来自具有全国代表性的印度农村家庭样本的家庭层面的面板数据，描述了与绿色革命相关的高产种子品种(HYV)的采用和盈利能力，被用来测试一个结合了边做边学和学习溢出的模型的含义。估计表明：(I)对新种子管理的不完善知识是采用的一个重大障碍；(Ii)随着农民使用新技术的经验的增加，这一障碍减少了；(Iii)自己和邻居使用HYV的经验显著增加了HYV的盈利能力；以及(Iv)农民在做出收养决定时没有充分纳入村庄的学习回报。
Household-level panel data from a nationally representative sample of rural Indian households describing the adoption and profitability of high-yielding seed varieties (HYVs) associated with the Green Revolution are used to test the implications of a model incorporating learning by doing and learning spillovers. The estimates indicate that (i) imperfect knowledge about the management of the new seeds was a significant barrier to adoption; (ii) this barrier diminished as farmer experience with the new technologies increased; (iii) own experience and neighbors' experience with HYVs significantly increased HYV profitability; and (iv) farmers do not fully incorporate the village returns to learning in making adoption decisions.
