基于浙江、江西、安徽、湖南四省342户农户水稻种植的微观数据，运用统计分析方法，研究影响长江中下游稻区农户用种行为的主要因素。结果显示，农户用种行为受水稻种植规模、农户年龄、从事水稻种植年份、信息获取难易程度和是否拥有农业保险等因素影响。提出相应对策建议：通过育种政策引导培育广适性品种，提升农业技术推广的深度和广度，通过补贴政策引导鼓励农户适度规模经营，培育家庭农场等新型农业经营主体，扩大农业保险以提升稻农抗风险能力。

The paper used statistical analysis methods to study the factors that affect the behavior of farmer using rice seeds in the area of the middle and lower reaches of the Yangtze River based on the micro data of 342 farmers’ rice planting in Zhejiang, Jiangxi, Anhui, and Hunan provinces. The results showed that the behavior of farmers in using rice seeds is affected by factors such as the scale of rice planting, the age of the farmers, the year the farmers have been engaged in rice planting, the difficulty of obtaining agriculture information, and whether the farmers have agricultural insurance or not. The author puts forward corresponding countermeasures and suggestions: guiding the cultivation of widely-adapted rice varieties, and increasing the depth and breadth of agricultural technology extension through breeding policies, encouraging farmers to operate on an appropriate scale, cultivating new agricultural business entities such as family farms, and expand agricultural insurance to enhance the risk-resistant ability of rice farmers through the guidance of subsidy policies.
