摘　　要：利用江苏水稻种植户调查数据,探讨生物农药技术的跨期属性以及由此引致的农户采用行为。研究发现,生物农药技术具有跨期收益特点,在保证作物产量不受影响的情况下,生物农药累计使用年限越长,农药减量效果越明显。由于生物农药的跨期属性,不同规模农户的采用行为表现出明显差异。相比于小农户,规模户时间偏好较弱,更注重长期收益,较倾向于采用生物农药技术。进一步发现,对于规模户,较长的地权期限影响技术收益,对其采用生物农药行为有促进作用。对此,应大力宣传生物农药技术的跨期特点,对不同规模农户的技术采用行为采取差异化的激励方式,促进生物农药技术采用。Using survey data from rice growers in Jiangsu, this study explores the cross-period attributes of biopesticides technology and the resulting adoption behavior of farmers. Research has found that biopesticides technology has the characteristic of cross period benefits. While ensuring that crop yield is not affected, the longer the cumulative service life of biopesticides is, the more significant the pesticide reduction effect is. Due to the cross-period nature of biopesticides, there are significant differences in the adoption behavior of farmers with different scales. Compared to small-scale farmers, large-scale farmers have weaker time preferences and focus more on long-term benefits, preferring to use biopesticides technology. Furthermore, it was found that for large-scale farmers, longer land tenure affects technological benefits and promotes their adoption of biopesticides. In this regard, it is necessary to vigorously popularize the cross-period characteristics of biopesticides technology, and use differentiated incentive methods for farmers with different scales to adopt biopesticides technology.
