Based on the survey data of vegetable growers in Beijing, Tianjin and Hebei in 2018, this paper uses OLS, QR and 3SLS to analyze the impact of informatization on farmers' income in the difference of information elements and personal endowment. The results show that as a whole, the information infrastructure input has an Income-increasing effect, the information technology adoption has no Income-increasing effect, and the two have no interaction. But for different income classes, the information infrastructure input and information technology adoption have an Income-increasing effect but a substitution relationship in high income class, while the information infrastructure input and information technology adoption have no Income-increasing effect or Income-decreasing effect respectively but a complementary relationship in low income class. Further, compared with the farmers lacking in material capital or human capital, the information infrastructure input and information technology adoption have more obvious Income-increasing effect on the farmers rich in material capital or human capital.
