Abstract: Adaptation of green production technology is an important way to promote the green transformation of agricultural production.However, farmers are facing with many information difficulties in the process of technology adoption.With the development of digital rural development strategy, it is of great practical significance to explore the influence of farmers' digital information ability on their adoption of green production technology.Based on the survey data of 1 441 rice farmers in Jiangxi Province, this paper constructed a theoretical analysis framework of "digital information capacity-technology ecological cognition-technology adoption intensity".The Ordered Probit model and mediating effect model were used to explore the influence of digital information capacity on green production technology adoption and the mediating effect of technology ecological cognition.The results showed that digital information ability could significantly promote the adoption of green production technology by farmers.From all dimensions, digital information acquisition ability, judgment ability, sharing ability and application ability had a significant positive impact on the adoption of green production technology.The degree of impact was in the order of digital information acquisition ability>judgment ability>sharing ability>application ability.The results of mechanism analysis indicated that technological ecological cognition acted as an intermediary in the process of digital information ability affecting the adoption of green production technology.Specifically, digital information ability would positively affect green technology adoption behavior by improving farmers' technological ecological cognition.The results of heterogeneity analysis indicated that digital information ability had a significant positive impact on farmers' adoption of soil testing and fertilizer application technology, green pest prevention and control technology and organic fertilizer technology.However, it had no significant effects on the recovery of agricultural film pesticide packaging and straw crushing and returning to the field.In terms of operating scale, digital information ability had a greater effect on the adoption of green production technologies by large-scale households than by small farmers.Based on these, the paper proposed policy implications, including enhancing the cultivation of farmers' digital information ability and improving their ecological cognition level of green production technology.
