Second, the higher the risk aversion of farmers, the more unfavorable the improvement of their willingness to adopt technology, and the negative impact on actual adoption behavior. Third, there is a scale threshold for farmers' technology adoption willingness and behavior, with a threshold value of 15 mu. The number of Left-behind labor force has no significant difference on technology adoption behavior under different scales. The improvement of risk aversion degree has a significant negative impact on the willingness and behavior of different scales of households.
