| 摘 要： | 农业技术的革新是增加农业产出的重要手段。本文以2012年我国全雌化牙鲆苗种推广调研数据为例，利用切换回归模型实证研究农业技术推广对农业产出的影响。研究发现，农业技术推广对农业产出有正效应，采用新技术的农业产出期望值大于采用传统技术的期望值。由此本文建议，应始终将科技创新作为重要的产业发展战略，并将提高农民素质作为增加农民收入的关键。

| Abstract: | Increasing extended agricultural technologies is an important way to increase agricultural yield. The study utilizes the research data of All-female Paralichthys olivaceus collected in 2012, and the impact of extended agricultural technologies on agricultural yield is estimated by utilizing the switching regression model. Our analysis reveals that extended agricultural technologies has a positive effect on agricultural yield, the expected agricultural yield under the extended agricultural technologies is larger than that of the traditional technologies. Thus this study suggests that we should always take technological innovation as an important industry development strategy, and improve the quality of smallholder＇s as the key to increase their income. |
