摘要:

目的 适应性耕作行为是农户应对气候变化的关键策略。文章旨在探究气候变化信息因素和信息来源对农户适应性耕作行为存在的潜在影响。方法 通过构建“气候刺激—信息干预—适应行为”理论分析框架，阐明了政府部门、科研机构和邻里交流3类典型信息来源影响农户适应性耕作行为的内在机理。在此基础上，基于湖北省水稻主产区920户稻农的样本数据对理论猜想展开实证检验。结果 （1）来源于政府部门和科研机构的气候变化信息对农户适应性耕作行为有显著的正向影响，但在同时考虑3种信息来源的情景下，科研机构信息来源对农户的适应性耕作行为的正向影响最为强烈。（2）农户在获得政府部门、科研机构和邻里交流的气候变化信息后，他们在气候变化适应性耕作行为方面差异主要取决于其气候变化认知而非主体信任因素。结论 政府部门和科研机构等为代表的正式组织的气候变化信息对农户适应性耕作行为的积极影响更为显著，但这种影响很大程度上取决于农户所获得的信息能否提高其气候变化认知。

Abstract:

Adaptive tillage behavior is the key strategy for farmers to cope with climate change，and there is a potential influence of information factors and sources of information on farmers' behavioural decisions. By constructing a theoretical analysis framework of "climate stimulation-information intervention-adaptive behavior", this paper clarified the internal mechanism of three typical information sources, namely government departments, scientific research institutions, and neighborhood communication, affecting farmers' adaptive farming behavior. On this basis, the theoretical conjecture was tested empirically based on the sample data of 920 rice farmers in the main rice producing areas of Hubei province. The results showed that: (1) Climate change information from government departments and scientific research institutions had a significant positive impact on farmers' adaptive tillage behavior, but when the three information sources were considered simultaneously, the information source from scientific research institutions had the strongest positive impact on farmers' adaptive tillage behavior. (2) After receiving the climate change information from government departments, scientific research institutions, and neighborhood exchanges, the differences of farmers' climate change adaptation tillage behavior mainly depended on their climate change cognition rather than the subject trust factor. Based on the above findings, it is suggested that the climate change information from official organizations, such as government departments and scientific research institutions, has a more significant positive impact on farmers' adaptive tillage behavior. However, this impact largely depends on whether the information obtained by farmers can really improve their awareness of climate change.
