【摘要】 2000年12月1日《中华人民共和国和种子法》的颁布实施，我国种子产业从计划经济开始全面步入市场经济，种子经营发生了根本性变化，打破了过去国有种子部门通过行政手段垄断种子市场的格局，农民种植的主要农作物品种由国有种子部门逐级统供而被农户自愿购种所取代。农户选择新品种的决策因素也由过去较为单一的政府干预转为多影响因素。随着种子市场的放开，种子经营单位和新品种数量急剧增加，给农户选择新品种提供了充足的机会，农户在多因素的影响下，结合自身的实际作出决策，可以自主地选择农作物新品种。 本文是在种子市场新的形势和“农户可以自主选购种子及农户是理性经济人”的假设下，采用参与式研究方法，对贺州市农户选择新品种的决策因素进行调查研究，研究结论如下： 1、农户选择新品种的决策过程，实质上是核算新增总成本并与新增总收益比较的过程，农户作出选择农作物新品种的最终决策是各种影响因素综合作用的结果。《种子法》实施后，影响农户选择新品种决策的关键因素有新品种的价格、新品种的特性、广告宣传、农民的文化水平、经济状况、土地、劳动力等。 2、农户作出选择新品种的决策是理性的，农户是在有约束条件下追求效用最大化的理性经济人。 本文主要是对《种子法》实施后农户选择新品种的决策因素进行分析研究，并根据研究结论提出了相关建议，有助于种子生产、经营者和农户更加理性地决策，使农户普遍选择优良新品种，达到增产增效的目的。更多还原
