中文摘要：

在对鄱阳湖生态经济区内湖区、平原、丘陵3种地形的838户种稻大户调查数据进行统计分析的基础上，利用二元Logistic模型对影响农户技术应用时机选择的因素进行实证研究，发现不同地形上种稻大户农业技术应用时机选择的影响因素不同。在湖区，农户的受教育水平对农户应用农业技术的时机有显著正向影响；在平原地区，水稻种植收入比重、获取信息来源途径及数量对农户应用农业技术的时机有显著正影响；在丘陵地区，家庭总收入、劳动力工资评价、农业基础设施评价对农户应用农业技术都有显著正影响，而家庭外出务工人数有显著负影响。为此，提出要促进教育和增收，同时增强信息沟通；要优化外部环境，丘陵地区要格外注重农业生产基础设施建设。

英文摘要：

This paper studied the factors affecting large scale rice farmers in their timing to adopt new technology based on three landforms, namely, lakes, plains and hills by applying Logistic model. It found that different landforms have different influence. In lake areas, people＇ s level of education is positively related with the timing. In plain areas, the ratio of rice income and assessment of laborers＇ wage has a positive effect on the timing. And in hill areas, a family＇ s total income, and assessment of laborers＇ wages and agriculture infrastructure are positively related with it. The number of outdoor-workers in a family has a negative influence. Finalty, the paper proposed that it is important to promote education, increase income, and strengthen information communication. Meanwhile, it is necessary to optimize the external environment and improve agriculture infrastructure in hill areas.
