the 2020-2021 China Land Economic Survey. We employ a Propensity Score Matching-Difference-in-Differences (PSM-DID) method to assess the effect of agricultural insurance on farmers’ fertilizer use. Results indicate that insured farmers tend to spend more on chemical fertilizers. These findings remain consistent across various models and outcome measures. Additional analysis suggests that this effect primarily arises from changes in crop selection and farmers’ risk tolerance. Policymakers could consider designing insurance policies that link fertilizer application levels to subsidies, expanding education and agricultural training, and encouraging practices such as crop rotation.
中文摘要
农业保险作为风险管理的重要工具，有助于减轻自然灾害对农业生产的影响，保障农村经济稳定。本研究基于2020—2021年中国土地经济调查数据，采用倾向得分匹配—双重差分（PSM-DID）方法，评估农业保险对农户化肥使用的影响。结果表明，参保农户在化肥上的支出往往更高。这一发现在不同模型和结果衡量指标下均保持一致。进一步分析表明，该效应主要源于作物选择变化和农户风险承受能力。政策制定者可考虑设计将施肥水平与补贴挂钩的保险政策，扩大教育与农业培训，并鼓励轮作等做法。
