【摘要】 为明确稻虾共作模式农户减量化投入行为的关键影响因素，基于江苏、湖北及湖南3省671份农户调查数据，采用Logistic模型与解释结构模型(ISM),分析了稻虾共作模式农户减量化投入行为的影响因素及其层级结构。结果表明：稻虾种养技术了解程度和政府种养管控是深层根源因素，稻虾种养面积和稻虾种养环境污染认知为中间因素，农资投入依据和稻虾种养补贴是直接驱动因素。为进一步引导农户农资投入减量化、保护稻虾种养模式农业生态环境，需要优化稻虾共作的补贴执行机制，完善政府环境管控的奖惩机制，强化农户对稻虾种养技术的认知，提高农户环境保护意识。更多还原

【Abstract】 In order to clarify the key influencing factors of farmers’ reduced investment behavior in rice-shrimp co-cropping mode, based on the survey data of 671 farmers in Jiangsu, Hubei and Hunan provinces, Logistic model and ISM model were used to analyze the influencing factors and hierarchical structure of farmers’ reduced investment behavior in rice-shrimp co-cropping mode. The results show that the understanding of rice-shrimp breeding technology and the government’s breeding control are the deep root factors, the rice-shrimp breeding area and the cognition of rice-shrimp breeding environmental pollution are the intermediate factors, and the agricultural investment basis and rice-shrimp breeding subsidies are the direct driving factors. In order to further guide farmers to reduce agricultural investment and protect the agricultural ecological environment of rice shrimp farming mode, it is necessary to optimize the subsidy implementation mechanism of rice shrimp farming, improve the reward and punishment mechanism of government environmental control, strengthen farmers’ cognition of rice shrimp farming technology, and improve farmers’ awareness of environmental protection.更多还原
