采纳稻田综合种养模式能否提升农户效益?——以稻虾共作模式为例

Can the adoption of rice-aquaculture integrated cultivation mode improve farmers’benefits?A case study of rice and crayfish coculture pattern

为探究采纳稻田综合种养模式对农户效益的影响,基于2020年湖北省江汉平原地区调查数据,运用处理效应模型检验了采纳稻田综合种养模式对农户综合效益、经济效益、生态效益与社会效益的影响。结果表明:采纳稻田综合种养模式的农户具有较好的综合效益、经济效益和社会效益,但存在进一步拉大农户间效益差距的可能,且对农户生态效益的影响不显著;在异质性分析上,采纳稻田综合种养模式对不同规模和不同年龄农户的综合效益影响存在差异。由此提出如下建议,加强技术培训,完善绿色产品市场机制,引导农户绿色生产,有效识别不同群体农户的需求差异,在实现综合效益提升的同时,缩小农户内部效益差距。

In order to explore the impact of the adoption of rice-aquaculture integrated cultivation modeon farmers’benefits,based on the survey data of Jianghan Plain in Hubei Province in 2020,aprocessing effect model was used to test the impact of the adoption of rice-aquaculture integrated cultivation mode on farmers’comprehensive benefits,economic benefits,ecological benefits and social benefits.The results showed that:Farmers who adopted the riceaquaculture integrated cultivation mode had better comprehensive benefits,economic benefits and social benefits,but there was a possibility of further widening the benefit gap among farmers,and the impact on farmers’ecological benefits was not significant.In terms of heterogeneity analysis,there were differences in the comprehensive benefits of farmers of different sizes and ages.Therefore,the following suggestions are put forward to strengthen technical training,night green product market mechanism,guide farmers to green production,effectively identify the demand difference of different groups of farmers,and narrow the internal benefit gap of farmers while achieving comprehensive benefit improvement.
