摘要
Applying environmentally friendly technologies can reduce carbon emissions and promote sustainable agricultural development.Production risks are a key factor affecting farmers’organic fertilizer application(FOFA).This paper evaluates the impact and mechanisms of multidimensional risk perceptions(MRP)on FOFA in rural China.The results show that the risk perceptions of unstable land use rights,natural disasters,and price fluctuations have an inhibitory effect on FOFA.This result holds after a series of robustness checks.High concerns about land policies can reduce the inhibitory effect of risk perceptions of unstable land use rights on FOFA.Conversely,high concerns about climate change and a high proportion of agricultural income in total income enhance the inhibitory effect of risk perceptions of natural disasters and price fluctuations on FOFA.Farmers who differ in farmland size,in the distance from their homes to agricultural retail markets,and in whether they use the internet as an information source exhibit different risk perceptions of organic fertilizer use.China should further reduce the risk perception of unstable land use rights.It should strengthen the dessemination of scientific knowledge on climate change,and enhance farmers’environmental awareness of organic-fertilizer use.It should improve the pricing-reform policies for high-quality agricultural products and increase farmers enthusiasm to apply organic fertilizers.
有机肥施用可以降低农业碳排放和提高农产品品质,也是实现农业可持续发展的重要措施。农业生产风险是影响农户有机肥施用的关键,特别是在发展中国家。本文基于中国四川省水稻主产区农户调研数据,从农业生产风险视角,科学评估农户多维风险感知对其有机肥施用行为的影响、作用机理及调节效应。结果表明,高的地权不稳定性风险感知、自然灾害风险感知和农产品价格波动风险感知对农户有机肥施用行为具有明显抑制作用,这一结论经过系列稳健性检验后仍然成立。调节效应表明,对土地政策关注度高会降低地权不稳定风险感知对农户有机肥施用的抑制作用;对气候变化的关注度和水稻收入占总收入比高会增强自然灾害风险感知和农产品价格波动风险感知对农户有机肥施用的抑制作用。异质性分析表明,不同土地经营规模、家离集市距离不同和互联网是否为信息来源的农户不同风险感知对其有机肥施用行为具有较大差异。中国应进一步规范土地流转,降低农户对地权不稳定的风险感知;加强对农户气候变化科普知识宣传,提高有机肥施用的环保认知;完善农产品优质优价的价格改革政策,增强农户有机肥施用的积极性。
