农业科技创新在提高农产品产量和质量的同时也面临促进农户增收的困境,而生态效率的提高也可能造成农户收入不平等的问题。为进一步探究农业科技创新水平、生态效率与农户增收三者之间的关系,根据2000—2020年间湖南省的时间序列信息,利用面板向量自回归模型,采用协整检测、格兰杰检测、方差分解等各种手段,对农业科技创新水平、生态效率和农户增收质量间的相关性开展实证分析,以为处理好农业发展、农户收入和生态环境保护之间的关系提供理论参考。结果显示:农业科技创新与农户增收质量之间存在显著的双向正向关系,即科技创新在提升农业生产效率和质量的同时显著促进了农户的经济增长,但生态效率的提升在短期内未能显著转化为农户的经济收益;农业科技创新对农户增收质量的影响即时且显著,并随着时间推移而趋于稳定;在预测农户增收质量时,农业科技创新的作用明显超过生态效率。基于此,从长期规划生态效率提升、加大农业科技创新的支持与投资和增强农户生态环保意识等方面提出政策建议。
